Firefly Aerospace soared for a third consecutive day on Monday, jumping 16.02 percent to close at $28.60 apiece after officially joining the Russell 2000 Index.

The company was among the 18 firms added to the benchmark, which also triggered its inclusion in the Russell 3000 index. The recomposition officially took effect on the same day.

Firefly Aerospace Inc.’s (NASDAQ:FLY) inclusion in the said indices is expected to open doors for greater exposure among institutional and foreign investors.
