David Tepper posts 32% first-half return

According to Bloomberg's tally, the gain was driven mainly by his memory chip investments.

The result reaffirmed Tepper's standing in the investment industry. Memory chips played a central role in his portfolio and contributed substantially to the overall return.

Tepper's investment philosophy rests on a contrarian strategy: buy boldly when others are panicking, and sell when the market is cheering. It showed clearly in the 2009 financial crisis, when he concentrated on bank stocks and bonds and earned large returns.

He has achieved several successes through this willingness to go against market sentiment, and this half's return is seen as a product of the same philosophy.

David Tepper sold nearly 41% of his Micron shares, cutting his holding from 1.66 million to 975,000 shares. But after Micron's stock surged 242% last quarter, Micron's weight in his portfolio rose to 15%, making it his second-largest holding.

The stake adjustments suggest Tepper realized close to a 5x net gain on Micron. The move is read as strategic profit-taking combined with position management as the share price climbed.

David Tepper completed a full exit from SanDisk, which he had bought in the first quarter, during a 258% surge. According to CNBC's tally, he cleared a position worth more than $400 million.

He finished selling near the February peak and then avoided a decline of nearly 30% in the third quarter. The sale is widely regarded as a well-timed exit that captured a short-term spike.

David Tepper sold 42% of his Alibaba shares, cutting the position from 7.33% to 2.57% of the portfolio. He also fully liquidated his 900,000 shares of PDD, the parent of Temu, and his remaining JD.com stake, substantially reducing his exposure to Chinese e-commerce.

This appears to be a wholesale exit from Chinese e-commerce holdings, including related stocks such as the KWEB ETF. Baidu was the exception, with its weight increased.

Tepper's top new purchase this quarter was Boeing, with 800,000 shares worth $173 million. He also re-entered American Airlines with 7.5 million shares worth $136 million.

This looks like a sector strategy focused on airlines, similar to Druckenmiller's approach. The buys are read as bets on an airline industry recovery.

At the same time, he added 24% more to TSMC, a foundry, extending a six-quarter buying streak.

He also increased his Meta position by 55% when the stock fell, buying on the dip. This is read as a rotation within AI stocks aimed at improving portfolio efficiency.

Like Chrysalis, David Tepper fully liquidated his remaining Microsoft position, worth $33 million. A new position of 220,000 SpaceX shares, worth $38 million, also appeared.

There is speculation that the SpaceX position may have become subject to disclosure during its listing process.

A new position of 835,000 Apple put options, with a notional value of $242 million, also showed up.

Analysts differ on whether the Apple put purchase is a bet on a price decline or a portfolio hedge.

David Tepper cut his Whirlpool shares by 63%, cutting losses. The estimated return on this position was -50%. He also fully exited PDD, a Chinese e-commerce stock, for a return of -38%.

Overall, the portfolio strategy is summarized as taking profits in memory chips, re-buying airline stocks, and rotating positions within AI stocks.

When dealing with a stock that is surging, partial profit-taking is usually more effective than selling everything. If you have no clear edge or conviction about the timing of a buy or sell, splitting trades helps manage emotions and keeps room for new opportunities.

How you scale in and out should also fit your own style. Whether you prefer entering early or chasing later, a split-trading method suited to you can make your investing more efficient.
