1 S&P 500 Stock Worth Investigating and 2 to Turn Down

BF.B Cover Image

The S&P 500 (^GSPC) is often seen as a benchmark for strong businesses, but that doesn’t mean every stock is worth owning. Some companies face significant challenges, whether it’s stagnating growth, heavy debt, or disruptive new competitors.

Picking the right S&P 500 stocks requires more than just buying big names, and that’s where StockStory comes in. Keeping that in mind, here is one S&P 500 stock that is leading the market forward and two best left off your watchlist.

Two Stocks to Sell:

Brown-Forman (BF.B)

Market Cap: $13.43 billion

Best known for its Jack Daniel’s whiskey, Brown-Forman (NYSE: BF.B) is an alcoholic beverage company with a broad portfolio of brands in wines and spirits.

Why Are We Wary of BF.B?

  1. Absence of organic revenue growth over the past two years suggests it may have to lean into acquisitions to drive its expansion
  2. Projected sales decline of 3% for the next 12 months points to an even tougher demand environment ahead
  3. Expenses have increased as a percentage of revenue over the last year as its operating margin fell by 6 percentage points

Brown-Forman’s stock price of $28.32 implies a valuation ratio of 14.6x forward P/E. If you’re considering BF.B for your portfolio, see our FREE research report to learn more.

Sherwin-Williams (SHW)

Market Cap: $87.91 billion

Widely known for its success in the paint industry, Sherwin-Williams (NYSE: SHW) is a manufacturer of paints, coatings, and related products.

Why Does SHW 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. Anticipated sales growth of 2.4% for the next year implies demand will be shaky
  3. Free cash flow margin shrank by 8.5 percentage points over the last five years, suggesting the company is consuming more capital to stay competitive

Sherwin-Williams is trading at $351.62 per share, or 28.6x forward P/E. To fully understand why you should be careful with SHW, check out our full research report (it’s free).

One Stock to Watch:

Republic Services (RSG)

Market Cap: $75.16 billion

Processing several million tons of recyclables annually, Republic (NYSE: RSG) provides waste management services for residences, companies, and municipalities.

Why Is RSG Interesting?

  1. Annual revenue growth of 9.3% over the last five years beat the sector average and underscores the unique value of its offerings
  2. Healthy operating margin of 18.6% shows it’s a well-run company with efficient processes, and its profits increased over the last five years as it scaled
  3. Strong free cash flow margin of 13.5% enables it to reinvest or return capital consistently

At $240.50 per share, Republic Services trades at 34.3x forward P/E. Is now the right time to buy? See for yourself in our full research report, it’s free.
