Why would serious investors sell at $10.35 when they could've sold at $11.50 or $11.90?

Why would serious investors sell at $10.35 when they could've sold at $11.50 or $11.90? And why would they be selling when XBI is rising? Seems "someone" is trying to hold the price down.
Why would serious investors buy at $10.335 when they could have bought at $7.5 a month ago? Seems someone is trying to hold the price up — stock manipulation? Long-buying (as opposed to short-selling) going on?
