Nuveen Municipal High Income O (NMZ) Insider Activity
What the officers, directors and large holders did with their own shares.
Only open-market purchases and sales count toward the totals — grants,
option exercises and shares withheld for tax are compensation mechanics, not
decisions, and they're listed separately below.
Insider signalSubduedSelling ran below NMZ's own trailing one-year pace, with 0% of sale value under a prearranged plan.

Form 4s are due within two business days of a transaction, so this is close to
real time — unlike the quarterly 13F data on the Institutional tab. A single
large sale often reflects a prearranged 10b5-1 plan rather than a fresh view,
so read a pattern of sales rather than any one of them.
