Facebook shares nosedived Thursday morning, chopping more than $100 billion from the company's market value, a day after a similar selloff caused by its earnings report that suggested growth at the social network was slowing.

Shares in Facebook, long one of the steadiest tech investments, collapsed by almost 20 percent in morning trading to $175 a share. The drop, which followed a nearly 25 percent free fall on Wednesday evening that wiped away roughly $150 billion in value, is among the largest ever single-day drops in market capitalization, the value of all of Facebook's shares added together.
