Corinne Cardina: What are three things you think investors should consider before buying a coronavirus vaccine stock?

Adria Cimino: Well, one of the things I think is growth potential and this gets back to your comfort level of if you want to buy a smaller growth stock or a bigger stock. The idea is something like, for instance, Vaxart (VXRT 14.63%) is an $814 million company, whereas Johnson & Johnson (JNJ 0.52%) is a $400 billion company. You're going to have more potential for growth with Vaxart, but you also have higher risk because it's an unproven program. Consider that and see what you are more comfortable with. I would say also long-term opportunities versus the immediate pandemic -- or long-term opportunity and the immediate pandemic that we have right now. The idea is certain stocks might do really well right away on this via selling the vaccine. But how is that going to pan out into the future? I would like the company that has a lot of things in the pipeline so that eventually, if there is less demand for the vaccine, other things will pick up following that. Then finally, I would say other benefits can be various things like the fundamental business, dividends that might be paid. Like with a pharmaceutical company, you'll get dividends. With a small biotech, you won't. Also, the pipeline size. So, the size of the pipeline, the stages, and the product portfolio. A company that has a huge product portfolio with revenue that's been rising through the past few years, there's value in that too.
