Do you consider yourself a contrarian investor? If so, we have just the list for you.

We began by screening the biotech industry for stocks with bearish sentiment from short sellers, with float shorts above 10%.

We then screened these names for those with the confidence of their company insiders, such as members of the board and upper management, with significant net insider purchases over the last six months representing at least 2% of share float. Since most companies only have a handful of company insiders, net insider purchases representing 2% of share float is a big show of confidence in their employer's prospects.
