Not all profitable companies are built to last - some rely on outdated models or unsustainable advantages. Just because a business is in the green today doesn’t mean it will thrive tomorrow.

Profits are valuable, but they’re not everything. At StockStory, we help you identify the companies that have real staying power. Keeping that in mind, here are two profitable companies that generate reliable profits without sacrificing growth and one best left off your watchlist.

One Stock to Sell:

CSX (CSX)

Trailing 12-Month GAAP Operating Margin: 32%

Established as part of the Chessie System and Seaboard Coast Line Industries merger, CSX (NASDAQ: CSX) is a transportation company specializing in freight rail services.

Why Should You Sell CSX?

1. Weak unit sales over the past two years imply it may need to invest in improvements to get back on track
2. Sales were less profitable over the last two years as its earnings per share fell by 6.5% annually, worse than its revenue declines
3. Free cash flow margin dropped by 18.9 percentage points over the last five years, implying the company became more capital intensive as competition picked up

At $36.03 per share, CSX trades at 19.4x forward P/E. Dive into our free research report to see why there are better opportunities than CSX.

Two Stocks to Watch:

Nova (NVMI)

2. Earnings per share grew by 34.1% annually over the last five years, massively outpacing its peers
3. Robust free cash flow margin of 28.2% gives it many options for capital deployment
