CONCEPT

What a moving average is (and what it actually does)

It's the most widely used indicator in the world. It smooths out the price noise and reveals the underlying direction.

WHAT IT DOES

smooths

the daily noise

THE SHORT ONE

MA50

medium term

THE LONG ONE

MA200

long term

THE IDEA

MA

the average of the last N closes, recalculated daily

A moving average averages the price over the last sessions (say, 50 or 200) and draws a smooth line. Because it updates every day, it moves with the price: that's why it filters the noise and lets you see the underlying trend.

EXAMPLE

SIMPLE RULE

50

50

sessions averaged in the MA50

Fifty days of price summed into a single point, every day. Connect those points and you have a line that tells the trend without the noise.

The 50-day average covers about two and a half months of trading. It's the most-watched medium-term reference.

MA50
50-day moving average: the medium-term trend filter.
MA200
200-day moving average: the long-term trend.

PRINCIPLE

TO GET IT

The average doesn't predict, it organizes

Price is the noise; the moving average is the signal. It doesn't look at the future: it tells you whether the tide is rising or falling now.
Ronfy Analysis · Editorial

A moving average won't tell you what happens tomorrow. It tells you which trend you're in today, and that's already a lot.

SIGNAL
The useful information left once you filter out the noise.
FILTER
Removing small moves to see what matters.

ILLUSTRATION

HOW IT LOOKS

Price bouncing off its average

While price leans on the average and bounces, the trend rules. Losing it clearly is the first sign of a change.

Illustrative example, not real data. While the trend is up, price tends to lean on its moving average and bounce.

DYNAMIC SUPPORT
The moving average acts as a support that moves with the price.
BOUNCE
When price touches a level and turns back up.

WHAT IT'S FOR

THREE USES

Three things a moving average does for you

  1. IT DEFINES THE TREND

    If price is above its average and the average is rising, the trend is up. Below and falling, it's down. A single glance that saves a thousand doubts.

  2. IT ACTS AS SUPPORT OR RESISTANCE

    In healthy trends, price leans on its average (support) or stalls at it (resistance). It's a level that moves with you, not a fixed one.

  3. IT GIVES CROSSOVER SIGNALS

    When the short average crosses above the long one it's a 'golden cross'; the reverse is a 'death cross'. Slow signals, but followed by many.

Beyond drawing a nice line, the moving average serves three very concrete purposes.

RESISTANCE
A level where price tends to stall on the way up.
GOLDEN CROSS
The short average crosses above the long one: a classic bullish signal.

EXAMPLE

TYPES

The most-watched moving averages

MA200 (LONG TERM): 40%MA50 (MEDIUM TERM): 35%MA20 (SHORT TERM): 25%ATTENTIONMAs
MA200 (LONG TERM)The big bull/bear filter for the year40%
MA50 (MEDIUM TERM)The most-used trend reference35%
MA20 (SHORT TERM)Reacts fast, more noise25%

The longer the average, the slower and more reliable as a trend. The short one reacts sooner but gets it wrong more often. Figures are illustrative.

Not every average carries equal weight. These are the ones pros watch most, by horizon. Illustrative split of attention.

HORIZON
The time span the average sums up (20, 50, 200 days).
RELIABLE
Giving fewer false signals, even if later.

WHERE YOU SEE IT

5 EXAMPLE ETFs

Five ETFs where the moving average is watched daily

SPY~720 ref.S&P 500. Its MA200 is one of the most-watched lines in the world.
QQQ~590 ref.Nasdaq-100. Tech: the MA50 marks its medium-term trend.
IWM~230 ref.Small caps. They tend to lose the average before the big indices do.
DIA~440 ref.Dow Jones. A steadier trend, cleaner averages.
VTI~300 ref.The whole US market. Useful to read the underlying trend of the lot.

Evergreen concept: these broad ETFs are the ones most traders track with the MA50 and MA200. Rounded example prices.

ETF
A listed basket tracking an index, bought like a stock.
ROUNDED
An approximate example price, not the day's real quote.
