買超過100檔持股不用擔心績效會不好，
因為我們並非亂槍打鳥，
而是從預期報酬率大於15%的入圍名單中選股。
100支以上持股的績效會穩定趨向15%年報酬率。
Buying over 100 stocks, there's no need to worry about poor performance because we're not shooting blindly. Instead, we choose stocks from a list of candidates with expected annual returns greater than 15%. A portfolio holding over 100 stocks will tend to stabilize towards a 15% annual return rate.
有人把績效不好歸咎於買太多檔無法照顧，
事實剛好相反，買越多支反而保護你不掉到更壞的結果。
樣本越大越趨近於你的勝率，
樣本小會大好大壞，最終以大壞收場。
Some people attribute poor performance to holding too many stocks and being unable to manage them effectively. In reality, the opposite is true: broad diversification protects investors from far worse outcomes. As the sample size grows, performance converges toward an investor’s true win rate. With a small sample, returns are far more volatile, swinging between outsized gains and losses, and often end in a significant drawdown.
