Another day, another stock market setback for once high-flying technology companies, which have lost roughly $1 trillion in the latest stock market slide. Shares of the core group of consumer technology companies including Facebook, Amazon, Apple, Alphabet, and Netflix are falling again — contributing to the big indexes like the Dow Jones Industrial Average and the S&P 500 sliding into negative territory for the year. This collapse is thanks in part to rising interest rates that have investors looking for a more stable return profile than placing bets on high-growth technology companies.
