Each point on each curve marks the performance value in percent gain over the prior six months. The green pole rises from the week dated September 5, 2003. This week is at or near the peak six-month performances of both the Winning System and the market itself (SP500).
However, from that date forward until July 9, 2004--ten months--the first red pole, the system's margin of beating the market continually narrows. During the last three months, the system performs worse than the market!
This happened again during the latter half of the one-year period marked by the two red poles when the system became both negative and well below market performance.
These impressions do not jibe well with the landscape impressions that existed at the time of the bars. But I do not believe that would have deterred you from signing up then because the landscapes you would have seen were all very favorable at the time, showing +45% vs -8% for the system vs the market at the first pole and +69 vs +3, +67 vs 0, and +108 vs +9 at the next three poles.*
