Telegram boasts 500 million users, who share information individually and in groups in relative security. But Telegram's use as a one-way broadcast channel — which followers can join but not reply to — means content from inauthentic accounts can easily reach large, captive and eager audiences. For tech stocks, “the main thing is yields,” Essaye said. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. The Russian invasion of Ukraine has been a driving force in markets for the past few weeks. Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp.
