3 Stocks That Were Huge Winners Last Week

Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

The market's best-performing companies last week included three healthcare stocks that won over investors with can't-miss news. Two of these companies are highly speculative, emerging-stage biotech stocks that surged on optimism over drugs in their pipelines. The third is a specialty health insurer that is racking up profit thanks to the Affordable Care Act's Medicaid expansion.

It's anyone's guess whether these three companies will continue their winning ways in the months and years to come, but to help prepare you for any future pops-and-drops, I've prepared a slideshow below that highlights what you need to know about these company's recent moves.
