NVDA · 2024-08-05 · 1h — cohort of 500 historical analogs
(485 with realized 5-day returns)
Distribution at 5 days forward:
median: −1.3%
p10 ·· p90: −11.3% ·· +6.8% (80% empirical band)
win rate: 44%
cohort_score: 0.31 (modest)
Features that separated winners from losers:

Summary: NVDA's 1-hour pattern on 2024-08-05 has 500 historical
analogs. The cohort's 5-day distribution is bearish-leaning
(median −1.3%, win rate 44%) — the historical record does NOT
show this pattern typically resolving bullish. Conditioning on
tight credit spreads and a bullish macro state would have
separated the outperformers within the cohort.
