Shares of Hyperfine jumped after the company said it would join the Russell 3000 Index and the Russell 2000 Index.
The stock was up 9.7% at $1.64 on Tuesday. Shares have now gained 67% since the start of the year.
The health technology company said before the opening bell that it is expected to join the broad market Russell 3000 and the small-cap Russell 2000 at the end of next month's rebalancing of the indices.
Many exchange-traded funds and mutual funds track the Russell 3000 and Russell 2000, meaning Hyperfine's addition would create a wave of automatic buying into those shares from fund investors.
