None of these companies had any material news today; however, the combination of a higher-than-expected inflation report and weak earnings out of software peer DocuSign (NASDAQ: DOCU) was enough to send these growth leaders tumbling. Additionally, bad billings guidance from DocuSign on its first-quarter earnings release last night cast a doubly sour mood over the cloud software space. Although DocuSign's revenue beat expectations for the current quarter, up 25%, management expects only 6% to 7% billings growth this year.
