From mounting geopolitical tensions to the Ebola outbreak and Washington gridlock, there are more than a few reasons to reduce one's exposure to the stock market, investor Roger McNamee told CNBC on Monday.
"It just seems to me that there is a lot of chaos in the world and the rate of chaos is increasing a lot, and to me, that just makes me incredibly nervous," McNamee, a managing director and co-founder of venture capital firm Elevation Partners, said on "Squawk Alley." "It doesn't change how I feel about individual stocks. What it does is it changes how much exposure to the market I want to have."
In turn, McNamee said he has taken "quite a lot of money off the table." Over the past week, he has reduced his exposure to equities by roughly a third, moving his money out of the stock market and into U.S. Treasury bonds.
"I don't understand how you can have so much chaos in the world and still have prices going up everyday," he said. "I think this is a really important time for people to ask themselves the question of how confident are they in the fundamentals of things they own and how confident are they that there's a happy ending this year for the economy and the stock market?"
For now, McNamee said he plans to sit on the sidelines "for a while until the dust settles."
