DAVID EINHORN: 'We Are Witnessing Our Second Tech Bubble In 15 Years'

Hedge fund manager David Einhorn, who runs Greenlight Capital, says that we're witnessing a tech bubble, CNBC reports citing his fund's quarterly investor letter.

"Now there is a clear consensus that we are witnessing our second tech bubble in 15 years. What is uncertain is how much further the bubble can expand, and what might pop it," Einhorn wrote in the letter.

He also added that Greenlight is short some "high-flying momentum stocks" in the tech sector, according to CNBC.

Those short positions weren't disclosed in the letter, the report said.

Einhorn, who is famous for his prediction of the Lehman Brothers collapse, also detailed a number of stocks in the letter that he's long as well as some positions he's exited during the first quarter of this year.
