3 Inflated Stocks with Questionable Fundamentals

Exciting developments are taking place for the stocks in this article. They’ve all surged ahead of the broader market over the last month as catalysts such as new products and positive media coverage have propelled their returns.

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 overhyped stocks that may correct and some you should consider instead.

Penguin Solutions (PENG)

One-Month Return: -16.6%

Based in the US, Penguin Solutions (NASDAQ:PENG) is a diversified semiconductor company offering memory, digital, and LED products.

Why Do We Pass on PENG?

1. 4% annual revenue growth over the last five years was slower than its semiconductor peers
2. Competitive supply chain dynamics and steep production costs are reflected in its low gross margin of 29.1%
3. ROIC of 4.8% reflects management’s challenges in identifying attractive investment opportunities, and its shrinking returns suggest its past profit sources are losing steam

At $21.39 per share, Penguin Solutions trades at 10.6x forward P/E. Check out our free in-depth research report to learn more about why PENG doesn’t pass our bar.

Warner Bros. Discovery (WBD)

One-Month Return: +41.1%

Formed from the merger of WarnerMedia and Discovery, Warner Bros. Discovery (NASDAQ:WBD) is a multinational media and entertainment company, offering television networks, streaming services, and film and television production.

Why Should You Sell WBD?

1. Sales tumbled by 4.2% annually over the last two years, showing consumer trends are working against its favor
2. Performance over the past five years shows its incremental sales were much less profitable, as its earnings per share fell by 30.9% annually
3. Eroding returns on capital from an already low base indicate that management’s recent investments are destroying value

Warner Bros. Discovery’s stock price of $17.70 implies a valuation ratio of 5x forward EV-to-EBITDA. If you’re considering WBD for your portfolio, see our FREE research report to learn more.

MasTec (MTZ)

One-Month Return: +7.4%

Involved in the 1996 Olympic Games MasTec (NYSE:MTZ) is an infrastructure construction company that specializes in the telecommunications, energy, and utility industries.

Why Does MTZ Fall Short?

1. Gross margin of 13.1% reflects its high production costs
2. Growth came at the expense of profits over the last five years as its substandard operating margin deteriorated even further
3. 3.8 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

MasTec is trading at $204.25 per share, or 29.8x forward P/E. Dive into our free research report to see why there are better opportunities than MTZ.
