Blackout period

Also called: trading blackout, closed window

In one line

A window during which insiders are barred from trading shares, typically around results or material news.

In plain English

Companies close trading 'windows' when insiders might hold material non-public information — for example before earnings. Trades are only allowed in the open windows between blackouts.

Times when nobody who knows club secrets is allowed to trade toys, to keep things fair for everyone.

Why it matters when you sell

A blackout can block you from selling exactly when you wanted to, so check the calendar before planning a trade.
