These two disagree less often than the arguments suggest, because they are rarely answering the same question. One is about what a business earns and is worth; the other is about how its price is behaving this week. Measured on the companies in the Dow today, earnings and price moved together loosely over a single year and much more closely over five or ten, which is the whole case for keeping them on separate horizons.

What each one is

Fundamental analysis reads financial statements: revenue, margins, debt, cash flow and earnings per share, turned into a view about what a business is worth. Fundamental analysis covers it.

Price action reads the bars themselves: swing structure, ranges, breaks and the shape of individual candles, with no reference to the company at all. Price action covers it, and technical analysis is the larger family it sits in.

The inputs do not overlap. Most comparisons on this site set two readings of the same price series against each other. These two read entirely different things: one a set of filed documents that arrive four times a year, the other a sequence of prices that updates every session.

Where they differ

What timescale each operates on. A fundamental view resolves as earnings arrive and are priced, which takes years. A price action reading resolves in days. Both can be correct about the same company at the same moment, one about the business and one about this week’s order flow.

What each can see. Accounts reveal a company borrowing heavily, losing margin or running short of cash. A chart shows none of that until it moves the price, and by then the information is no longer news to anyone holding the filings.

What each cannot tell you. Fundamentals carry no date: a company can stay cheap for years. Price action carries no verdict on the business: a strong company and a failing one can print the same pin bar on the same day.

How each one is checked. A fundamental view is checked against the next set of reported earnings, which either arrive or do not. A price action reading is checked against the next few bars, and the same bar can confirm one trader’s read and refute another’s.

How closely earnings and price move together, by horizon

The question this page can answer with data is whether the businesses’ earnings and their share prices actually move together, and over what span. If they move together over years but not over months, then the division of labor below is not a matter of taste.

Over single years the link is loose. Ranking every company-year by its change in diluted earnings per share and by its change in share price, the two rankings agree only weakly: a rank correlation of 0.31 across 436 company-years in which earnings were positive at both ends.

Over five and ten years it is much tighter. Taking each company’s latest window, the same rank correlation was 0.43 for one year, 0.63 for three, 0.72 for five and 0.65 for ten. Companies that compounded earnings fastest over a decade were, with exceptions, the ones whose shares rose most.

Exceptions are real. IBM’s diluted earnings per share fell 16.8% over its ten fiscal years to December 2025 while its share price rose 125.1%. Microsoft’s earnings per share grew 7.13 times over its ten years to June 2026 and its price 7.29 times. Both are in the same index, and only one of them looks like the textbook.

Which one to use: Fundamental Analysis or Price Action?

Use fundamental analysis when the holding period is years. Over that span what the business earns is most of what the measurement above found to matter, and the daily path of the price is noise you will sit through.

Use price action when the holding period is days. Over that span nothing in the accounts changes, so they have no bearing on whether this week’s breakout holds.

Use fundamentals to choose and price action to time. That is a genuine division of labor: one input picks the company, the other picks the entry and the price at which the entry is wrong.

And when they conflict, notice which horizon you are on. A cheap company falling for six months is not a contradiction. It is two true statements about different periods.

Why the argument is usually a category error

Because value and price are allowed to differ for a long time. That gap is the premise of value investing, so a fundamental analyst is not embarrassed by a falling price, and a chart reader is not obliged to hold an opinion about earnings.

And because only one of them can see a company weakening. A chart shows a decline. The filings show whether it is a discount or a warning, and no amount of bar reading substitutes for that.

The original data

The companies. State Street’s holdings file for its Dow Jones Industrial Average ETF (DIA), dated 1 October 2026, lists 30 stocks; Visa is left out because its SEC EDGAR company facts carry no standard diluted earnings-per-share figure. These are the index’s current members, so every one of them is a company that did well enough to be in the Dow today. That survivorship almost certainly flatters how well earnings and price lined up, because companies whose earnings and shares both collapsed were removed from the index and are not in the sample.

Earnings. Diluted earnings per share from each company’s annual 10-K filings, via the SEC’s XBRL company facts. Each yearly change pairs the two figures one 10-K prints side by side, this year and last, so a stock split between filings cannot distort it. Longer windows chain those yearly changes and are used only where earnings stayed positive throughout: six companies had a loss year inside their latest ten, and three had gaps or too short a record in the SEC data, leaving 20 for the ten-year figure, 24 for five, 26 for three and 28 for one.

Prices. Yahoo Finance daily closes, adjusted for splits but not for dividends, taken on the final trading day of each fiscal year or the nearest one before it. Dividends are left out on purpose: the comparison is earnings against the share price, not against total return.

How sure. With a shuffle test (200,000 random pairings), a five-year correlation that strong arose by chance in about 1 in 10,000 tries and a ten-year one in about 1 in 400. That says the link is not noise in these 20 to 28 companies; it does not say it holds for companies that left the index. Even over the latest single year, earnings and price moved the same direction for 22 of 28 companies (78.57%). The full company-year table is the Dow earnings and price file, and every window in the window file.

When it fails

The characteristic failure is using fundamentals to justify holding a losing trade. A position taken on a chart reading goes against you, and rather than accepting the stop the trader reaches for the company’s accounts, which were not the reason for the entry and are being recruited afterwards to avoid a decision. The valuation may even be sound, and it is irrelevant, because the position was sized for a days-long horizon and is now being held on a years-long argument with no change to the risk. The single-year correlation above is the reason this goes wrong so often: over a few months, good earnings and a rising price are only loosely connected.

A second failure is the reverse: abandoning a long-term holding on a chart signal that operates over days.

A third is expecting price action to reveal a weakening business, which it cannot do until the decline is already under way.

A fourth is expecting fundamentals to provide timing, which they do not claim to do.

And a fifth is reading the long-run fit as a promise. It was measured on survivors, after the fact.

Fundamental analysis covers reading the accounts and what a filing contains. Price action covers reading the bars and the swing structure. And technical analysis is the broader school of chart reading that both camps argue over.
