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

The shares traded at $71.77 each as of 1:43 p.m. in New York, a 441% 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.
