Great things are happening to the stocks in this article. They’re all outperforming the market over the last month because of positive catalysts such as a new product line, constructive news flow, or even a loyal Reddit fanbase.

While momentum can be a leading indicator, it has burned many investors as it doesn’t always correlate with long-term success. Keeping that in mind, here are three stocks that are likely overheated and some you should look into instead.

Carrier Global (CARR)

One-Month Return: +7.2%

Founded by the inventor of air conditioning, Carrier Global (NYSE: CARR) manufactures heating, ventilation, air conditioning, and refrigeration products.

Why Are We Out on CARR?

1. Organic revenue growth fell short of our benchmarks over the past two years and implies it may need to improve its products, pricing, or go-to-market strategy
2. Incremental sales over the last two years were much less profitable as its earnings per share fell by 2.8% annually while its revenue grew
3. Eroding returns on capital suggest its historical profit centers are aging

At $61.51 per share, Carrier Global trades at 22.8x forward P/E. If you’re considering CARR for your portfolio, see our FREE research report to learn more.

Trinity (TRN)

One-Month Return: +22.8%

Operating under the trade name TrinityRail, Trinity (NYSE: TRN) is a provider of railcar products and services in North America.

Why Are We Wary of TRN?

1. Demand cratered as it couldn’t win new orders over the past two years, leading to an average 27.8% decline in its backlog
2. Demand will likely be weak over the next 12 months as Wall Street expects flat revenue
3. 22.9 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

Trinity is trading at $34.51 per share, or 1.3x trailing 12-month price-to-sales. To fully understand why you should be careful with TRN, check out our full research report (it’s free).

United Natural Foods (UNFI)

One-Month Return: +4.9%

With a vast network of 55 distribution centers spanning approximately 30 million square feet of warehouse space, United Natural Foods (NYSE: UNFI) is North America's premier grocery wholesaler distributing natural, organic, and conventional products to over 30,000 retail locations across the US and Canada.

Why Do We Think UNFI Will Underperform?

1. The company has faced growth challenges as its 2.5% annual revenue increases over the last three years fell short of other consumer staples companies
2. Performance over the past three years shows its incremental sales were much less profitable, as its earnings per share fell by 37.9% annually
3. 6× net-debt-to-EBITDA ratio shows it’s overleveraged and increases the probability of shareholder dilution if things turn unexpectedly

United Natural Foods’s stock price of $38.00 implies a valuation ratio of 17.2x forward P/E. Check out our free in-depth research report to learn more about why UNFI doesn’t pass our bar.
