Warren Buffett's Berkshire Hathaway made striking changes to its stock portfolio last quarter.
The famed investor's company cut its stake in Taiwan Semiconductor — which it only established in the third quarter of last year — by 86% to 8.3 million shares.
Buffett's conglomerate also pared its US Bancorp stake by 91% to fewer than 7 million shares, worth just under $300 million at the end of December.
Similarly, it sliced its BNY Mellon position by about 60% to 25 million shares, worth $1.1 billion at year end.
Berkshire didn't add any new names to its US stock portfolio last quarter, nor did it eliminate any holdings.
