The U.S. stock market started the new month significantly overvalued based on Berkshire Hathaway Inc. (BRK.A, Financial)(BRK.B, Financial) CEO Warren Buffett (Trades, Portfolio)'s favorite market indicator.

U.S. indexes start new month with a bang, led by top Berkshire holding Apple
On Monday, the Dow Jones Industrial Average closed at 31,535.51, up over 600 points from last Friday's close of 30,932.37, boosted by stocks like Boeing Co. (BA, Financial) and Apple Inc. (AAPL, Financial).
Buffett mentioned in his 2020 annual shareholder letter that he and Charlie Munger (Trades, Portfolio) view Berkshire's holdings of marketable stocks as "a collection of businesses":
"We do not control the operations of those companies, but we do share proportionately in their long-term prosperity."
The "Oracle of Omaha" said that Berkshire started buying shares of Apple for its main account in 2016, expanding the position to over 1 billion shares on a split-adjusted basis by the third quarter of 2018. Despite selling approximately 6% of its stake during the fourth quarter of 2020, Berkshire now owns over 5.2% of Apple's total shares outstanding. Shares occupy 43.61% of the insurance conglomerate's nearly $270 billion equity portfolio.
