DocuSign shares rose almost 5% in extended trading after the electronic signature software maker announced it has hired an Alphabet executive, Allan Thygesen, to be its next CEO. CNBC reports: The announcement comes three month after DocuSign said its CEO for the past five years, Dan Springer, was stepping down. Like other cloud software companies, DocuSign enjoyed a wave of greater interest among investors during the Covid pandemic as consumers and corporate workers became more reliant on digital ways to sign documents. But the interest has died down. Notwithstanding the after-hours move, DocuSign shares have fallen 64% so far this year.
