Just find (or find the lack of) unperceived value.
Most pharmacists are actually pretty good at telling if a drug is BS, sales are getting eroded by new competition, likely to get taken off the market, or the marketplace is overhyping things. I'd even wager that analysts don't sufficiently include patent expiry very well (Who in this world would buy Pfizer??? What will they sell with no more Lipitor and Viagra?)
Personal story:
When the whole H1N1 thing was coming out, I was doing a practical placement at a hospital, and receiving the public health emails about suspicious cases involving young otherwise healthy people returning to Mexico. In other words, I had info that was public, but realistically, financial people didn't pay any attention to, and mind as well have been "inside" info. And the whole thing just kept growing and growing.
So I looked up the neuraminidase inhibitors that are available, zanamavir, oseltamavir, and a novel injectable undergoing Phase II (or was it III?) trials, peramivir.
This was in mid-late March 2009 I believe, and the stock was around $1.50.
Since I was toward the very end of my schooling, I was penny-less. Most of us are never poorer at any part of their careers than they are at this point.
I guess I could've made a good chunk of change, no?

Secondly, pharmacists typically have more stable incomes than others, so they should be playing the "buy low, sell high" game better than most. I think I'm going to load on some JNJ soon, I think I can "stomach" a P/E of 12
