Peregrine (NAS: PPHM) saw shares jump up a very healthy 81% in November, but the stock is still down 75% from its 52-week high back in September, so it still has a long way to go to make up that ground.

However, this isn't to say that the drug doesn't work; Peregrine still has Bavituximab in trials for multiple types of cancer. This rebound in the stock may be showing that investors are now comfortable coming back to Peregrine at its lower valuation, for the promise it may still have.
