Trend Following: Part 2

TLDR: I could not find a worthwhile systematic trend following fund to buy into, as I don't live in the US.

I don't have enough capital to do-it-myself and diversify among many markets, so I looked to buy into a fund.

    Past Performance

    What type of returns can you get?

    Use the SG Trend Index (previously the NewEdge Trend Index) to benchmark trend-following funds' performance.  It's a simple index, rebalanced and reconstituted at the start of each year, currently consisting of the ten largest managers (by AUM) that meet their criteria.  Before 2012, it had a wider range of constituents, with similar selection criteria.  

    I selected funds from Jezebel Liberty's Trend Following Wizards page (the ones I could get data for), and charted their performance against the SG Trend Index and S&P500.



    (Data source: IASG)

    The percentage increase and CAGR for those funds active the entire period:


    A few funds have astounding returns: 10 times your money!  Most give between 2 and 6 times.  The SG Trend index gives 2.7 times.  But before running off to buy, these funds were winners selected with hindsight, and are not now available to retail investors.  You can't buy the SG Trends Index either.

    So a lot depends on which fund you choose.  I couldn't find why the different funds performed so differently.  Perhaps different volatility targets.

    The general pattern is a short sharp peak, followed by several years of drawdowns.  You spend most of your time under the high-water mark.  So a lot also depends on when you enter.

    The correlation coefficient of each fund's monthly returns (log difference) to the SG Trends Index was 0.6 to 0.8.  So they are all doing the same thing.

    You might say that starting in 2000 just before the great Nasdaq crash puts trend following in a particularly good light.  Lets pick another date at the start of 2003,  which is one of the S&P's bottoms:



    The percentage increase and CAGR for those funds active the entire period:


    Even here, a worst case scenario for trend following, the SG Trends Index still gives 5% returns.

    Risks

    There are 2 main risks.

    First, drawdowns are long and large, even for funds with high returns.   Look at the table here - its from 2012, after which there was another year of drawdowns!  Can you live with this?  Easier said than done.

    Second, sometimes a fund's rules just stop working, as the market changes.  For example, the original rules used by the famous turtle traders gave a CAGR of 216% from 1970 to 1986, but were flat from 1986 to 2009.  From 2003 to 2006, the highly successful Dunn Capital (in the graphs above) had a drawdown of 50%, while other funds rose.

    Fees

    Fees are very high, most funds charge 2 & 20.  Or more.  High minimum investments mean they are not available for retail investors.

    Retail investors can find a lot of feeder funds which will allow you to invest in the Big Boy's funds. But they typically use swaps to gain exposure to the underlying fund's after-fee performance.  This means that the underlying funds' performance fees are hidden - often not disclosed.  On top of this the feeder fund has a management fee (typically 1-2%) plus a swap feee (typically 0.5%).  They're charging money for nothing!  And the swaps may be worthless if the banking system comes under extreme stress, like in 2008.

    Morningstar covers a couple of systematic trend following funds which charge low fees - around 2+% total.  They're available through Schwab with no front loading fee.  But can only be bought by US residents.

    Since most trend following funds do the same thing - there are only so many ways to 'follow a trend' - fees are an important criteria.  I think this space will become more commoditized in the future, though fees will never be as low as index funds.

    Other Factors

    Many large funds concentrate on bonds, which are more risky now in a zero interest rate environment.  See the last 7 slides by Andreas Clenow here.  Safer to buy into a smaller fund which can trade a larger range of commodity markets.

    Summary

    Its worthwhile buying into a diversified systematic trend following fund, not just for 'diversification' or 'non-correlation', but because the long term returns themselves are worthwhile.  Most years are down years - be prepared to suffer.  As always, there's a bit of luck in choosing a fund - hope that it dosen't suddenly stop performing after you buy it.

    I don't live in the US, so couldn't find anything to buy.  Shit!

    Checklist for buying into a Trend following CTA fund:


    • Fees. 2+ % all-in seems reasonable.  Avoid swaps.
    • Fund size.  Probably between 1bn and 20bn.  Large enough so it wont close.  Small enough that it can trade less liquid commodity markets, and is not forced to trade bonds in a ZIRP environment. 
    • Correlate its past monthly performance against the SG Trends Index to check its really doing trend following.

