Jeff Gundlach, founder of DoubleLine Capital, warned on Monday of the extremely high valuations of the market by historical standards amid the risk of rising inflation.
"We are here with extremely high ratings and it is supported by massive impulses," Gundlach told CNBC's Scott Wapner in the "mid-term report".
"If you go back four decades of stock market data, there are a lot of valuation metrics that are in the top 1 percentile of overvaluation. Of course, what keeps them going is the Fed, with rates at zero and promises to stay at zero," added Gundlach . This "enables ratings to be record-breaking."
"Historically, when momentum and sentiment indicators are this high, the market is facing a period of consolidation," said Mark Hackett, chief of investment research at Nationwide.
Stocks have had a strong week of gains, pushing all three major averages to record highs. The main averages shook off the turmoil in the U.S. Capitol that led the House Democrats to launch an impeachment article against President Donald Trump on Monday for inciting the attack. The lower chamber plans to vote on the article sometime this week.
Monday's outperformers were the ones most sensitive to economic growth, such as banks, retailers and certified small caps. Last week, President-elect Joe Biden promised a stimulus package that will be in "trillions of dollars".
The small-cap benchmark Russell 2000 lost 0.03% on Monday.
