description: "Due to a 10% intraday drop yesterday, the U.S. Securities and Exchange Commission's Rule 201 (also known as the "Uptick Rule" or short sale restriction) was triggered and took effect today. Restriction mechanism: After the restriction takes effect, investors can still short the stock, but they cannot actively sell at the current best bid price or lower. Short sellers can only place limit orders at an "uptick quote" above the current best bid price, passively waiting for a buyer to execute the trade.Effective time: The restriction is not only effective on the day it is triggered but also continues until the close of the next full trading day. The first screenshot clearly shows that HIMS's short sale restriction lasted from 09:32 EST on Feb 24 to 20:00 on Feb 25 (i.e., after-hours trading ends).$Hims & Hers Health(HIMS.US) $Defiance Daily Target 2X Long HIMS ETF(HIMZ.US)"

- **小袁边走边吃 · 2026-02-25T15:46:34.000Z**: Is this the reason for today's rise?
  - **ST欧阳昆汀** (2026-02-25T15:48:30.000Z): Not sure, let's observe again tomorrow.
- **老板不要放葱 · 2026-02-25T15:42:36.000Z**: So it's about restricting short selling?
  - **ST欧阳昆汀** (2026-02-25T15:44:48.000Z): You can short this stock, but you cannot actively sell it at the current best bid price or lower. Short sellers can only place limit orders at a "rising quote" higher than the current best bid
  - **老板不要放葱** (2026-02-25T15:49:03.000Z): Once that time limit is up, won't it just pounce right back?
  - **ST欧阳昆汀** (2026-02-25T15:51:17.000Z): Not sure. So let's wait and see when the market opens tomorrow. But you bottom-fished at 14 yuan yesterday, you should be able to get some meat.🍖
