SemiAnalysis
SemiAnalysis published 59 pieces between 2026-05-01 and 2026-10-23, covering 20 tickers plus 7 macro pieces with no single ticker. Quant Data extracted 1,501 discrete claims from them, of which 31 were directional statements on a named ticker. Over the last 30 days it published 9 pieces, about 2.1 a week. These are counts of what was published, not a judgement of it.
Full-history audit result
SemiAnalysis is one of 3 sources (of 79 examined) that passed Quant Data's finance-influencer audit, which backtests every dated directional statement in a source's full archive against QQQ. Over 1,378 statements on 257 tickers from 2020-05-22 to 2026-07-07, the rule "first bullish statement, then hold" produced 57 trades with a 56% win rate and a median excess return of 9.3% over the benchmark. Method, caveats and the failures of other sources are on the audit page; the dated statements are pinned on price charts.
