A sell-off started by Facebook Inc. led to losses across the indexes on Monday, March 19.
The Dow Jones Industrial Average dropped 1.35% to 24,610.91, the S&P 500 fell 1.42% to 2,712.92 and the Nasdaq Composite Index shrank 1.84% to 7,344.24.
Facebook's shares tumbled on March 19 as a growing group of officials in the United States and European Union called for investigations into the mishandling of personal user data by a political data analytics firm. The company disclosed on March 16 that it had suspended the accounts of British company Strategic Communication Laboratories and its political data analytics firm Cambridge Analytica LLC, as well as Christopher Wylie of Eunoia Technologies, for violating the platform's personal data policies.
That decline sparked a sell-off in technology stocks that quickly jumped to other industries, dragging most of them down.
