What Is a PE Ratio?
For those newer to investing, the PE ratio (Price-to-Earnings ratio) is one of the most commonly used valuation tools. It measures how much investors are willing to pay for $1 of a company’s earnings.
A high PE ratio typically indicates that investors expect high future growth. For example, a stock with a PE of 60 means you’re paying $60 for every $1 the company earns—often because you expect it to earn much more in the future. Learn more about how the PE ratio works from Investopedia.

Why High-PE Growth Stocks Are So Popular
High-PE stocks are often technology or disruptive companies that show incredible revenue growth, even if they’re not yet profitable. These stocks attract attention for several reasons:
-
Excitement over innovation (e.g., AI, cloud computing, biotech).
-
Influencer hype and media buzz, sometimes based more on storytelling than financials.
-
Investor psychology—especially the fear of missing out (FOMO).
During bull markets, these stocks can rise rapidly in price, giving investors a sense that they’re missing out on “the next big thing.” Unfortunately, that excitement often overrides caution and fundamental analysis. This Forbes article on FOMO explains why investors chase hype.

The Hidden Risks of High-PE Stocks
1. Valuation Risk
High-PE stocks are often priced far above their intrinsic value. When expectations are sky-high, even a small earnings miss can send the stock plummeting.
2. Earnings Volatility
Many high-growth firms haven’t proven consistent profitability. If growth slows—even temporarily—the market can react harshly.
3. Interest Rate Sensitivity
High-PE stocks rely heavily on future earnings. When interest rates rise, the present value of those future earnings drops. That’s why many tech stocks dropped in 2022 when rates increased. Morningstar explains how to interpret PE ratios and avoid overpaying for stocks.

4. Sentiment Over Substance
Investor excitement can drive prices to unrealistic levels. Once sentiment changes, there’s often a sharp and painful correction.

5. Dilution from New Share Issuance
Fast-growing companies often fund operations by issuing new shares, which dilutes existing shareholders. Over time, this can severely impact long-term returns.
Real-World Examples of High-PE Stock Crashes
📉 Peloton (PTON)
Once a pandemic darling, Peloton’s PE ratio was off the charts due to revenue growth. But as demand faded, earnings couldn’t support the price. The stock lost over 90% from its peak.
📉 Zoom Video (ZM)
Another pandemic winner, Zoom had a sky-high PE. But once growth slowed and competitors emerged, the stock retracted dramatically.
📉 Netflix (NFLX)
In early 2022, one earnings report with slowing subscriber growth caused a massive sell-off—proving that even profitable high-PE stocks aren’t immune.

How Value Investors Think About Growth
Warren Buffett is known for avoiding high-flying growth stocks unless he can clearly understand the business model and justify the price. His core principle?
“It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price.”
Value investing doesn’t mean avoiding growth—it means paying a reasonable price for quality and durability. Read Buffett’s 2022 shareholder letter for his latest thoughts on value.

FAQs About High-PE Ratios

Q: Are all growth stocks bad investments?
No. Some growth stocks offer excellent long-term value if bought at the right price.
