On average the S&P increases by 10% annually. Across 250 trading days, it increases by 0.04% daily on average. So his picks do not beat the market on average.

- vannevar 5y agoYou're right, that seems to contradict the author's assertion that Cramer's 1-day performance beats the S&P 500 by a factor of ten. Maybe he made a simple math error somewhere---forgetting to adjust the daily SPY return by 10x when converting the units to a percentage, perhaps? Multiplying the stated .003% daily return by 250 yields .75% annual return, which seems wrong. Pretty sure the average annual S&P return from 2016-2021 was higher than that. Investopedia says the annual return is around 10% since 1957.

- vannevar 5y agoThat doesn't explain why the 1-day SPY Buy row is 10x the 1-day SPY Positive Mention row---they should be about the same, as they are in the other rows, since they're essentially random samples over the timeframe.
