Open any stock forum and you'll see comments like this everywhere: "It's already up so much, way too expensive to buy now," or "It broke $200, I'll wait for a pullback." The reaction is natural — seeing a number far higher than what you remember, the first instinct is "expensive."
But that instinct conflates two completely different things: price and value. Price is the number on your screen. Value is what the company is actually worth. The two should line up, but in practice, price can be almost any number — it depends entirely on how many shares a company has issued, which has nothing to do with what the company is actually worth.
A $750,000 Share — Is That Expensive?
If that sounds abstract, consider the most extreme real example there is. Berkshire Hathaway's Class A shares currently trade above $750,000 per share — no typo, seven hundred fifty thousand dollars. Looking at that number alone, it should be one of the most expensive stocks on earth.
But Berkshire's P/E ratio is only around 15 — hardly "expensive" compared to most large companies. The reason is simple: Berkshire has deliberately never split its A shares. Buffett's intent was to keep the share price high enough that it wouldn't attract frequent trading, favoring investors who plan to hold for the long term. The price is an astronomical number, but the value — what you're paying relative to the company's earning power — is nothing unusual at all.
The reverse is just as true. A stock priced at $10 a share can easily carry a sky-high P/E ratio if its earnings power is weak, making it a genuinely "expensive" stock in every sense that matters. A low price doesn't mean low value.
So What Does "Expensive" Actually Mean?
If price alone can't tell you whether something is expensive, what can? The answer: divide the price by some measure of the company's earning power, then compare that ratio against the company's own historical range.
Think of it like judging whether a house is expensive. You wouldn't look at the total price alone — you'd look at the price per square foot, then compare that figure to what similar homes in the same neighborhood have sold for in recent years. Stock valuation works the same way: what matters isn't the price itself, but the price relative to earning power, compared against the company's own historical range.
Once you see it this way, you'll notice most retail judgments of "expensive" rest on a few common misconceptions: buying something just because the number looks cheap, without understanding the business, then panic-selling the moment it drops because there was never any real conviction behind the purchase; assuming there's a single "universal ruler" that works for every company, forgetting that growth companies and stable dividend payers need entirely different metrics; and — the one most often overlooked — every valuation number needs context. The same ratio means wildly different things across industries and across a company's own historical range. There's no universal magic number where "above this is expensive."
A Few Basic but Useful Valuation Metrics
With that logic in mind, here are a few common ways to calculate "price ÷ earning power." The most basic is the P/E Ratio — price divided by earnings per share over the trailing 12 months. It's the most widely used and easiest to understand, but it only looks backward, ignoring a company's future growth. That's why Forward P/E (using projected future earnings) and PEG Ratio (factoring in growth rate) exist as extensions to compensate for that blind spot.
A metric that's gained more attention in recent years is Price-to-Free-Cash-Flow (P/FCF): price divided by free cash flow per share. This directly reflects the cash a company actually has available to use, and it's harder to manipulate than earnings figures, which can be shaped by accounting choices. It's a particularly reliable reference for companies with volatile cash flow or those in heavy capital investment phases.
Same All-Time Highs, Opposite Value Signals
Back to the original question: does a stock hitting an all-time high mean it's expensive? Here's a real comparison. NVIDIA trades above $200, Apple above $300 — both hit record highs over the past year. Looking only at "new highs," it's easy to assume both are now "expensive." But using P/FCF and placing each company against its own five-year historical range tells a completely different story.
NVIDIA's current P/FCF is around 41.5x — which happens to be the lowest point in its own five-year range. In other words, despite repeatedly hitting new highs, NVIDIA's value by this measure is actually at its relatively "cheapest" point in five years, because earning power has grown even faster than the stock price.
Apple's current P/FCF is around 35.6x — lower than NVIDIA's 41.5x at first glance, which might suggest it's "cheaper." But placed against Apple's own five-year range (21.9x to 38.7x), 35.6x is actually very close to the top of that range, putting it in relatively expensive territory.
If you only compare the two raw numbers (41.5 vs. 35.6), you'd conclude Apple is cheaper. But placing each number back into its own historical context flips the answer entirely — NVIDIA is sitting near its cheapest point in five years, while Apple is near its most expensive.
Value Is Something No Systematic Approach Can Ignore
Dollar cost averaging doesn't require you to precisely judge whether something is expensive right now — that's its core strength, buying on a fixed rhythm specifically so you don't have to be right about timing every time. But that doesn't mean value can be ignored. Any method that tries to systematically evaluate "should I add to my position now" while completely disregarding a company's value — looking only at price momentum or market sentiment — tends to run into trouble over time. It can mean disciplined, regular buying into an asset whose value is quietly eroding, or passing on a genuinely good company simply because its price hit a new high, when its value was actually sitting in fair or even cheap territory — like Berkshire, or NVIDIA in this example.
That's also why an increasing number of tools built around this kind of systematic evaluation — DCAcafe included — treat valuation level as an essential input, not an afterthought. Price tells you how the market currently views a company. Only by placing that price back into the context of value can you tell whether that view is reasonable, or overextended. This isn't any one tool's proprietary insight — it's a step no serious attempt to factor valuation into decision-making can skip.
Next Time You See "Stock Hits New High"
Whether something is "expensive" was never a question price alone could answer, and it was never a question with one universal answer either. It requires understanding the company first, choosing the right metric, and finally placing the number back into its own historical context. Next time that instinctive reaction hits — "it's at a new high, must be too expensive" — it might be worth pausing to ask: am I talking about price, or value?
