In this article, we will take a look at Billionaire Daniel Sundheim’s 10 Stocks Picks with Huge Upside Potential.

The upward momentum in the equity market is likely to continue heading into the year-end. It is a stance held by major investment banks in response to the economy and consumers showing resilience. Corporations delivering healthy pre-Liberation Day growth of more than 12% in the face of tariff rates have also benefited from double-digit corporate earnings growth.

Analysts at Goldman Sachs expect the S&P 500 to power through the 6,600 level before year-end as investors continue to shun valuation concerns. The analysts also expect 7% earnings-per-share growth for the S&P 500 this year and next.

“Recent inflation data and corporate surveys indicate less tariff pass-through so far than we expected,” the analysts said, reported Reuters. “However, we expect the digestion of tariffs to be a gradual process, and large-cap companies appear to have some buffer from inventories ahead of the increase in tariff rates.”

D1 Capital Partners, founded by billionaire Dan Sundheim, is one hedge fund that continues to capitalize on the market’s strong bullish momentum. The hedge fund was up by 11.8% for the year as of April, even as the overall market crumbled amid the weight of US tariffs.

The strong performance underscores how legendary investor Dan Sundheim has made a name for himself by generating significant returns regardless of the prevailing economic cycle. The former chief investment officer of Viking Global Investors is one of the most revered hedge fund managers on Wall Street. He launched D1 Capital Partners in 2018 with about $5 billion in capital after leaving Viking Global Investors, because he grew frustrated with the lack of a more flexible mandate.

“I think of Dan like LeBron James. Whatever team he is on is going to be a contender because he makes everyone else around him so much better,” one of Sundheim’s former Viking colleagues told Business Insider.

D1 Capital Partners has staged a strong recovery after tumbling 30.5% in 2022, stung by plunging tech stocks and declining venture valuations. Sundheim’s hedge fund is believed to have posted a 44% return on its portfolio in 2024, driven by strategic investments. The fund’s focus on European valuation discount was one of the catalysts behind the strong performance.

“We believe there is currently an extremely attractive opportunity to buy great businesses that trade on non-US exchanges,” Sundheim wrote in the letter.

As the equity market continues to edge higher amid the US Federal Reserve’s easing cycle, let’s look at some of billionaire Daniel Sundheim’s stock picks with huge upside potential.
