Yes, I was surprised also - pleasantly for now. Not an insider or shorter. At ask because they never seem to fill under the ask price when I go "all or nothing" mode. Plus, the spread was low ...In the US a 100k buy just occurred. A buy because it was at the ask/offer.
Very unusual as I check every trade.
A new buyer or a short cover. Either way......and this is a good thing... as I paraphrase Martha Stewart.
(And she knows a lot about insider trading). Joking of course on this slow day.
