Let’s see what the big blue whale bought and sold in the first quarter of 2023. Major moves and high conviction plays only.

Berkshire Hathaway (Warren Buffett) picks up 2.6% of Capital One (NYSE:COF) — the US’ third-largest issuer of Visa and Mastercard.

• Sold Berkshire’s entire stake in the world’s largest chip manufacturer Taiwan Semiconductors (NYSE:TSM), over Taiwan’s geopolitical tensions.
• Sold several bank positions, including US Bancorp (NYSE:USB) and Bank of New York Mellon (NYSE:BK) — after expressing concerns over the sector.

Here’s what “superinvestors” bought (see full list):

Onto the smaller orca whales (faves from TAJ). But don’t discount their size; they’re more nimble and are known to be top-performers killers.

• Skye Global Management starts a new call position (4.7% of portfolio) on Amazon (NASDAQ:AMZN) — who’s been left in the shadows of other big tech giants this year.
• North Peak Capital bought Avantor (NYSE:AVTR) — which provides chemicals and lab equipment to life sciences companies (12% of portfolio).
• Legion Partners scooped up cloud communications provider Twilio (NYSE:TWLO) and now makes up 11.8% of its portfolio. Over the past two years, the stock has been crushed, down 90%.

One more bonus whale was spotted — and this one flops around often…

Michael Burry goes big on Chinese e-commerce giants — adding to his JD (NASDAQ:JD) and Alibaba (NYSE:BABA), which now makes up nearly 20% of his portfolio.

• The investor, made famous from The Big Short, tweeted “sell” in January, just to say he “was wrong to say sell.”
• Instead, he loaded up on bank stocks, including the now-collapsed First Republic.
