Two new 13D holders filed in December on ACRX----with Perceptive Advisors with a 14.25% stake and ACP IV with a 7.5% position. Onward & upwards...............!
If news comes after the first, we'll definitely know there was a leak! Crazy % increase and volume picking up nicely!
One would expect more volume when you add an offering of 14,000,000 shares.
