Volatility cuts both ways - while it creates opportunities, it also increases risk, making sharp declines just as likely as big gains. This unpredictability can shake out even the most experienced investors.

These stocks can be a rollercoaster, and StockStory is here to guide you through the ups and downs. That said, here are two volatile stocks that could deliver huge gains and one that might not be worth the risk.

One Stock to Sell:

Coursera (COUR)

Rolling One-Year Beta: 1.41

Founded by two Stanford University computer science professors, Coursera (NYSE:COUR) is an online learning platform that offers courses, specializations, and degrees from top universities and organizations around the world.

Why Does COUR Give Us Pause?

  1. Decision to emphasize platform growth over monetization has contributed to 7.3% annual declines in its average revenue per customer
  2. Estimated sales growth of 6% for the next 12 months implies demand will slow from its three-year trend
  3. Highly competitive market means it’s on the never-ending treadmill of sales and marketing spend

At $7.30 per share, Coursera trades at 6.1x forward EV/EBITDA. Read our free research report to see why you should think twice about including COUR in your portfolio.

Two Stocks to Watch:

Impinj (PI)

Rolling One-Year Beta: 1.91

Founded by Caltech professor Carver Mead and one of his students Chris Diorio, Impinj (NASDAQ:PI) is a maker of radio-frequency identification (RFID) hardware and software.

Why Should PI Be on Your Watchlist?

  1. Annual revenue growth of 20.2% over the last five years was superb and indicates its market share increased during this cycle
  2. Incremental sales over the last five years have been highly profitable as its earnings per share increased by 49.4% annually, topping its revenue gains
  3. Free cash flow margin increased by 15.8 percentage points over the last five years, giving the company more capital to invest or return to shareholders
