Well, let's do the math. Let's say you get brought on after the stock popped. So after a stock pops, you have profit taking meaning that the stock will fall back some (watch what happens later on today 6/22/2012). Profit takers (including many new managers and employees) will sell and take profits from the "pop." Then reps get hired and stock price will be around upper 50s at the time (once the profit takers sell). Company gets bought at $80 a share (because we all know $100 a share is ridiculous and WAY overvalued---see additional commentary below).
So if I sign on at $58 a share with 2000 shares of stock options and ONXX gets bought out at $80, then I make (at best) $25 a share. $25 x 2000=$50,000
So now I have $50K. But I had to buy a $30K car to sign on with ONXX and I will likely be stuck with that car after the potential new buyer comes in and cleans house. So I end up with about $20K. Now, the market cap of the company jumped about $1.25 Billion just with today's stock activity. Carfilz won't likely do $500M in its best year. So, is this recent stock bump sustainable? Is the stock undervalued, overvalued, or just about right? These are all decisions YOU have to ask yourself.
I would love to see ONXX tell potential buyers to piss off and let the stock ride, split, ride, split, ride, split. And they may do it. The economy is about to take another downturn and many "big pharmas" are not in positions to be spending a lot of cash. So it may be a good gamble. But no big pharma is going to pay $100 a share. And the stock is likely already overvalued.
