I ran a test of the biotech & drug companies and found that the percentage of insiders vs the percentage of institutional owner does seem to make a difference. I still have about 500 stock to do, but I am making headway. Here is the beginning. I also placed at the end column how much growth the stock made if you bought and held the stock for six years- when applicable. Remember, some companies are only a few years old. Check out, if you can read this chart, how much it made in relation to the amount of insiders/institutional ownership. Don't draw any conclusions, but it is beginning to look kind of one-sided.
Can you imagine owning a company like AEGN for six years in your portfolio, knowing that the company is owned by 58% institutions and after six long years your $3000 initial investment is now worth $53? Are all the institutions dumb? No. Since perception is in fact a reflection of what you believe to be true, my discernment must be that there are other things considered when an institution buys a stock, and making money for its loyal mutual followers isn't it.