    Trend Following: Part One

    What is it?

    "The core idea of Trend Following is extremely simple...Wait for momentum to build in one direction and get on the bandwagon.  Expect to lose about two thirds of the time and so make sure your winners can pay for your losers and leave enough over to cover the rent." (Clenow)

    In other words, buy after prices start moving up, sell after they start moving down:


    The rules used are simple, for example:
    • moving average crossovers above, 
    • channel breakouts
    • "buy when the price has spent 5 days above the moving average", etc.  
    You may also have an overriding rule to decide "market direction" first, and only take the trades in that direction.  For example:
    • based on a 200 day MA.  
    • For the stock market - based on macro economic data.  
    • For a currency - based on its strength compared to all other key currencies.


    Key Components of Trend Following Systems

    Back Testing

    Rules are back tested against old data to be chosen for the system.  You must know computer programming.  The process is harder than it sounds - there are pitfalls like over-fitting. The book Systematic Trading by Robert Carver covers these.

    After testing, you start the system in real life and hope it keeps working.

    Suffering

    60-70% of trades fail.  These should be made up for by rare winners.  You must systematically take every trade, you can't start second guessing which ones will win.  

    Individual markets often have long periods, sometimes years long, where they are trendless, like soy from 2009 to 2011.  Even after bleeding for years, you need to take every trade.  After eight, nine, ten, eleven, twelve trades in a row lose, you still have to take the next one.  Hard to do, unless you enjoy pain.

    Position Sizing by Volatility

    Unlike investors, Trend Followers measure risk by price volatility.  Specifically, volatility from the recent past is assumed to be close to volatility in the near future.  Potential loss is measured based on this volatility and the stop loss level given by your rule.  This should be limited to between 1% and 1.7% of your capital per trade.

    Potential return is also measured by volatility (again with the potential profit given by your rule). More volatile instruments require a smaller position, less volatile ones require a larger one (or maybe leverage).

    You shouldn't trade instruments where past volatility is artificially constrained e.g.:
    • Pegged currencies, e.g.: trading CHF when the Swiss government removed the peg --> you get blown up.  Maybe your brokerage too.
    • Going long on bonds in an low interest rate environment: Upside is limited as interest rates can't fall much further.  Downside will explode once rates move up.

    Diversification

    Trend followers typically trade 30-40 futures markets at the same time, spanning commodities, currencies and bonds.  The large number of markets is required because most markets are usually trendless. Adding new markets decreases your risk and increases your returns at no cost.

    The problem with exchange traded futures is that one contract size is large.  Clenow suggests you need a minimum of USD 1m to start trading safely.

    Yeah...if I had a million, would I spend my time implementing a Trend Following System?


    May not work on stocks

    Trend following may not work on stocks, as they are more volatile than futures.  Stock markets are highly correlated, and become more so when the SHTF, like in 2008.  So a trend following system in different stock markets is not diversified.  Also, vicious short squeezes will kill a simple automated system.  A systematic trend following system dealing with stocks will probably be long-only.


    What Next?

    The main benefit of a futures-based Trend Following system is to provide diversification, in particular, they tend to do well when stock markets do badly.

    If I was to stick to equities-only, to avoid the high capital requirements for exchange-traded futures, a trend following system may be useful as a counterpoint to value investing. When the market is high - like now - and buying and holding is too risky, a growth/momentum strategy with a cut-loss could gain exposure to the market with limited risk.  So it gives me a way to trade when I'm no good at discretionary trading.

    Next, I'll look into whether I could build my own system, or buy into a fund.

             

    Books and Websites


    1. Trend Following by Michael Covel: The book that popularised it.  Well written and entertaining, but lacking information.  Read if you're bored.
    2. Following the Trend by Andreas Clenow.  Describes what its like to implement and follow a system through his experience as a fund manager.  Well written, clear and concise, it is non-technical and an easy read.  An excellent first book for building a system - also see his writings online (1) (2).  Anyone buying into a TF fund should also read this, to discover what TF funds do, how they work, and what you're in for.
    3. Systematic Trading by Robert Carver.  More technical that the previous book, it goes into more detail on why Trend Following works, and common pitfalls in building a system.   I usually skimmed each chapter several times, first to determine what he is trying to do, then how he is doing it.  Its still well written, clear and concise, with the occasional dash of humour.  I think Part One of the book ("Theory") will be useful to any investor/trader.
    4. Au.Tra.Sys blog: Still digging through all the stuff here; useful for anyone building a system or buying into a fund.

