3 Value Stocks That Concern Us

TDC Cover Image

Value investing has created more billionaires than any other strategy, like Warren Buffett, who built his fortune by purchasing wonderful businesses at reasonable prices. But these hidden gems are few and far between - many stocks that appear cheap often stay that way because they face structural issues.

This distinction between true value and value traps can challenge even the most skilled investors. Luckily for you, we started StockStory to help you uncover exceptional companies. That said, here are three value stocks with poor fundamentals and some alternatives you should consider instead.

Teradata (TDC)

Forward P/S Ratio: 1.2x

Pioneering data warehousing technology in the 1980s before "big data" was a common term, Teradata (NYSE: TDC) provides cloud-based data analytics and AI platforms that help large enterprises integrate, analyze, and leverage their data across multiple environments.

Why Should You Sell TDC?

  1. Products, pricing, or go-to-market strategy need some adjustments as its billings have averaged 6.2% declines over the last year
  2. Sales are projected to tank by 2.5% over the next 12 months as its demand continues evaporating
  3. Gross margin of 59.3% is way below its competitors, leaving less money to invest in areas like marketing and R&D

Teradata’s stock price of $21.26 implies a valuation ratio of 1.2x forward price-to-sales. Dive into our free research report to see why there are better opportunities than TDC.

Owens Corning (OC)

Forward P/E Ratio: 11.2x

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

Why Does OC Give Us Pause?

  1. Core business is underperforming as its organic revenue has disappointed over the past two years, suggesting it might need acquisitions to stimulate growth
  2. Free cash flow margin dropped by 7.6 percentage points over the last five years, implying the company became more capital intensive as competition picked up
  3. Shrinking returns on capital suggest that increasing competition is eating into the company’s profitability

Owens Corning is trading at $155.18 per share, or 11.2x forward P/E. If you’re considering OC for your portfolio, see our FREE research report to learn more.

BNY Mellon (BK)

Forward P/E Ratio: 14.3x

Tracing its roots back to 1784 when it was founded by Alexander Hamilton, BNY Mellon (NYSE: BK) is a global financial institution that provides asset servicing, wealth management, and investment services to institutions, corporations, and high-net-worth individuals.

Why Does BK Fall Short?

  1. Large revenue base makes it harder to increase sales quickly, and its annual revenue growth of 3.8% over the last five years was below our standards for the financials sector
  2. Annual tangible book value per share growth of 3.6% over the last five years lagged behind its financials peers as its large balance sheet made it difficult to generate incremental capital growth
  3. Below-average return on equity indicates management struggled to find compelling investment opportunities

At $104.11 per share, BNY Mellon trades at 14.3x forward P/E. Read our free research report to see why you should think twice about including BK in your portfolio.
