Large-cap stocks have the power to shape entire industries thanks to their size and widespread influence. With such vast footprints, however, finding new areas for growth is much harder than for smaller, more agile players.
This dynamic can trouble even the most skilled investors, but luckily for you, we started StockStory to help you navigate these trade-offs and uncover exceptional companies that break the mold. That said, here is one large-cap stock that still has big upside potential and two whose momentum may slow.
Two Large-Cap Stocks to Sell:
AT&T (T)
Market Cap: $178.2 billion
Founded by Alexander Graham Bell, AT&T (NYSE: T) is a multinational telecomm conglomerate providing a range of communications and internet services.
Why Do We Pass on T?
- Flat sales over the last five years suggest it must innovate and find new ways to grow
- Performance over the past five years shows each sale was less profitable, as its earnings per share fell by 6.9% annually
- Free cash flow margin is expected to remain in place over the coming year
AT&T’s stock price of $25.98 implies a valuation ratio of 10.6x forward P/E. Dive into our free research report to see why there are better opportunities than T.
AIG (AIG)
Market Cap: $40.23 billion
With roots dating back to 1919 when it began as a small insurance agency in Shanghai, China, AIG (NYSE: AIG) is a global insurance organization that provides commercial and personal insurance solutions to businesses and individuals across more than 200 countries.
Why Is AIG Risky?
- Sales tumbled by 9.3% annually over the last five years, showing market trends are working against it during this cycle
- 4.7% annual declines in net premiums earned for the past five years indicates policy sales struggled this cycle
- Products and services are facing profitability challenges during this cycle, as seen in its flat book value per share over the last five years
At $76.94 per share, AIG trades at 1x forward P/B. To fully understand why you should be careful with AIG, check out our full research report (it’s free).
One Large-Cap Stock to Buy:
Trane Technologies (TT)
Market Cap: $98.78 billion
With low-pressure heating systems as its first product, Trane (NYSE: TT) designs, manufactures, and sells HVAC and refrigeration systems, the former to commercial and residential building customers and the latter to commercial truck manufacturers.
Why Will TT Outperform?
- Solid 10.4% annual revenue growth over the last five years indicates its offerings solve complex business issues
- Performance over the past five years was turbocharged by share buybacks, which enabled its earnings per share to grow faster than its revenue
- Free cash flow margin expanded by 10.8 percentage points over the last five years, providing additional flexibility for investments and share buybacks/dividends
Trane Technologies is trading at $451.44 per share, or 27.7x forward P/E. Is now a good time to buy? Find out in our full research report, it’s free.
