Nvidia Corp. (NASDAQ: NVDA) remains the most widely held semiconductor stock among US active fund managers, present in 82% of portfolios as of end-August 2026, according to BofA Global Research.
However, traditional long-only managers hold Nvidia at just 1.17 times its S&P 500 weighting, indicating broad but modest conviction. Meanwhile, hedge funds are concentrating bets on other AI infrastructure names, notably Seagate Technology Holdings PLC (NASDAQ: STX) and SanDisk Corp. (NASDAQ: SNDK).
Most-Owned Chip Stocks Among US Funds
BofA semiconductor analyst Vivek Arya noted that Nvidia leads ownership, followed by Broadcom Inc. (NASDAQ: AVGO) at 78% and Advanced Micro Devices Inc. (NASDAQ: AMD) at 51%.
Intel Corp. (NASDAQ: INTC) stands out as an outlier. Despite having the fifth-largest market capitalization in the group, it ranks only 19th by ownership, held by just 21% of managers.

Memory Ownership Is Still Expanding
Ownership in memory stocks expanded significantly in August. SanDisk’s ownership jumped nearly nine percentage points to 24%, the largest monthly increase among tracked stocks. Micron Technology Inc. rose approximately six percentage points to 50%, securing the fourth-most-owned spot.
Where Hedge Funds Are Betting
Hedge funds show distinct preferences compared to long-only managers. They are more overweight in Seagate, Teradyne Inc., SanDisk, Synopsys Inc., Arista Networks Inc., CIEN, LRCX, and APH.
Seagate displays the sharpest divergence. Long-only managers held it below benchmark weight (0.86x), while hedge funds held it at 3.44 times the S&P 500 weight. SanDisk also saw heavy hedge fund interest, with positions at 2.57 times benchmark weight versus 1.04 times for long-only funds.
| Company | Hedge Fund Weight vs. S&P 500 | Long-Only Weight vs. S&P 500 |
|---|---|---|
| Seagate Technology Holdings PLC | 3.44x | 0.86x |
| Teradyne Inc. | 2.73x | 0.62x |
| SanDisk Corp. | 2.57x | 1.04x |
| Synopsys Inc. | 2.51x | 1.07x |
| Arista Networks Inc. | 2.57x | 1.22x |
What the Numbers Show
The data reveals a bifurcation in AI investment strategies. While Nvidia enjoys universal inclusion (82%), its modest overweight ratio (1.17x) suggests it is treated as a core, baseline holding by long-only funds. In contrast, hedge funds are taking aggressive, concentrated positions in peripheral infrastructure plays like Seagate (3.44x overweight) and SanDisk (2.57x overweight), indicating a search for alpha in specific sub-segments of the AI supply chain rather than broad exposure through the dominant chipmaker.
Could the significant divergence between hedge fund and long-only manager positions in Seagate and SanDisk signal an impending price correction or a sustained outperformance for these peripheral AI infrastructure plays?
How might Intel's low institutional ownership (21%) impact its ability to secure capital for its turnaround strategy compared to its higher-ranked peers like Nvidia and Broadcom?
If memory stock ownership continues to expand rapidly, will this lead to a supply-demand imbalance that could drive further margin expansion for Micron and SanDisk in the coming quarters?
