The stocks featured in this article have all approached their 52-week highs. When these price levels hit, it typically signals strong business execution, positive market sentiment, or significant industry tailwinds.

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

Restaurant Brands (QSR)

One-Month Return: +2.5%

Formed through a strategic merger, Restaurant Brands International (NYSE: QSR) is a multinational corporation that owns three iconic fast-food chains: Burger King, Tim Hortons, and Popeyes.

Why Do We Think Twice About QSR?

1. Estimated sales growth of 4.3% for the next 12 months implies demand will slow from its six-year trend
2. Day-to-day expenses have swelled relative to revenue over the last year as its operating margin fell by 5.4 percentage points
3. Incremental sales over the last six years were less profitable as its 5.1% annual earnings per share growth lagged its revenue gains

Restaurant Brands is trading at $72.10 per share, or 17.8x forward P/E. Check out our free in-depth research report to learn more about why QSR doesn’t pass our bar.

Assurant (AIZ)

One-Month Return: -4.4%

With roots dating back to 1892 when it was founded by a Civil War veteran, Assurant (NYSE: AIZ) provides specialized insurance products and services that protect major consumer purchases like mobile devices, vehicles, homes, and appliances.

Why Are We Wary of AIZ?

1. Net premiums earned only expanded by 4.8% annually over the last five years, trailing its insurance peers as its scale limited incremental business
2. Earnings growth underperformed the sector average over the last two years as its EPS grew by just 13.1% annually
3. Large asset base makes it harder to grow book value per share quickly, and its annual book value per share growth of 2.8% over the last five years was below our standards for the insurance sector

At $231.89 per share, Assurant trades at 1.8x forward P/B. Dive into our free research report to see why there are better opportunities than AIZ.

Atmus Filtration Technologies (ATMU)

One-Month Return: +5.2%

Spun out of Cummins in 2023 after 65 years as part of the engine maker, Atmus Filtration Technologies (NYSE: ATMU) manufactures filters for trucks, construction equipment, and agriculture machinery to reduce emissions and protect engines.

Why Is ATMU Not Exciting?

1. Sales trends were unexciting over the last two years as its 4.1% annual growth was below the typical industrials company
2. High input costs result in an inferior gross margin of 26.3% that must be offset through higher volumes
3. 3.4 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

Atmus Filtration Technologies’s stock price of $63.74 implies a valuation ratio of 21.3x forward P/E. If you’re considering ATMU for your portfolio, see our FREE research report to learn more.
