Billionaire investor Paul Tudor Jones said Monday that the high stock-market valuation makes him uneasy and warned the Federal Reserve could be adding to financial instability with its aggressive policy stance.

The hedge fund veteran told CNBC's Andrew Ross Sorkin on "Squawk Box" that the stock market appeared richly valued relative to the broader economy, comparing it to the top of previous market cycles before significant corrections in recent decades.
