Note that 2000 was a losing year because of the choice of the starting date of the backtest the system entered in a long trade near the top of the long uptrend of the 1990s. The only other losing year is 2011 with a -11.1% return. For 2008, the system returned 15.5%.

Below is a table of monthly results in the case of QQQ:

Again, in the QQQ case the first year is negative by virtue of the choice of starting date of the test but although there are more negative years, the losses are much smaller than in the case of SPY and 2011. In 2004 the system had a very small negative return of -0.6% and in 2006 and 2009 negative returns in the vicinity of -3.5%. But unlike the SPY system, it shows positive performance for 2011 and higher returns for 2010 and 2012.
