Just my opinion, but I'd say it is shaking out the margin calls. Under $2 and it can not be margin bought. At least that is how it works on Etrade. Even if you don't use margin on KRY it will impact your overall margin credit line. On Monday some will have gotten margin call notices and have until today or tomorrow to liquidate or add funds.

Most people lean toward selling their weak hands and from a price performance point of view KRY has been weak.

If the MM was looking for a great way to shake more shares, using margin calls is a good one.

Just my opinion.
