Stocks with at least 3 independent periods, ordered on an evidence-weighted median: each stock's median is pulled toward the S&P 500 typical value in proportion to its uncertainty, so a lucky handful of events cannot top the list. Confidence counts independent holding periods (overlapping ones count once): High 20+, Medium 8+, Low 3+. Median and average gain over the next week from the entry close; Up = share of events followed by a gain; vs SPY = median gain minus SPY over the same sessions. Ranks on the stock pages place each stock among the S&P 500 stocks. Small samples are noisy, and the past does not repeat on schedule. Not advice.
