CORNING INC (GLW)
Institutional ownership reported to the SEC as of Q2 2026, across 32 quarters.
Institutions report 640,824,789 shares against 861,388,331 outstanding. Shares only - option lines are excluded, which is why this can be compared with the company at all. The count comes from the cover page of the company's own most recent report, so it is dated when that was filed rather than at quarter end.
Calls and puts are the parts of reported value carried in derivative lines rather than shares, and they point in opposite directions: a manager holding calls is positioned for the security, one holding puts against it - or hedging shares they already own, which is why index funds carry so many. Most sites add the two together and report one figure, which averages away the only interesting part.

Q2 2026 in brief
In Q2 2026, 2,713 managers that file Form 13F reported holding Corning Inc (GLW), $173.1B in all, or about 73% of the shares outstanding. 581 managers opened a position and 147 sold out completely, against 2,279 holders the quarter before. Largest holders: Blackrock, Inc., Vanguard Capital Management Llc and State Street Corp. Largest new positions: Alkeon Capital Management Llc ($260.5M), Artisan Partners Limited Partnership ($182.7M) and Atalan Capital Partners, Lp ($152.6M).
Q2 2026 is the latest quarter whose 13F deadline has passed. A 13F shows long US stock positions at quarter end, filed up to 45 days later; an adviser and a sub-adviser can both report the same shares.
Tender offers and delisting
Schedules TO, 13E-3 and 14D-9 and Form 25 filed in the last 180 days. Price a share is read from the filing itself where it states one plainly; a marker means we found no figure we could stand behind, and the reason is on it.

What the insiders did
Open market purchases and sales reported on Form 4 in the last 180 days. Grants, option exercises and shares surrendered to cover tax are left out: they are compensation rather than a decision to buy or sell. Where a broker filled one order in tranches the lines are summed, because it was one decision.
