See Which Recent 13F Filers Hold GLW
At Holdings Channel, we have reviewed the latest batch of the 51 most recent 13F filings for the 06/30/2026 reporting period, and noticed that Corning Inc (Symbol: GLW) was held by 19 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 GLW positions, for this latest batch of 13F filers:
In terms of shares owned, we count 7 of the above funds having increased existing GLW positions from 03/31/2026 to 06/30/2026, with 7 having decreased their positions and 4 new positions.

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.
