Sidus Space Inc is trading 14.5% up today at $5.08 as the stock rebounds following confirmed inclusion in several Russell indexes.
- The company is set to join the Russell 3000, Russell 2000, and Russell Microcap indexes, a move expected to drive significant institutional and index-fund buying.
- Today's gain marks a sharp recovery from a 10% drop in the previous session, which was attributed to profit-taking despite the positive index-inclusion news.
