The Leaderboard ranks members according to a combination of scorecard performance, number of recommendations and time-frame.
A member must have recorded some activity on Strawman within the past six months to rank on the Leaderboard.
The performance of a member's scorecard is the main consideration, but this is adjusted to account for diversification and longevity.
Why do this? Due to short-term volatility, the potential exists for an investor with a single recommendation on a speculative stock to post a higher scorecard return than someone who has issued dozens of recommendations over several years. The former is largely a function of luck, while the latter is far more challenging and reflective of investing acumen.
Without going into specifics, the fewer the recommendations on your scorecard, the more your return is penalised. There is no penalty once you reach 10 recommendations, and there is even a small and increasing multiplier after this threshold.
Similarly, the shorter the period over which your scorecard has been active, the more your return is penalised. The penalty diminishes with time, and disappears after 12 months. Members receive a modest but increasing multiplier after this threshold.
Note that closed positions still impact your recommendation count and longevity.
In short, if you want to rank on the leaderboard, build a market-beating scorecard, over a meaningful period of time, with a decent number of individual recommendations.
