What it means
The starting assumption is that prices move in trends driven by the collective behaviour of buyers and sellers, and that those trends leave recognisable traces on a chart. A technical analyst therefore spends time on moving averages, support and resistance levels, and momentum indicators rather than on annual reports.
The claim is not that fundamentals are irrelevant, but that the market has already priced them in. For a non-finance manager the relevance is mostly indirect but real.
Share prices, commodity prices and exchange rates all have a large population of technically driven traders, so a currency move or a spike in your input costs can happen for reasons that have nothing to do with supply and demand in your industry. The most common tools are simple.
Moving averages smooth out daily noise to show the underlying direction, support and resistance mark price levels where buying or selling has repeatedly appeared, and relative strength indicators flag when a move has gone unusually far in one direction. Technical analysis is genuinely contested, and it is worth saying so plainly.
Academic studies of market efficiency argue that past prices cannot predict future ones, while practitioners point to the self-fulfilling effect of thousands of traders watching the same levels and acting on them at the same time. The practical middle ground taken by most professional investors is to use fundamentals to decide what to buy and technicals to decide when.
A treasury team hedging a foreign currency exposure might set the size of the hedge from the business plan and the timing from the recent trading range.
In practice
Real-world examples.
Example
A treasurer at an importer needs to buy euros over the next quarter. She uses the business forecast to fix the amount but times the purchases around a 50 day moving average, buying more heavily when the rate dips below it.
Example
A commodities buyer for a bakery notices wheat futures have broken above a price level that stopped three previous rallies. Expecting further buying from trend followers, he brings forward part of his forward purchasing rather than waiting for the usual quarterly cycle.
Example
An investor relations manager fields calls asking why the share price fell 6% on a day with no company news. The answer is that the stock closed below a widely watched support level, triggering automated selling from momentum funds.
Think of it
“Technical analysis is like reading a patient's vital signs chart without knowing their medical history-you're looking at patterns in the data.
Formula
Calculation
Simple moving average = Sum of closing prices over N periods / N
Take a share whose closing prices over five trading days were $42, $44, $43, $47 and $49. The sum is $42 + $44 + $43 + $47 + $49 = $225, so the five day simple moving average is $225 / 5 = $45.
On the sixth day the price closes at $51 and the oldest figure, $42, drops out of the window. The new sum is $225 - $42 + $51 = $234, giving a moving average of $234 / 5 = $46.80. The average has risen while the latest close sits above it, which a technical analyst would read as a short term uptrend.Case study
Seen in the real world.
The following is an illustrative and entirely fictional example. Calderwood Metals, an invented specialist alloy producer, published strong half year results and watched its share price fall 9% over the next fortnight. The chief executive was convinced investors had misread the numbers and pushed for an unscheduled trading update.
The company's broker offered a different reading in this fictional scenario. The results had come in almost exactly where the market expected, and the fall coincided with the share price slipping through a level it had bounced off three times in eighteen months, prompting selling from funds that trade on price signals rather than earnings.
Calderwood's illustrative board decided against the emergency update and instead brought forward a planned investor roadshow. The point they took away was not that technical analysis is correct, but that a share price move over two weeks is a poor guide to whether a set of results was well received.
Watch out
Common mistakes.
- Treating a chart pattern as a prediction rather than a probability, and sizing a position as though the outcome were certain.
- Adding indicator after indicator until several of them agree, which usually means they are all measuring the same thing rather than confirming each other.
- Applying technical signals designed for liquid markets to a thinly traded small company share, where a handful of orders can create a pattern that means nothing.
Questions
People also ask.
Does technical analysis actually work?
The evidence is mixed and heavily debated, which is why most professional investors treat it as a timing aid rather than a standalone strategy.
What is the difference between technical and fundamental analysis?
Fundamental analysis asks what a business is worth from its financial performance, while technical analysis asks where the price is likely to go next based on price and volume history.
Should a company's management pay attention to its own chart?
Only lightly, since day to day price action rarely reflects operating reality, though sustained trends are worth understanding before an equity raise.
