Even their cleanest calls trailed the market.
What “return vs sector” means
Across 28 bets, @markpinc's average call trailed its sector by 3.3% per month, each bet judged on its author's own timeframe (1 month when unstated, or as far into it as the data reaches) — t = -1.5, not enough to tell skill from chance.
t = -1.5 — the strength of the evidence. Above 2, there's under a 5% chance it's luck.
How the t-value works
Each call is one bet, scored by how much it beat its own sector (fairer than the whole market). The t-value is the average beat divided by its uncertainty:
Same-week, same-sector calls ride one move, so they prove less than fully independent wins — the 28 bets count as 26 effective ones. That's why the honest t is -1.5, not the raw -1.6. Full breakdown on the analysis page.

How we measured this · download the raw data
We pull @markpinc's posts, use AI to extract each call (ticker, direction, conviction), and backtest it against real prices. A call wins only if it beat its own sector over the month after — not just if the stock rose. Headline numbers use deduplicated bets.
