If IDCC is temporarily propping up the price with the buyback, it would make sense to step away for a little bit and let the price come to a lower level where they can pick up more shares for the same money. The risk is that they sign another major license before they finish the buy back. I trust the company and their agents have a plan of action for different price levels and are doing what they think is best to acquire shares as quickly and cheaply as possible.
