Firefly Aerospace's ( FLY) stock is sputtering, just one day after its trading debut, when enthusiasm for the new listing sent shares soaring. The space company's stock was down 13% to about $52 Friday afternoon, wiping out more than half its gains in its first day of trading yesterday.

Firefly Aerospace, which successfully landed on the moon in March, is went public today under the stock ticker symbol FLY. It opened at $70 a share, 56% above its IPO price.

After several big IPOs including Figma last week, the IPO market stayed hot with Firefly Aerospace, which is now approaching a $10 billion valuation out of the gate. I would categorize space as one of the hot sectors, along with artificial intelligence, crypto, and quantum computing, that investors can't seem to get enough of.
