In this article, we will discuss Renaissance Technologies Returns, AUM, CEO, and the 10 Top Semiconductor Stock Picks.

Semiconductor stocks are in the midst of a historic rally, powered by the artificial intelligence-driven supercycle and a strong cyclical recovery in smartphones and PCs. Hyperscalers pouring billions of dollars into data center GPUs and AI accelerators are also driving record-shattering revenues for chip designers and manufacturers.

The S&P Global Semiconductor Index is already up 93% year to date, following a 203.58% return over the past year, resulting in massive valuation surges across the industry. The Philadelphia SE Semiconductor index has soared 64%, compared to a nearly 17% gain for the S&P 500 since March.

The significant gains underline investors’ charge into chip stocks, shrugging off concerns of a bubble burst.

“Just the thought of suggesting we are in a semiconductor supercycle and not a bubble reminds us of the five most dangerous words in investing: ‘it is different this time,” said Ned Davis Research strategist Pat Tschosik.

The semiconductor supercycle is no longer driven by PCs and smartphones, but by artificial intelligence models that are driving exponential demand growth. According to research firm Gartner, worldwide semiconductor revenue is projected to rise 64% to $1.3 trillion this year, as semiconductor and semiconductor equipment companies are expected to increase earnings by 95%.

“It’s really the AI infrastructure buildout. It’s the computing needs, it’s the networking needs,” said King Lip, chief strategist at BakerAvenue Wealth Management in San Francisco, which has overweighted semi stocks ‌in its portfolios. “It’s really a multi-year capex cycle — very exciting in our view as it relates to semiconductors.”

Renaissance Technologies is one hedge fund that has positioned itself to capitalize on the semiconductor supercycle. The hedge fund was founded in 1982 by mathematician Jim Simons, who passed away on May 10, 2024, at age 86 with a net worth estimated at $31.4 billion. The firm has been led by CEO Peter Fitzhugh Brown since 2017, when he became sole CEO after co-CEO Robert Mercer stepped down. Brown also took over as Chairman of the Board in January 2021.

Renaissance Technologies’ assets under management peaked at around $130 billion in 2021, and today its core 13F equity portfolio is valued at $63.9 billion as of regulatory filings from earlier this year, representing its disclosed US-listed long equity positions. The firm continues to operate the legendary Medallion Fund, which has been restricted to Renaissance employees since 1993 and is widely considered the most successful hedge fund in history, reportedly delivering annualized returns of roughly 39% net of fees (66% gross) over more than three decades.

That track record earned Simons the title of “the most successful hedge fund manager of all time.” Its externally available funds: the Renaissance Institutional Equities Fund (RIEF), Renaissance Institutional Diversified Alpha (RIDA), and Renaissance Institutional Diversified Global Equities (RIDGE), have had more uneven performance.

Renaissance Technologies generated a 9.64% return in its flagship Renaissance Institutional Equities Fund (RIEF) in 2025, as the firm’s legendary, employee-only Medallion Fund is believed to have generated  close to 20% return.

Our Methodology

For this list, we began by scanning Renaissance Technologies’ 13F portfolio as of the end of Q1 2026 and identified the hedge fund’s semiconductor stock holdings. We ended up with dozens of stocks in our initial pool and applied additional filters to select the top semiconductor stock picks. We looked for semiconductor companies that have recently had noteworthy news events. After that, we selected stocks in which Renaissance Technologies has more than $2 million in equity stake and that are popular with other hedge funds in Q1 2026. Finally, we ranked the stocks in ascending order based on Renaissance Technologies’ equity value in them.

Why are we interested in the stocks that hedge funds pile into? The reason is simple: our research shows we can outperform the market by imitating the top stock picks of the best hedge funds. Our quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 498.7% since May 2014, beating its benchmark by 303 percentage points (see more details here).
