Buying Surge — Far More Than the Usual Amount

Updated: Aug 23, 10:40 AM ET

As of 2026-08-16, 54 stocks saw open-market buying over the last 7 days at least 10x their 52-week average.

The biggest jump was ENHA, at 574.8x the usual amount.

⚠ Recently listed stocks or those with limited trading history have a smaller baseline, so a single trade can produce an exaggerated multiple. We've flagged stocks with a typical weekly amount under $5,000 with a "Limited Data" tag — the API still doesn't expose how many weeks of history each stock has, so that part of the check isn't possible yet.

Glossary

SEC Form 4 transaction code P: an open-market purchase made by the insider with their own funds.

Option exercises (M), stock grants (A), and tax-withholding dispositions (F) are not counted as buys.