    Singtel

    A quick look at Singtel.  I like them because their revenues are recurring, and they are in a markets which are a natural oligopoly.  Was attracted by their high margins - in 2015 operating margins from Singapore and Australia (after tax) were 21% - high for any industry and surprising for a utility or "dump pipe".  

    The stock price has dropped recently.  Based on their earnings/cashflows, at what price would I buy?

    Segments

    Singtel is a holding company.  FY 2015 EBIDTA (ending March 2015) is broken down from:
    • 26% from Singapore.  Singtel is the market leader and incumbent.
    • 29% From Australia.  2nd largest operator.
    • 47% from regional associates and JVs, when broken down:
      • 9% AIS (Thailand)
      • 6% Globe (Phillipines)
      • 21% Telkomsel (Indonesia)
      • 10% Airtel (Africa, India and Bangladesh)
    Overall about 2/3rd of revenue and profits are from consumers, the remaining from commercial.

    Cashflows

    Their business model is to use cashflow spun off from existing businesses to buy new businesses.  They have to balance this with paying out dividends to shareholders, and capex requirements to maintain and expand their networks.

    CFO is mostly from Singapore/Australia:


    CFI (outflows) are comfortably below CFO:


    The largest part of CFI is buying Property, Plant and Equipment, which is quite steady over the years.  Acquisitions vary:


    The dividends have been generally covered by cashflows, but this may be a problem going forward:


    Risks

    The main risks are:

    Currency fluctuations

    Page 108 of Singtel's March 2015 Annual Report gives a Sensitivity Analysis:

    I'm not sure about this.  The Telkomsel number is just 10% of their profits.  And I can't make sense of the Optus number: Optus operating income was SGD 2853m in FY2015 (p2 of Appendix 1):


    How can a 10% weakening of the AUD result in a less than 10% weakening of results?  Furthermore, Optus' CEO Allen Lew has been quoted saying "Our suppliers bill us in US Dollars".  The Sensitivity Analysis probably understates the impact by including the effects of currency swaps.

    I'm expecting the AUD to drop another 20% vs the Sing Dollar from now (30% from the time of the 2015 results).  We are halfway through a decade long commodity decline.  By my calculations, assuming 30% of Optus' expenses are in USD, this would give in a 42% decline in Optus' SGD profit! (vs 2015 results)

    Competition

    Singtel's margins were stunning 10 years ago, but since then have consistently fallen to be similar with Optus:


    IDA has announced intentions to allow in a 4th Mobile operator.  I believe the market is too small to support one.  The previous time this happened, Virgin Mobile closed after 9 months.

    New Industries

    There's a risk from Singtel moving into different industries (e.g.: cloud hosting, security) which are different from their core industry.  These industries are usually a lot more fragmented and fast moving than rolling out telecoms infrastructure.  I don't think GLCs can compete in fast-moving, unstructured industries that rely on a first-mover advantage and network effects.  These are the guys you watch Netflix view Facebook over - they can never be Netflix or Facebook.  Better to be a dumb pipe.  For example, why did they buy HungryGoWhere?

    Conclusion

    I like them because they have recurring revenue/profits, in an oligopolistic industry with some barriers to entry.   Not cyclical: their revenues/profits did not fall in 08/09.  And with Netflix and Cloud computing, the long term trend is for more and more mobile, home and office data usage.

    The biggest risk is currency.  I'd wait for the AUD to drop further, or for the market to factor it in. People forget it was 20% below the SGD for several years in the 1990's and early 2000's - commodity cycles are long.  As a rough guess: factoring in a 40% decline in Optus' profits and 30% decline in Telkomsel's profits from FY15 levels, I get profit reduced by 38%, giving a share price of  $2.25 at 15X earnings or $1.80 at 12X earnings.

    Rickmers Marine

    Rickmers Marine

    A REIT-like structure, holding and leasing 16 panamax container vessels (3400-5000 TEUs). Their fleet is new: all but one vessel was built in 2007 or later, and they have a 25-30 year lifespan.

