Wall Street is overwhelmingly bullish on the stocks in this article, with price targets suggesting significant upside potential. However, it’s worth remembering that analysts rarely issue sell ratings, partly because their firms often seek other business from the same companies they cover.

Luckily for you, we at StockStory have no conflicts of interest - our sole job is to help you find genuinely promising companies. That said, here are three stocks where Wall Street may be overlooking some important risks and some alternatives with better fundamentals.

Lattice Semiconductor (LSCC)

Consensus Price Target: $161.71 (52% implied return)

A global leader in its category, Lattice Semiconductor (NASDAQ: LSCC) is a semiconductor designer specializing in customer-programmable chips that enhance CPU performance for intensive tasks such as machine learning.

Why Are We Cautious About LSCC?

1. Annual revenue growth of 1.9% over the last two years was below our standards for the semiconductor sector
2. Costs have risen faster than its revenue over the last five years, causing its operating margin to decline by 16.8 percentage points
3. Free cash flow margin was stuck in limbo over the last five years

Lattice Semiconductor’s stock price of $106.40 implies a valuation ratio of 40.1x forward P/E. Read our free research report to see why you should think twice about including LSCC in your portfolio.

Owens Corning (OC)

Consensus Price Target: $146.94 (31% implied return)

Credited with the discovery of fiberglass, Owens Corning (NYSE: OC) supplies building and construction materials to the United States and international markets.

Why Should You Sell OC?

1. 2.9% annual revenue growth over the last two years was slower than its industrials peers
2. Performance over the past two years shows its incremental sales were much less profitable, as its earnings per share fell by 20.2% annually
3. Diminishing returns on capital suggest its earlier profit pools are drying up

Owens Corning is trading at $112.19 per share, or 11.2x forward P/E. Check out our free in-depth research report to learn more about why OC doesn’t pass our bar.

RadNet (RDNT)

Consensus Price Target: $94.63 (38.5% implied return)

With over 350 imaging facilities across seven states and a growing artificial intelligence division, RadNet (NASDAQ: RDNT) operates a network of outpatient diagnostic imaging centers across the United States, offering services like MRI, CT scans, PET scans, mammography, and X-rays.

Why Does RDNT Give Us Pause?

1. Incremental sales over the last five years were much less profitable as its earnings per share fell by 7.8% annually while its revenue grew
2. Ability to fund investments or reward shareholders with increased buybacks or dividends is restricted by its weak free cash flow margin of 1.9% for the last five years
3. Low returns on capital reflect management’s struggle to allocate funds effectively, and its shrinking returns suggest its past profit sources are losing steam

At $68.30 per share, RadNet trades at 120.2x forward P/E. To fully understand why you should be careful with RDNT, check out our full research report (it’s free).
