nice move...it appears someone knows what's coming and is will to pay a premium to have some shares before the announcement. regardless, it is nice to have some volume and price action. With so little shares available, people who "know" have no choice but to pay the premium.
i wonder what is coming? we know FDA re-submittal is still at least 4-6 weeks away, then FDA will resume the review. perhaps, its more equipment placements, or even better....a partnership.
