Third PRTA Check in a Month Pushes the Total Near $2M
A 10% owner just wrote another $889,872 into this Parkinson's drug developer, and that makes three buys in 30 days totaling almost $2 million. This buyer isn't guessing. He just grew his position by 124%, and healthcare is one of the few corners catching a defensive bid while rate-sensitive names get sold off. The tape is the sticking point. Short-term momentum turned up and price is reclaiming the 8-day, but the medium and long trends still read sell, and the stock sits square in the middle of its yearly range, which is the least revealing spot for an insider to buy. If the 8-day crosses over the 20-day from here, the algorithms join, and a trader who likes the owner's read could sell a put spread beneath his $8.60 buy price to get paid while waiting for that to play out.
