Economics Apple’s coronavirus warning just shaved $34 billion off its stock market value By News Desk Posted on February 19, 2020 1 min read 0 0 4 Share on Facebook Share on Twitter Share on Google+ Share on Reddit Share on Pinterest Share on Linkedin Share on Tumblr A string of US companies has been cautioning investors that first quarter sales could take a hit from the spread of coronavirus. Apple (AAPL) just made it all more real. The $1.4 trillion company put out a surprise investor update on Monday, warning that it no longer expects to meet the revenue guidance provided last month. Notably, the company isn’t just concerned about a hit to demand for Apple products within China — which had been expected, since all its stores there have been closed. It also faces issues with iPhone production. Such supply chain issues have been a chief concern for economists tracking broader fallout from the new coronavirus. “Work is starting to resume around the country, but we are experiencing a slower return to normal conditions than we had anticipated,” the company said.
