Why Twilio, Zoom Video, and CrowdStrike Stocks Crashed on Monday

The stock market began giving back some of Friday's gains on Monday, and as of 12:40 p.m. ET, the tech-heavy Nasdaq was down 1.1% -- with significant deviations. Three tech stocks of particular interest today are videoconferencing app Zoom Video Communications (NASDAQ: ZM), down 4.6%; cybersecurity company CrowdStrike Holdings (NASDAQ: CRWD), down 5.7%; and cloud communications platform Twilio (NYSE: TWLO), down 9.4%. Let's start with the big picture: Inflation and interest rates are both up, which makes future profits less valuable and raises the cost of taking on debt while waiting for profitability to arrive.
