Short-interest history
FINRA reports open short positions for a settlement date. The publication date is later. These are reported positions, with a separate date for each observation.
Compare the reported short exposure around the dates you bought, sold or watched MUB. A long position benefits from price rises; a short position benefits from falls. A change in these counts does not predict either move.

Change = this settlement’s shares short − the previous recorded settlement’s shares short; percentage change divides by that earlier count. A zero earlier count has no percentage change. Split-spanning counts are left uncompared. Float percentages use the stored settlement observation, not today’s float.

Cash dividend · Polygon event record
Up to six Polygon cash-dividend events, including recorded ex-dates within the next 120 days. Amounts retain their recorded currency and decimal precision. Historical amounts are not restated to a common split basis, annualized, or converted to dollars.
For a long holding, compare the ex-date with when you held the shares and check the pay date against your broker’s cash history. Owning the stock today does not establish past entitlement. For a short holding, a dividend can create a payment obligation to the share lender.

Split history
No qualified split events are stored. This does not establish that the stock has never split.
Up to six stored split dates through Nov 7, 2026. Equivalent vendor ratios are combined; conflicting ratios are left out. This history may be incomplete.
A split changes the share count and per-share price basis; it does not by itself add investment value. Put your holding’s earlier and later share counts on the same basis before comparing them. This applies to both long shares and shares owed on a short position.
