Contract doublers: catalyst discovery

Which tickers had option contracts gain at least 100% over the preceding five trading sessions?

A retrospective starting point for investigating catalysts. The appreciation has already occurred; listed contracts are evidence of past repricing, not entry candidates. Compares the same contract at the latest close and five trading sessions earlier, using closing bid/ask midpoints. A price move does not identify its cause or imply that it will continue. Both observations require positive, non-crossed quotes, a relative spread of at most 20%, and at least 100 open-interest contracts. Contracts expired before the latest session are excluded. Data through Oct 16, 2026 close. Descriptive only, not a recommendation.

Comparison: 2026-10-09 close to 2026-10-16 close, five trading sessions apart. Evaluated 115,037 contracts across 2,009 tickers. All qualifying tickers are listed, ordered by their highest contract priority. Up to five contracts per ticker are shown, highest priority first. Strike identifies the contract; starting and ending option prices are not published.

Priority points combine the five-session gain with a diminishing bonus for longer DTE (calendar days to expiration at the latest close). At the same gain, longer-dated contracts rank higher. Weighting applies before selecting the five examples; qualifying counts include every match. The 100% requirement is unchanged, with no minimum DTE. Points help order catalyst research; they are neither a probability that a catalyst occurred nor a trade score.
