By Manya Saini (Reuters) -Firefly Aerospace shares fell 11% in morning trading on Friday, in what was perceived as a normal market swing, but the space tech firm's robust debut highlighted renewed investor appetite for high-growth listings.

Firefly also boosted the size of the IPO. It will raise nearly $870 million from the stock sale. It is selling 19.3 million shares, up from an original proposal of 16.2 million shares. The stock will trade on the Nasdaq under the ticker symbol FLY.
