A highly volatile stock can deliver big gains - or just as easily wipe out a portfolio if things go south. While some investors embrace risk, mistakes can be costly for those who aren’t prepared.

At StockStory, our job is to help you avoid costly mistakes and stay on the right side of the trade. Keeping that in mind, here is one volatile stock that could deliver huge gains and two best left to the gamblers.

Two Stocks to Sell:

Knight-Swift Transportation (KNX)

Rolling One-Year Beta: 1.27

Covering 1.6 billion loaded miles in 2023 alone, Knight-Swift Transportation (NYSE: KNX) offers less-than-truckload and full truckload delivery services.

Why Do We Think KNX Will Underperform?

1. 4.3% annual revenue growth over the last two years was slower than its industrials peers
2. 9.1 percentage point decline in its free cash flow margin over the last five years reflects the company’s increased investments to defend its market position
3. Diminishing returns on capital from an already low starting point show that neither management’s prior nor current bets are going as planned

Knight-Swift Transportation’s stock price of $45.55 implies a valuation ratio of 24.9x forward P/E. Dive into our free research report to see why there are better opportunities than KNX.

Shyft (SHYF)

Rolling One-Year Beta: 1.12

Notably receiving an order from FedEx for electric vehicles, Shyft (NASDAQ: SHYF) offers specialty vehicles and truck bodies for various industries.

Why Should You Dump SHYF?

1. Sales tumbled by 13.7% annually over the last two years, showing market trends are working against its favor during this cycle
2. Capital intensity has ramped up over the last five years as its free cash flow margin decreased by 6.8 percentage points
3. Waning returns on capital imply its previous profit engines are losing steam

At $12.54 per share, Shyft trades at 11.7x forward P/E. Check out our free in-depth research report to learn more about why SHYF doesn’t pass our bar.

One Stock to Buy:

Founded in 1999 and receiving its first FDA approval in 2006, DexCom (NASDAQ: DXCM) develops and sells continuous glucose monitoring systems that allow people with diabetes to track their blood sugar levels without repeated finger pricks.

Why Are We Bullish on DXCM?

1. Core business can prosper without any help from acquisitions as its organic revenue growth averaged 19.2% over the past two years
2. Incremental sales over the last five years have been highly profitable as its earnings per share increased by 23.2% annually, topping its revenue gains
3. Industry-leading 24.8% return on capital demonstrates management’s skill in finding high-return investments