    Rickmers stock price has plunged after it suspended dividends, due to lower revenue from declining rates.  How much of this is already built into the share price?

    First off, Rickmers has a loan covenant waiver that they need to extend, due end of this year.  If they can't, all bets are off, and they'll have to sell vessels.

    If they extend, then we value Rickmers by its ability to generate free cashflow and pay off debt.  Or maybe just survive.  Here's the relevant 3Q15 numbers for back-of-the-envelope calculations .

    Income/Cashflows

    • Revenue 27m
    • Depreciation: 8.7m
    • Vessel operating expenses: 9.6m
    • Misc fees/expenses: 0.9m
    • Finance expenses: 3.3m

    Vessel operating expenses seem to be pretty constant: they vary by at most 10% over the past 8 quarters.  Future revenue and finance expenses are the two big moving parts here.

    Revenue has dropped as their fleet's long term contracts have expired. 11 vessels are now on short term contracts:

    Three vessels we re-leased this quarter at around USD $6200, which is the market spot rate.  This rate has dropped sharply recently, and is now at the GFC levels of 08/09:

    So everything depends on the rate.  In their 3Q conference all, Rickmers' management states that this rate is just above cash breakeven.

    Container Shipping Outlook

    Depends on demand and supply.  I can't find any optimistic numbers on the container shipping market:

    a) Bimco (Nov 2015): 
    • Supply: Estimated new supply exceeds demolitions for the next few years:
    • Demand: In our last report we discussed if a potential gap in the market was the reason for 6-12 months’ charter rates for ships sized 1,000-4,250 TEU to significantly increase over the first five months of 2015. Today we can see half of the gain is now gone, and the rise in time-charter rates seemed to be more of a short-term imbalance rather than a long-term improved market.
    • In the 3,000-4,000 TEU segment...There is still more than sufficient supply of tonnage within this segment during the remainder of the year so we expect the rates to remain stable in the USD 6,000's depending on the exact vessel design. 
    c) Rickmer's 3Q conference call:
    • More than 30 vessels are currently idle in Asia and ready to sail now.

    Another trend is that new container ships are far larger (up to 20k TEUs), in a bid to drive economies of scale.  Some of the 3000-4000 TEU ships are now being used as feeder vessels (including the Laranna Rickmers, leased to Simatech).

    Debt

    They have:
    • 325m bank loans (USD Libor + 1.7%).  46.5m short term, 279m long term.  With 50m cash to offset the short term loan due.
    • SGD 100m (~USD 80M) "Series 1 Notes" issued May 2015 S100m: 8.45% PA, matures May 2017.  Currency risk unhedged now.
    A large chunk is due in 2017: 


    Their USD bank loans (in Q3 around 2+% interest) will have to be refinanced in 2017.  I would expect interest rates to be higher in future, lets say 3 or 4 fed hikes.  About 1% or so, giving a rate of 3+ percent (if they can refinance under the same conditions....the covenants).

    But the loans come with restrictive covenants, and they may choose to refinance by their MTN program instead (of which only 100m out of 300m has been used).  This has a high interest rate at 8+%, and there is also a refunding risk every 3 years.  (I assume they would hedge currencies if they take on more SGD debt).

    I calculate that, if the market rate stays at $6300/day, by the end of 2017, they need to refinance USD 135m plus SGD 100m.  Assuming they use the MTN and get the similar rates, thats about USD 17m per year interest.  Or 4.3m a quarter, an increase of 30% over 3Q15.  Manageable.  

    Can they survive?

    Probably.  It all depends on the rates.  If they plunge below cash breakeven by 2017, Rickmers may not be able to secure financing on favourable terms.  Or on any terms at all?  Either demand needs to recover, or ships need to be scrapped.

    Historically, have container rates gone below cash breakeven for long periods before?  Need to do more research.

    As value investors, how would we play a cyclical industry?  Wait for the industry to bleed for a while... my guess is - for long lived assets it will take years.  Then buy companies with strong balance sheets and cashflows, if any.  Easy to say, hard to do.

    Rolls Royce: Aircraft and Engine retirements

    Roll's recent profit warning was due to the transition from old engines to new one.  Old planes are being retired, reducing maintenance income, while Rolls is still waiting to ramp up production in new engines.

