Robust Strategy Design
We elaborate strategies starting from fundamental and technical analysis research. We do our best to detect and avoid curve-fitting. The period of simulation is as long as possible depending on data availability, most of the time since January 1999. This period covers all conditions and two market cycles.
The Luck Factor
Luck does exist. With the same probability to win (p) and the same average win/average loss ratio (w/l), your account may experience very different possible futures depending on the sequence of gains and losses. Example with w/l=1,4 and p=50%:
We select only strategies with a focused beam of possible paths, like this one:
To evaluate robustness, we use a probabilistic indicator taking into account the data sample size. Every model is an approximate representation of a real phenomenon. It is impossible to reduce the risk to zero or to predict the future, but it is possible to detect when a strategy goes out of its normal limits.
Even a good strategy may have a 30% drawdown and stay negative during months. It is easy to imagine, but harder to live. It is better to invest less capital than giving up under pressure with a good strategy. Without a long term vision, the short term makes no sense.
