There are plenty of investors who are wiser than me. Somebody bought a load of Generex stock yesterday. I presume that they did not do that with the intention of losing money. Considering where we were, .30 is a bargain basement price. There is no mystery here, to me anyway. I’ve been buying right along. My question is: who was selling all these shares and why? What’s the logic of selling that much, and at this point in time?
