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 is one volatile stock that could reward patient investors and two that might not be worth the risk.

Two Stocks to Sell:

Graham Corporation (GHM)

Rolling One-Year Beta: 1.43

Founded when its founder patented a unique design for a vacuum system used in the sugar refining process, Graham (NYSE: GHM) provides vacuum and heat transfer equipment for the energy, petrochemical, refining, and chemical sectors.

Why Are We Hesitant About GHM?

1. Responsiveness to unforeseen market trends is restricted due to its substandard operating margin profitability
2. Below-average returns on capital indicate management struggled to find compelling investment opportunities
3. Short cash runway increases the probability of a capital raise that dilutes existing shareholders

Graham Corporation’s stock price of $66.46 implies a valuation ratio of 46.1x forward P/E. Read our free research report to see why you should think twice about including GHM in your portfolio.

Delta (DAL)

Rolling One-Year Beta: 1.27

One of the ‘Big Four’ airlines in the US, Delta Air Lines (NYSE: DAL) is a major global air carrier that serves both business and leisure travelers through its domestic and international flights.

Why Do We Avoid DAL?

1. Performance surrounding its revenue passenger miles has lagged its peers
2. Forecasted free cash flow margin suggests the company will fail to improve its cash conversion over the next year
3. Improving returns on capital suggest management is identifying more profitable investments

Delta is trading at $71.75 per share, or 10.7x forward P/E. To fully understand why you should be careful with DAL, check out our full research report (it’s free for active Edge members).

One Stock to Watch:

SmartRent (SMRT)

Rolling One-Year Beta: 1.49

Founded by an employee at a real estate rental company, SmartRent (NYSE: SMRT) provides smart home devices and software for multifamily residential properties, single-family rental homes, and student housing communities.

Why Do We Watch SMRT?

1. ARR trends over the past two years show it’s maintaining a steady flow of long-term contracts that contribute positively to its revenue predictability
2. Earnings per share have massively outperformed its peers over the last three years, increasing by 24.1% annually
3. Returns on capital are increasing as management’s prior bets are starting to bear fruit

At $1.84 per share, SmartRent trades at 88x forward EV-to-EBITDA. Is now the right time to buy? See for yourself in our in-depth research report, it’s free for active Edge members.
