The stocks featured in this article are seeing some big returns. Over the past month, they’ve outpaced the market due to some combination of positive news, upbeat results, or supportive macro developments. As such, investors are taking notice and bidding up shares.

But not every company with momentum is a long-term winner, and plenty of investors have lost money betting on short-term fads. On that note, here are three stocks that are likely overheated and some you should look into instead.

Latham (SWIM)

One-Month Return: +14.5%

Started as a family business, Latham (NASDAQ: SWIM) is a global designer and manufacturer of in-ground residential swimming pools and related products.

Why Should You Sell SWIM?

1. Muted 6.2% annual revenue growth over the last five years shows its demand lagged behind its consumer discretionary peers
2. Operating margin of 4.6% falls short of the industry average, and the smaller profit dollars make it harder to react to unexpected market developments
3. Free cash flow margin is projected to show no improvement next year

Latham’s stock price of $6.34 implies a valuation ratio of 32.7x forward P/E. Check out our free in-depth research report to learn more about why SWIM doesn’t pass our bar.

CTS (CTS)

One-Month Return: +19.4%

With roots dating back to 1896 and a global manufacturing footprint, CTS (NYSE: CTS) designs and manufactures sensors, connectivity components, and actuators for aerospace, defense, industrial, medical, and transportation markets.

Why Does CTS Give Us Pause?

1. Sales stagnated over the last two years and signal the need for new growth strategies
2. Flat earnings per share over the last two years underperformed the sector average
3. Eroding returns on capital suggest its historical profit centers are aging

CTS is trading at $55.13 per share, or 22.9x forward P/E. Read our free research report to see why you should think twice about including CTS in your portfolio.

Aramark (ARMK)

One-Month Return: +15.9%

From serving hot dogs at major league stadiums to managing college dining halls that feed thousands daily, Aramark (NYSE: ARMK) provides food services and facilities management to schools, healthcare facilities, businesses, sports venues, and correctional institutions across 16 countries.

Why Are We Cautious About ARMK?

1. Products and services are facing end-market challenges during this cycle, as seen in its flat sales over the last two years
2. Earnings per share have dipped by 29.5% annually over the past two years, which is concerning because stock prices follow EPS over the long term
3. Lacking free cash flow generation means it has few chances to reinvest for growth, repurchase shares, or distribute capital

At $45.06 per share, Aramark trades at 19.1x forward P/E. To fully understand why you should be careful with ARMK, check out our full research report (it’s free).
