It is usually both. When the t-trade is printed a few seconds late at the current bid or ask price it's a trade that went through a little too late. T-trades of this size and nowhere near what the current bid and ask is a settlement from earlier in the day that they just settled.
That's another way MMs manipulate the market, by holding back trades and settling them after the bell.
A buy like that at .0132 would have spurred some mega buying imo.
