Somebody (not pj) has been showing size on the buy side in the $4.40's recently. They're cagey, though, and pull back at the first whiff of size on the sell side. I bid to "keep 'em honest" with the price.
My self-righteous posturing has inspired me to request that any posters addressing me use, "SirPJ" or "YourHonor" in doing so.
and, of course, to shrug and take any shares that fall into my lap at my bid price.
