Short term treasury ETF “BIL” down as much as 5% tonight on Schwab

The treasury ETF based on the 1 to 3mo treasury yields, BIL, is down as much as 5% versus Friday’s close on Schwab’s 24hr platform as of 8pm CDT.

That product should never have a down day due to its nature, except when it goes ex-dividend, which it didn’t over the weekend. Crazy that margin calls are dropping BIL like that. Almost a guaranteed 3% return in a day to buy it right now. Wild.
