Fundamental Analysis vs Technical Analysis
Fundamental analysis estimates what a business is worth from its financials; technical analysis reads what price has done. They answer different questions on different horizons, and only the technical side produces a specific price at which the idea is wrong.
The oldest argument in the subject, and mostly a false one. Fundamental analysis asks what a business is worth. Technical analysis asks what price is doing. Those are different questions, so the answer is rarely which is better — it is which question your horizon requires.
What each one is
Fundamental analysis estimates worth from the business. Revenue, margins, cash flow, debt, and a judgement about the future turned into a number. Fundamental analysis covers the approach.
Technical analysis reads what price has done. Levels, trends, ranges, volume — on the argument that price already reflects what participants collectively know. Technical analysis covers it.
Neither claims to predict. The honest version of both is a framework for making a decision under uncertainty, and both are wrong regularly.
Where they differ
Horizon. A valuation resolves over years. A level resolves over bars. Applying one on the other’s timescale is the single most common way either gets misused.
Whether it produces an invalidation. A chart level gives a specific price at which the idea is wrong, which is what sets position size. A valuation does not — “cheaper” is not a stopping rule, and a cheap company can get cheaper for years.
What being early costs. Fundamental work is frequently right and early, which on this site’s shared series looks identical to being wrong: 95% of bars sat below a prior peak and the longest recovery took 73 bars.
What the inputs are. One reads filings that arrive quarterly; the other reads a price that updates continuously. That difference in refresh rate is most of why the horizons differ.
Where they agree
Both are backward-looking. Filings describe a period that ended; charts describe bars that closed. Neither has access to the future and both are frequently presented as though they do.
Both require a written rule to be reviewable. A valuation with no stated assumption and a chart pattern with no stated definition fail the same way — neither can be shown to have been wrong.
And both are worthless without position sizing. Whichever framework produced the idea, the amount at risk comes from the same arithmetic: risk figure divided by distance to invalidation.
Which one to use
Use fundamental work when your horizon is years and you can hold through being early. Owning a business for a decade needs a reason a chart cannot supply, and the volatility along the way is the price of that horizon.
Use technical work when your horizon is days or weeks. Over that window nothing in the accounts has changed, so the only information available is what price is doing — and you need an invalidation, which only the chart provides.
Use both when you hold for months, with fundamental work choosing what to own and technical work choosing when to buy it. That combination is common and it needs one rule.
That rule is: when they disagree, the shorter horizon wins on timing and the longer one wins on selection. Deciding it in advance is what stops the disagreement being resolved by whichever answer you preferred.
What neither can do
Neither tells you when. A valuation is a claim about worth with no date attached. A level says something might happen here, not that it will, and not this week.
Neither sees liquidity. A cheap company you cannot buy at size and a clean level on an untraded instrument are the same problem, and both frameworks are silent on it.
The original data
Of the 24,971 unique videos in research/search-study-corpus.jsonl, 24 compare the two directly in
the title, at a median of 23,862 views across 4 distinct phrasings. Separately, fundamental analysis
appears in 49 titles at a median of 7,377 and technical analysis in far more. The counts come from
site/rank_compare.py and site/corpus_count.py.
24 comparison videos at 23,862 against 49 on fundamental analysis at 7,377. Half the coverage and three times the audience per video — the argument between them reaches more people than either framework does on its own, which is a fact about how the subject is taught rather than about the methods.
The answer to the question on that chart is that your rule decided it before you looked. Without one, the framework that gets followed is the one agreeing with the position you already wanted — and that is not a method, it is a preference with two vocabularies available to justify it.
When it fails
The failure is switching frameworks to avoid an exit, and it is available to anyone who knows both. A technical trade goes against you, the level breaks, and the stop should fire — but the company is cheap on the numbers, so the position becomes a long-term hold. Nothing was reassessed; a short-horizon trade with a defined invalidation was converted into a multi-year position with none, at the exact moment the original rule said to leave.
The second failure is applying a valuation on a weekly horizon. Nothing in the accounts changed.
A third is expecting a chart to tell you what something is worth. It has no such input.
A fourth is holding a fundamental view with no invalidation. Cheaper is not a stopping rule.
A fifth is no rule for disagreement. The preferred answer then wins.
And a sixth is treating either as predictive. Both describe what has already happened.
Related
Fundamental analysis covers the business side. Technical analysis covers the price side. And combining the two covers using both without letting either rescue the other.
The practical difference is that only one of them has ever told me where I was wrong. A valuation says a company is worth more than the price; it does not say what would prove that judgement mistaken, or when. A level does both, which is why the sizing arithmetic runs off it.
