The stock market took a significant tumble on Monday, with the Dow closing down more than 500 points, due in large part to investor concerns over the tech sector and a strengthening dollar, according to CNN Business.
> Apple (AAPL) fell 5% after supplier Lumentum cut its earnings and sales forecast because of weak demand, and JPMorgan cut its target price on Apple's stock. That weighed on other technology stocks, including Amazon (AMZN) and Tesla (TSLA) -- down 4% -- as well as Facebook, which fell 3%. Google (GOOGL), Netflix (NFLX) and Microsoft (MSFT) were all down more than 2%.
> The strong dollar also weighed on stocks. The US currency surged to a 16-month high because investors fear the European economy could stall if no Brexit deal is reached this week. Prospects of another rate hike from the Fed next month have also helped lift the dollar. The rising dollar is a signal of a strong economy, but it hurts sales and profits for American companies that do business overseas.
