Warren Buffett’s Berkshire Hathaway revealed three secret stock buys and a reduction in its Apple holdings, according to a recent article in Bloomberg.

Berkshire purchased shares in Chevron Corp., Verizon Communications, and insurance brokerage firm Marsh & McLennan Cos., “three wagers that were granted confidential status and not revealed in a third-quarter regulatory filing,” the article reports.

The reduction in Apple holdings reportedly left Berkshire with a total of about $120 billion at the end of 2020, although the tech giant remains the firm’s largest single holding.

“Buffett and his investment deputies, Todd Combs and Ted Weschler, reshaped the portfolio over the last year as Covid-19 struck the U.S.,” the article says, adding, “The company was heavily invested in the banking sector, which has done well in the pandemic but is exposed to consumer finances and commercial real estate.”

The article reports that at the end of 2020, Berkshire’s investment in Chevron was valued at nearly $4.1 billion, its Marsh & McLennan bet was valued at $499 million and its Verizon holdings totaled $8.6 billion.
