The simple moving average (SMA) method, a cornerstone in financial analysis, warrants a closer examination of its formula, strategies, and versatile applications. Offering a straightforward yet effective approach, the SMA method proves invaluable for investors and traders alike, providing insights into trend analysis, decision-making strategies, and a nuanced understanding of market dynamics. This exploration caters to a broad audience, from novices seeking a fundamental grasp to seasoned traders looking to harness the power of the SMA in navigating the ever-evolving landscape of financial markets.

Defining Simple Moving Average

The simple moving average is a moving average. It is produced by averaging prices or values across a set number of days or intervals. It is utilised in the financial sector as a technical indicator. The SMA line, formed by the average or SMA values displayed in a chart of asset prices, moves when fresh average values are drawn. Trading professionals may examine price changes and spot patterns and choose appropriate entry and exit points by applying SMA to asset prices based on a chosen range.

Working of Simple Moving Average

  • The simple moving average is computed by averaging prices over a specific period, readily available on financial websites and trading apps.
  • Experienced traders often utilise the simple moving average in trend-following strategies, buying stocks on an upward trend and selling those on a downward trend.
  • A rising moving average signals an upward trend, with stronger trends indicated by higher shorter averages.
  • To validate a robust trend, the stock price should be above the 50-day SMA, which, in turn, should surpass the 200-day SMA.
  • Trend-following, considered one of the most effective trading techniques, has shown historical success across various asset classes.
  • Moving averages, recognised as lagging indicators for confirming trend changes, may close the window of profit opportunity if the stock price is already higher than the historical moving average.
  • Some traders prefer monitoring price crosses, especially crossovers where a lower-number average surpasses a higher one, providing entry signals for potential trades.
  • For instance, a trader might consider purchasing when the 50-day moving average crosses over the 200-day moving average, indicating a potential uptrend.

Uses of Simple Moving Average

The simple moving average is computed by adding all data points and dividing the total by the number of data points. For example, a 50-day simple moving average calculates the average closing price of the most recent 50 days by summing the closing prices and dividing by 50. As new data points emerge, the oldest period is excluded from the calculation to update the moving average.

Simple moving averages of 10, 50, and 200 days are commonly used as default indicators for short-, medium-, and long term trend analysis. They identify price patterns over specific periods, adaptable to various time frames, such as the last 5 or 10 minutes on an intraday chart or a day and week on a yearly chart.

The duration of the moving average influences its sensitivity to new data points, with longer periods requiring more time for changes in the underlying asset’s price to impact the average value. Longer timeframes decrease the likelihood of a single data point producing a misleading signal of a trend change.

Calculating Simple Moving Average

The simple moving average is a mathematical moving average created by adding recent prices and dividing that total by the number of periods in the computed moving average. In the closing instance, the share price may be added up over several periods and then divided by the same number of periods; in contrast to the long term average, which responds more slowly to changes in the underlying security price, the short term average does so swiftly. Different varieties of moving averages exist, such as weighted moving averages (WMA) and exponential moving averages (EMA).

The simple moving average formula is: SMA = A1+A2……A /n

The starting data point for the day-day moving average will be the average of the first ten days’ closing prices. The same is true for a 50-day moving average, where the SMA gathers data for 50 consecutive days to produce an average.

The simple moving average may be calculated over several periods, making it configurable. The stock’s average price over the period is calculated by adding the closing prices of the security across several periods, dividing the total by the number of periods, and then averaging the results. A simple moving average reduces volatility and makes seeing a security’s price trend easier.

When the asset’s price increases, the simple moving average goes upward. Conversely, a moving average sloping downwards indicates a declining security price if it is trending downward. The smoother the simple moving average, the longer the period for the moving average.

Trading Strategies Using Simple Moving Average

When the price briefly reverts to the 50 EMA after a period of divergence, it signals compelling trading opportunities. This phenomenon indicates a potential emergence of trending price activity, a concept familiar to investors who closely monitor moving averages. In contrast, moving averages often converge during sideways price movements, getting entangled with the ongoing live activity and posing challenges for moving average-based systems. To mitigate this, a trader should focus on the price touching the 50 EMA after spending a considerable time away from it, as this marks the initiation of a promising trend, serving as a clear filter for potential account-impacting issues.


The SMA method is a fundamental tool in financial analysis, calculated by averaging prices over a specified period. Traders employ various strategies utilising SMAs, such as the Crossover Strategy, identifying trends through the Golden Cross and Death Cross, and confirming trends with the Trend Confirmation Strategy. This versatile method is widely used for trend analysis, entry/exit decisions, and overall market assessments, making it an essential component of traders’ toolkits.
