There are lots of big trades, exactly the same number of shares, that are trading within a cent or half a cent. It looks like some daytraders are just having fun, trading big lots of shares for a penny or less profit (both directions), which can be lucrative if you trade a lot of shares, and/or do it a few times per day.

Of course I could be wrong. Just saying this to avoid the usual "someone must know something" posts.
