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.
Some large-cap stocks are past their peak, and StockStory is here to help you separate the winners from the laggards. Keeping that in mind, here is one S&P 500 stock that is positioned to outperform and two that could be in trouble.
Two Stocks to Sell:
GoDaddy (GDDY)
Market Cap: $11.98 billion
Known for its memorable Super Bowl commercials that put it on the map, GoDaddy (NYSE:GDDY) is a domain registrar and web services provider that helps entrepreneurs establish an online presence through domain registration, website building, hosting, and e-commerce tools.
Why Do We Think GDDY Will Underperform?
- Customers had second thoughts about committing to its platform over the last year as its average billings growth of 3.6% underwhelmed
- Estimated sales growth of 5.9% for the next 12 months implies demand will slow from its two-year trend
- Operating margin expanded by 3 percentage points over the last year as it scaled and became more efficient
At $90.45 per share, GoDaddy trades at 2.3x forward price-to-sales. If you’re considering GDDY for your portfolio, see our FREE research report to learn more.
Deckers (DECK)
Market Cap: $14.81 billion
Established in 1973, Deckers (NYSE:DECK) is a footwear and apparel conglomerate with a portfolio of lifestyle and performance brands.
Why Should You Sell DECK?
- Constant currency growth was below our standards over the past two years, suggesting it might need to invest in product improvements to get back on track
- Responsiveness to unforeseen market trends is restricted due to its substandard operating margin profitability
- Capital intensity will likely ramp up in the next year as its free cash flow margin is expected to contract by 5.1 percentage points
Deckers is trading at $106.33 per share, or 13.7x forward P/E. Dive into our free research report to see why there are better opportunities than DECK.
