BYSI is trading 5% up today at $1.84 as the stock rebounds from selling pressure tied to its recent removal from a key Russell index.

  • The move follows the June 30 rebalancing event, which forced index-tracking funds to liquidate positions and weighed heavily on the stock's price.
  • Traders appear to be bargain-hunting in the thinly traded biotech name now that the index-related selling has been largely priced in.
  • The recovery comes amid mixed broader market performance, with company-specific flows currently taking precedence over macro news.
