Expensive stocks typically earn their valuations through superior growth rates that other companies simply can’t match. The flip side though is that these lofty expectations make them particularly susceptible to drawdowns when market sentiment shifts.
Finding the right balance between price and quality can challenge even the most skilled investors. Luckily for you, we started StockStory to help you identify the real opportunities. That said, here is one high-flying stock with strong fundamentals and two facing an uphill battle.
Two High-Flying Stocks to Sell:
Fluence Energy (FLNC)
Forward P/E Ratio: 141.8x
Pioneering the use of lithium-ion batteries for grid storage, Fluence (NASDAQ:FLNC) helps store renewable energy sources with battery systems.
Why Does FLNC Give Us Pause?
- Historically negative EPS casts doubt for cautious investors and clouds its long-term earnings prospects
- Cash burn makes us question whether it can achieve sustainable long-term growth
- Negative earnings profile makes it challenging to secure favorable financing terms from lenders
Fluence Energy is trading at $10.91 per share, or 141.8x forward P/E. Check out our free in-depth research report to learn more about why FLNC doesn’t pass our bar.
Artivion (AORT)
Forward P/E Ratio: 52x
Formerly known as CryoLife until its 2022 rebranding, Artivion (NYSE:AORT) develops and manufactures medical devices and preserves human tissues used in cardiac and vascular surgical procedures for patients with aortic disease.
Why Are We Cautious About AORT?
- Revenue base of $471.5 million puts it at a disadvantage compared to larger competitors exhibiting economies of scale
- Cash-burning history makes us doubt the long-term viability of its business model
- ROIC of 2.4% reflects management’s challenges in identifying attractive investment opportunities
At $26.92 per share, Artivion trades at 52x forward P/E. Dive into our free research report to see why there are better opportunities than AORT.
One High-Flying Stock to Buy:
Corning (GLW)
Forward P/E Ratio: 40.5x
Supplying windows for some of the United States’s earliest spacecraft, Corning (NYSE:GLW) provides glass and other electronic components for the consumer electronics, telecommunications, automotive, and healthcare industries.
Why Is GLW a Top Pick?
- Market share has increased this cycle as its 14.3% annual revenue growth over the last two years was exceptional
- Earnings per share have massively outperformed its peers over the last two years, increasing by 30.3% annually
- Free cash flow margin jumped by 5.9 percentage points over the last five years, giving the company more resources to pursue growth initiatives, repurchase shares, or pay dividends
Corning’s stock price of $144.24 implies a valuation ratio of 40.5x forward P/E. Is now the right time to buy? See for yourself in our full research report, it’s free.
