 Shares of electric delivery-van maker Workhorse Group NASDAQ: WKHS were trading higher on Monday. The company holds a roughly 10 stake in electric-pickup start-up Lordstown Motors, which revealed plans to go public via a reverse merger with DiamondPeak Holdings NASDAQ: DPHC before the markets opened on Monday. Not today: The deal to take Lordstown Motors public will dramatically increase the value of Workhorses stake in Lordstown and in time give it a cash flow from royalties.
