WMT Trading System (Daily)

For the period 1/8/13 to 2/11/15 the trading strategy returned $13,608 on an initial investment of $10,000. Buy and hold returned $3280. At the bottom of the graph are the signals. In this case the buy signals show good reinforcement, generally a buy signal is followed by several other buy signals. Sell signals show little reinforcement. Red and green bands show when the stocks were held long (green) or short (red).

WMT Daily. The tables show the annualized return of the trading strategy (50.8%) vs. buy and hold (14.7%) for the 2 year period 1/8/13 to 2/11/15. Drawdown was 6.2% vs. 10.5% for buy-hold. You can also see how you would have fared going only Long or Short or short-and-hold. The lower table describes the signals and the strategy in detail. The Long and Short strategy is described which requires holding the stock long or short at all times, however you would also have made a profit taking just the long or short side.

These graphs show how the return varies with changing the parameters of the algorithm. Note that for a sell point of 0%, all buy points to beyond 10% were profitable. However the algorithm was highly sensitive to changing the sell point, which had to be between 0% and 0.5% to give significantly advantageous returns. If outside of this narrow range, the algorithm was only as good as buy-hold.

The Life graphs show how the returns look over four different time periods. In general it is best to look for systems with consistent returns. For this strategy, all four time periods showed returns better than buy-hold.

WMD Daily. This shows how the return varied when the buy and sell points were varied. Notice the sell point range is much narrower that the buy point range. The algorithm only worked for a very small range of sell points.

  2. Note, the above analysis erroneously assumed commissions of zero. When $7 commissions are accounted for the annualized return was 49.5% not 50.9%. Since posting on 2/12/15, the strategy has almost tracked the buy-hold of WMT exactly, with a loss of 23% vs. buy-hold of 22%.
