The Short Version
When interest rates go up, the present value of future earnings goes down. Growth stocks — companies valued primarily on future earnings — get hit hardest. It's not sentiment. It's math.
How Discounted Cash Flow Works
Every stock price is theoretically the sum of all future cash flows, discounted back to today's dollars. The discount rate is heavily influenced by the "risk-free" rate — which is basically the 10-year Treasury yield.
When rates rise from 4% to 5%: - A dollar of earnings expected 10 years from now is worth less today - The further out those earnings are, the bigger the hit - Growth stocks (NVDA, TSLA, etc.) derive most of their value from earnings 5-10+ years away - Value stocks (JPM, XOM) earn most of their money now — less affected
Why the Nasdaq Drops on Fed Hawkishness
The Nasdaq is heavily weighted toward technology and growth companies. When the Fed signals higher rates:
- **Bond yields rise** — the 10-year Treasury becomes more attractive
- **Discount rates increase** — future earnings are worth less in today's dollars
- **Growth stock valuations compress** — P/E ratios contract
- **The Nasdaq drops disproportionately** — because it's packed with long-duration assets
This is why you'll see the Nasdaq fall 2-3% on a hot CPI print while the Dow barely moves 1%.
What This Means for Your Portfolio
If your portfolio is heavy in technology (like 68% of the demo portfolio on this platform), you have significant rate sensitivity. Here's how to think about it:
- **Rising rate environment:** Your tech-heavy portfolio will face headwinds. Consider whether your conviction in each holding's growth thesis is strong enough to ride it out.
- **Falling rate environment:** Growth stocks tend to outperform. Your portfolio is positioned to benefit.
- **Flat rates:** Stock-picking matters more than macro. Focus on individual company fundamentals.
The key insight: rate sensitivity isn't binary. It's a spectrum. A company growing revenue 40% per year (like NVDA) can absorb higher rates better than one growing 10% — because the growth overwhelms the higher discount rate.
The Bottom Line
Don't panic-sell growth stocks every time the Fed sounds hawkish. Instead, understand your portfolio's rate sensitivity, monitor the 10-year Treasury yield, and make sure your holdings have strong enough growth to justify their valuations even in a higher-rate world.
