The 50 largest of the 68 funds that reported a position in MNR in their 13F for the quarter ended 30 June 2026, by the value each reported.

Share of all is the fund's part of all the shares the funds reported. Change is shares against the fund's 13F for the quarter before. A 13F lists a manager's long positions in US-listed shares at the quarter's end. What is a 13F?

Options the funds reported on MNR

Fund	Option	Shares under the options	Value of those shares	Quarter ended	Filing
Citadel Advisors	Calls	149,200	$1.9 million	30 June 2026	13F
Citadel Advisors	Puts	68,000	$859,520	30 June 2026	13F

A 13F lists calls and puts by the shares they cover and what those shares were worth at the quarter's end, not what the options cost.

They are not counted in the holdings above. A put gains when the stock falls, a call when it rises, and a fund may hold either to hedge.