    I need to get some idea of the numbers of aircraft being retired in the future.  Is there more to come?


    First, lets look out the different aircraft models based on range and payload:



    Ignore Narrow body aircraft at the bottom left, which are irrelevant to Rolls.

    Jumbos, in the top right, are large 4-engined planes.  They are now a niche product: for polar flights, freight, or busy slot-constrained airports.  They are only profitable when full, which is risky for airlines as they can't scale down.  Passengers also prefer greater frequency with smaller planes.  B747s are being phased out for passenger use, and the is A380 only successfully used by mid-east carriers.

    Soonest to be replaced will be the B747s and A340s, due to their fuel-guzzling 4 engines.  Followed by the B757, now also out of production.  They will be replaced by the B787, A350, future B777X and future A330neo.

    Its not a 1-1 replacement.  Larger aircraft are more profitable (when full), but more risky to operate.  For example: an A350 gives better per seat fuel milage, but may be harder to fill, so could be substituted by 1.x B787's, allowing the airline to scale down the route when necessary.


    How long do planes last for?  The lifespan of a Wide-body averages 25 years.  It depends on the individual plane's model and milage - some last 35 years.  Freighters tend to last longer.




    (Source: Avolon white papers 2015 and 2012.


    To estimate the number of aircraft retiring, I searched the www.airfleets.net production list for all aircraft in the "Wide Body" and "Jumbo" categories above.  I only took currently 'Active' aircraft, ignoring 'stored' ones and did not distinguish between passenger or freight (or the occasional military).  Then I added 25 years to the each plane's first flight year, to estimate when it would retire.  The resulting graph gives the number of Rolls Royce engines due to retire in red and non-Rolls engines in green:

    Again, it is number of engines, not planes.  And its only a rough estimate, as each plane could retire up to 10 years earlier or later.  So we can't predict the timing of any more earnings surprises in the future.

    What we can tell is:
    • The numbers expected to retire are around 50 engines from 2014-2016, 150 engines from 2018-2022, and 150-200 engines from 2023-2026.
    • The predicted retirements match favourably with engines coming on line in the next few years.  Around 780 A350's are on order, but their rollout is constrained by Airbus' production rate.  Its currently 3 A350's per month (i.e.: 72 engines per year), expected to raise to 10 per month (240 engines per year) in 2018.  And maybe 13 planes/month (or 312 engines per year) after that.
    • Plus another 350+ B787 planes (700+ engines) from the current order book, lets say over the next 9 years.
    Based on the order book and the projected number of engines retiring, Roll's problems of retiring engines are temporary.  In the long run, there is no evidence that the number of engines maintained will drop, and it will probably increase.

    Bought Rolls Royce

    Bought another 2073 RYCEY ADRs, at $10.4255.  Total cost USD 21,621.

    Thats priced at roughly 13X earnings.  Rare to find inexpensive blue chips in year 6 of a bull market.  Now I have a full position in this counter.

    Now around 85% in cash.

    Bought USD

    In late 2011, I sold my Perth property and converted the money to SGD, because:
    • Commodity booms are cyclical, and we were 9 years into one.
    • The property's price had risen 4 times in 14 years, (non-mining) wages had only risen 50-100%.
    • I was expecting a recession.
    The last didn't happen, and I was 2 years early, but the decision proved correct:



    Today I converted a significant amount of SGD to USD.  This decision is a lot less certain.

    Holding SGD is a little bit of a risk (not a lot), as its lumped with Emerging markets.  The risk is if China devalues the Yuan significantly, due to capital flight and the unwinding of the carry trade puffed up since 2008 by endless rounds of QE, and they start to lose control (1) (2) (3).  But holding USD is a risk if the US economy falls or if we get QE4....QE for-ever....

    I don't know what will happen - Nobody knows nuthin'.  But its too much of a risk to hold all my money in SGD, better to balance a little.  Maybe I'm right.  Or maybe I'm the last sucker to make this trade.

    Now I'm holding:


    In the big picture, I'm still holding cash waiting for the stocks to fall.  And still avoiding commodity currencies like the plague.  Not trying to make money yet, just trying not avoid too much risk.
