Webull Corp. shares more than quadrupled on Monday after the online brokerage went public last week by merging with a blank-check vehicle.

The shares closed at $62.90, a 375% increase from the closing price in its first day as a public company. Webull began trading Friday after merging with SK Growth Opportunities Corp., a special-purpose acquisition company. A subsidiary of Korean conglomerate SK Inc. was the anchor investor in the SPAC’s sponsor.
