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 getting more buzz than they deserve and some you should buy instead.

Griffon (GFF)

One-Month Return: +27.6%

Initially in the defense industry, Griffon (NYSE: GFF) is a now diversified company specializing in home improvement, professional equipment, and building products.

Why Do We Think Twice About GFF?

1. Products and services are facing significant end-market challenges during this cycle as sales have declined by 2.7% annually over the last two years
2. Sales are projected to tank by 28.7% over the next 12 months as its demand continues evaporating

Griffon’s stock price of $90.81 implies a valuation ratio of 16.8x forward P/E. To fully understand why you should be careful with GFF, check out our full research report (it’s free).

Advanced Energy (AEIS)

One-Month Return: +15.3%

Pioneering technologies for radio frequency power delivery, Advanced Energy (NASDAQ: AEIS) provides power supplies, thermal management systems, and measurement and control instruments for various manufacturing processes.

Why Are We Hesitant About AEIS?

1. 4.2% annual revenue growth over the last two years was slower than its industrials peers
2. Earnings growth over the last five years fell short of the peer group average as its EPS only increased by 4.1% annually
3. Diminishing returns on capital suggest its earlier profit pools are drying up

At $380.18 per share, Advanced Energy trades at 43.1x forward P/E. Read our free research report to see why you should think twice about including AEIS in your portfolio.

Benchmark (BHE)

One-Month Return: +15.3%

Operating as a critical behind-the-scenes partner for complex technology products since 1979, Benchmark Electronics (NYSE: BHE) provides advanced manufacturing, engineering, and technology solutions for original equipment manufacturers across aerospace, medical, industrial, and technology sectors.

Why Does BHE Give Us Pause?

1. Annual sales declines of 3.2% for the past two years show its products and services struggled to connect with the market during this cycle
2. Poor free cash flow margin of 0.7% for the last five years limits its freedom to invest in growth initiatives, execute share buybacks, or pay dividends
3. Low returns on capital reflect management’s struggle to allocate funds effectively

Benchmark is trading at $65.75 per share, or 25.6x forward P/E. Dive into our free research report to see why there are better opportunities than BHE.
