Pfizer isn’t new to the limelight. The company’s stock is included in dozens of health care, pharmaceutical and dividend , and Pfizer regularly makes headlines for its innovations in health care. But when its COVID-19 vaccine (developed alongside German biotech company BioNTech) was given emergency use authorization by the U.S. Food and Drug Administration in December 2020, the company gained renewed interest.

Pfizer’s stock price jumped on the development, and though it corrected in the following weeks, the stock continued to trade higher than it had been prior to the vaccine news.

It may be tempting to buy Pfizer stock based on recent headlines, but the reality is Pfizer’s potential success may be already baked into the stock price you’re paying today.

However, Pfizer offers a strong dividend that has increased since mid-2009, and in 2020, its stock price was less volatile than most of its competitors. (Remember, though, that past performance doesn't guarantee future results.)

Considering these factors, Pfizer may fit in better with a portfolio that needs a greater balance toward less-volatile, income-producing value stocks. This of course is just an example; there are dozens of factors that would go into balancing your particular portfolio and determining whether Pfizer may be an appropriate investment for you.
