Physician, hedge fund manager and value investor Michael Burry has let out a tweet that appears to warn investors of further erosion in stocks.

What Happened: Burry said Wednesday that from “Top to bottom” Microsoft Corporation (NASDAQ:MSFT) shares traded 5.2x its shares outstanding by 2002 and 3.3x by 2009, while it has traded only 0.5x so far.

Amazon.com, Inc (NASDAQ:AMZN) had traded 5.7x by 2002, 6.6x by 2009 and 0.9x so far, while JPMorgan Chase & Co (NYSE:JPM) traded 3.0x by 2002, 5.9x by 2009 and 0.7x so far.

Why It Matters: The timelines given by Burry — 2002 and 2009 — were preceded by market downturns in 2000 and 2008, respectively. 

While the dotcom bubble brought the markets down in 2000, there was a global financial crisis in 2008 that saw the bankruptcy of Lehman Brothers. 

Burry pointed to the rising S&P 500 price-to-sales ratio last month in another tweet. He is known for deleting his tweets but has been active on the social media platform lately.
