Fórmula

## How to Calculate a Simple Moving Average ### Formula **SMA(n) = (v1 + v2 + ... + vn) / n** The simple moving average smooths data by averaging the most recent n observations. As new data arrives, the oldest point drops off and the newest is added. SMA reduces noise and reveals underlying trends in time-series data.

Ejemplo Resuelto

Daily sales: 10, 12, 15, 14, 18. Calculate the 5-day moving average.

  1. 01Sum = 10 + 12 + 15 + 14 + 18 = 69
  2. 025-period SMA = 69 / 5 = 13.8
  3. 033-period SMA (last 3) = (15 + 14 + 18) / 3 = 15.6667

Preguntas Frecuentes

What period should I use for the moving average?

Shorter periods (3-5) respond faster to changes but are noisier. Longer periods (20-50) are smoother but lag behind trends. In finance, 50-day and 200-day SMAs are standard. Choose based on your need for responsiveness vs. smoothness.

What is the difference between SMA and EMA?

SMA weights all periods equally. Exponential Moving Average (EMA) gives more weight to recent data, making it more responsive to new information.

Can moving averages predict the future?

Moving averages describe past trends but do not predict future values. They are lagging indicators. Crossovers between short and long SMAs are used as trading signals but are not guaranteed predictors.
