ChatGPT "Big Short" investor Michael Burry reveals bearish bets against the S&P 500 and Nasdaq-100 along with major changes to his stock portfolio.

Michael Burry placed bearish bets against the S&P 500 and Nasdaq-100 last quarter.

The "Big Short" investor also sold his stakes in Alibaba, First Republic, and many other stocks.

Burry's Scion fund loaded up on mining, shipping, and energy stocks during this period.

Last quarter, Michael Burry bet against the S&P 500 and Nasdaq-100 while shifting his investments from Chinese e-commerce giants and struggling banks to shipping, mining, and energy companies.

At the end of June, a Securities and Exchange Commission filing revealed that the "Big Short" investor held put options on SPDR S&P 500 and Invesco QQQ, two ETFs that track major index funds.

After buying discounted banking stocks in the first quarter, he sold off Capital One, First Republic, PacWest Bancorp, Wells Fargo, and Western Alliance.

Burry's Scion Asset Management also divested from Chinese internet giants Alibaba and JD.com, while adding Crescent Energy, Comstock Resources, Precision Drilling, Star Bulk Carriers, and Stellantis to its portfolio.

The only positions that remained unchanged were in Geo Group, Liberty Latin America, New York Community Bancorp, Signet Jewelers, Cigna Group, and The RealReal.

Despite the portfolio turnover, the total value of Scion's holdings remained steady at $111 million, excluding options.

Burry gained fame for his massive bet against the mid-2000s housing bubble, as chronicled in the book and movie "The Big Short." He is also known for investing in GameStop before it became a meme stock and for shorting Elon Musk's Tesla and Cathie Wood's Ark Innovation fund.

Additionally, the Scion chief is known for his grim warnings about asset bubbles and dire market crash predictions. In line with his reputation, he issued a one-word warning, "Sell," at the end of January. He later admitted in March that he was "wrong to say sell" and has since been quiet on social media.
