At Holdings Channel, we have reviewed the latest batch of the 56 most recent 13F filings for the 03/31/2026 reporting period, and noticed that Micron Technology Inc. (Symbol: MU) was held by 31 of these funds. When hedge fund managers appear to be thinking alike, we find it is a good idea to take a closer look.
Before we proceed, it is important to point out that 13F filings do not tell the whole story, because these funds are only required to disclose their long positions with the SEC, but are not required to disclose their short positions. A fund making a bearish bet against a stock by shorting calls, for example, might also be long some amount of stock as they trade around their overall bearish position. This long component could show up in a 13F filing and everyone might assume the fund is bullish, but this tells only part of the story because the bearish/short side of the position is not seen.
Having given that caveat, we believe that looking at groups of 13F filings can be revealing, especially when comparing one holding period to another. Below, let's take a look at the change in MU positions, for this latest batch of 13F filers:
In terms of shares owned, we count 13 of the above funds having increased existing MU positions from 12/31/2025 to 03/31/2026, with 9 having decreased their positions and 7 new positions.
Looking beyond these particular funds in this one batch of most recent filers, we tallied up the MU share count in the aggregate among all of the funds which held MU at the 03/31/2026 reporting period (out of the 2,639 we looked at in total). We then compared that number to the sum total of MU shares those same funds held back at the 12/31/2025 period, to see how the aggregate share count held by hedge funds has moved for MU. We found that between these two periods, funds increased their holdings by 5,218,519 shares in the aggregate, from 26,007,333 up to 31,225,852 for a share count increase of approximately 20.07%. The overall top three funds holding MU on 03/31/2026 were:
| » | Fund | Shares of MU Held |
|---|---|---|
| 1. | SG Americas Securities LLC | 10,582,752 |
| 2. | ProShare Advisors LLC | 1,745,620 |
| 3. | Pictet Asset Management Holding SA | 1,230,731 |

We'll keep following the latest 13F filings by hedge fund managers and bring you interesting stories derived from a look at the aggregate information across groups of managers between filing periods. While looking at individual 13F filings can sometimes be misleading due to the long-only nature of the information, the sum total across groups of funds from one reporting period to another can be a lot more revealing and relevant, providing interesting stock ideas that merit further research, like Micron Technology Inc. (Symbol: MU).
