Principal-Driven Investing — How I'm Handling Intel ($17 → $110) and AMD

When the market is overheated, the hard part isn't analysis — it's behavior. Prices rise and you want to add more; prices fall and you want to capitulate. To fight that instinct I keep coming back to five tenets. The cleanest live case study right now is the semiconductor sector — specifically Intel and AMD.

The five tenets

Tenet 1. We are investors, not speculators

Buying at record valuations can feel like speculation. But if you're dollar-cost averaging while explicitly accepting that the next 10–15 years may underperform history, that's still investing. The intent matters: long-term ownership of business cash flows is different from trying to ride a price move.

Tenet 2. Every investment is the present value of all future cash flows

Stocks, real estate, any asset — intrinsic value equals the sum of every dollar of cash the asset will ever produce, discounted back to today. That's it. Elon's tweets don't change value. "How much cash will this business generate over its lifetime?" is the starting point. The less you pay for that stream, the higher your return.

Tenet 3. If we don't understand it, we don't invest in it

If you can't explain how a company makes money in plain English, you have no business owning it — no matter how exciting the story or how smart the buyers.

Tenet 4. Short term: voting machine. Long term: weighing machine

Ben Graham's line. Near term, the market votes — Twitter, headlines, fear, FOMO move prices. Over years, it weighs — fundamentals determine value. Buy a reasonable business at a reasonable price, let earnings grow 10× over 20 years, and the stock roughly follows.

Tenet 5. A great story becomes a bad investment if you pay the wrong price

This is the one that matters most. Brilliant CEO, real product, real growth — and you can still lose money if you overpay.

Case 1: AMD — great company, dangerous price

AMD is a fantastic business. Competitive silicon, strong execution, a data-center segment growing in leaps. The story is real.

The price is the problem. AMD currently has years of perfect execution priced in. Any quarter where growth slows, any quarter where a competitor takes a slice of share — the stock has setup to fall 50%, 60%, 70%. We've seen the same pattern repeatedly: real business + perfect-future price = speculation, not investment. The whole bet is "everything has to go right."

Case 2: Intel — a stock I actually own

Intel is personal. I own it. For a long stretch my comment section was filled with "why on earth do you hold this?"

Entry: About a year ago at roughly $17. Intel had lost its manufacturing edge, earnings were broken, the stock was down ~80% from its 2000 peak of $75. The market treated it as dead. I bought because the price had fallen below what I thought the underlying franchise was worth.

Now: Closed yesterday near $110. About a 6.5× move.

My view today: I said the stock wasn't worth $20 on the way down — and I have to be consistent on the way up. It isn't worth $110 either, by my model. Running the business through our stock analyzer, fair value sits closer to $50. Revenue is still way down, free cash flow and net income are negative. The turnaround is real, but it isn't finished and the price has gotten ahead of it.

How that translates into action

• Not panic-selling: The franchise is real, the turnaround is in motion. I'm not capitulating to the urge to lock in gains just because they exist.
• Not adding: This is the discipline. Tenet 5 doesn't have an exception clause. I bought below value; price has moved above value; that means I don't add more.
• Five years out, gun to my head: I'd guess lower than today. I don't know that — that's why I'm not selling — but I'm certainly not paying up.

The bigger lesson: price moves fast, value moves slow

The market runs on two time clocks. Price jumps daily; value accumulates quarter by quarter. The job is to buy when Mr. Market is irrationally depressed, and to not buy when he's irrationally excited.

Semiconductor demand is real. AI capex is real. But inside a broadly overheated market, several chip names have priced in much more "real" than the earnings can deliver. Refusing to pay the wrong price for a great story — that is the entire game.

FAQ

Q: Should I sell Intel here? A: I'm not. A position bought below value doesn't have to be liquidated the moment it crosses fair value. I'm holding without adding. "Hold" is the most boring and usually most rational action.

Q: Is AMD a buy at current prices? A: The business is excellent. The price requires multiple years of flawless execution to justify. I'd run it through a fair-value model — if the gap isn't wide, pass.

Q: Which of the five tenets matters most? A: Tenet 5. You can follow the first four perfectly and still destroy returns by overpaying. Price discipline is what carries the whole framework.
