Cointegrated Stock Pairs: Top 30 August Vintage Post a Perfect Record in First Three Weeks of Live Trading Out-of-Sample

Cointegrated stock pairs

Pair Trading stocks involves simultaneously entering LONG (i.e. BUYING) and entering SHORT (i.e. SELLING) two “paired” stocks.  It has been shown to provide protection from market crashes, controlled risk, low correlation to the market averages and ability to generate significant and consistent returns.  Multiple recent research studies have demonstrated returns to be in the range of 2%-4% per month*, on a 4:1 leverage basis, over more than a decade.  Add in the use of Cointegrated Stock Pairs and the historical returns look even stronger**.

August 2020 Vintage Top 30 Early Performance: Live Signal Results vs. Previous Backtested Results

We launched a new vintage of Top 30 Cointegrated Stock Pairs after the close on 21 August 2020.  They have 63-day lookbacks and 2.50 Entry Stretches and 0.80 Exit Stretches.  Here are the backtest results that led us to select these pairs:

Cointegrated Stock Pairs

94% Win Rate, 4.1x Reward/Risk, profits of $71,659 in a year (at $10k/leg trade size).  Frankly those are some pretty fantastic looking backtest results.

However, as any seasoned system trader knows, in-sample and out-of-sample results are very different things.

So here are the out-of-sample results of the exit signals and open trades of the August 2020 Vintage in from 24 August to 15 September 2020.  These trades represent signals you could have traded live:

Eight exits, eight winners, a 100% win rate, for a total profit in the the first three weeks of $3,907 (assumes a $10k/leg trade size). Wow.

And the currently open positions:

are showing a mark-to-market PnL of $-191 as of yesterday’s close.

That’s a $3,716 net profit showing for the out-of-sample trade signals on the August Vintage Top 30 since their launch three weeks ago.  The account margin employed to hold eight trades open at $10,000/leg is about $32,000 (at 5:1 CFD leverage).  So the three-week return on imputed margin for the August Vintage is approx. 11.6% (before margin interest expense but after assumed commissions and slippage of 10bp per leg, per trade).  See disclaimer below.

Relative Performance vs. S&P 500: Over 15% Alpha Generation in One Month

Over the same three weeks or so period, the S&P 500 (SPY ETF) lost 0.8%.  Levered at the same level as the imputed margin return above (5:1 CFD leverage), that would translate to a -4.0% loss (before margin interest).  That implies the Top 30 generated an alpha (performance relative to the index) on margin deployed of 15.6% for the period.  We find that result quite spectacular.
