84-month Moving Average
The 84-month moving average is a technical analysis indicator used to identify long-term trends in financial markets by averaging an asset's closing prices over 84 months. It helps filter out short-term fluctuations to reveal sustained upward or downward movements.
What is 84-month Moving Average?
The 84-month moving average is a technical analysis indicator that smooths out price data over a period of 84 months, representing seven years. It is used to identify long-term trends in financial markets by averaging the closing prices of an asset over this specific timeframe. By reducing short-term price fluctuations, it offers a clearer view of the underlying direction of an asset’s price movement.
This type of moving average is particularly useful for long-term investors and traders who focus on major market shifts rather than daily or weekly price action. Its extended period makes it less susceptible to noise and more indicative of sustained trends, whether bullish or bearish. Consequently, it can serve as a robust tool for strategic decision-making in investment portfolios.
The 84-month moving average is considered a lagging indicator because it is based on historical price data. Its calculation involves summing the closing prices of an asset for the preceding 84 months and dividing by 84. While this smoothing effect helps filter out volatility, it also means the average will react more slowly to recent price changes compared to shorter-term moving averages.
An 84-month moving average is a technical analysis tool that calculates the average closing price of an asset over the preceding 84 months to identify and confirm long-term market trends.
Key Takeaways
- The 84-month moving average smooths price data over a 7-year period, ideal for identifying long-term trends.
- It is less sensitive to short-term price volatility, providing a clearer view of sustained market direction.
- As a lagging indicator, it reflects historical data and reacts slower to recent price changes.
- Primarily used by long-term investors to gauge overall market sentiment and major trend shifts.
- The average is calculated by summing the closing prices of the past 84 months and dividing by 84.
Understanding 84-month Moving Average
The 84-month moving average represents a significant period in market analysis, often referred to as a ‘seven-year cycle’ in some financial theories. Its extended lookback allows traders and analysts to discern major support and resistance levels that have held over multiple years. A rising 84-month moving average suggests an overall bullish trend, while a declining average indicates a bearish trend.
When an asset’s price is consistently trading above its 84-month moving average, it is generally considered to be in an uptrend. Conversely, trading below this average often signals a downtrend. The interaction between the price and the moving average line can provide signals for potential trend reversals or continuations, although these signals are typically confirmed over extended periods due to the nature of the indicator.
This indicator is particularly useful in identifying the broader economic cycles that influence asset prices. For instance, in equity markets, the 84-month moving average can help investors understand where the market stands within a long-term bull or bear market phase. Its widespread use across many decades of market data lends it a degree of historical significance in trend analysis.
Formula (If Applicable)
The formula for calculating the 84-month moving average is straightforward:
84-Month Moving Average = (Sum of the closing prices for the last 84 months) / 84
Real-World Example
Consider a long-term investor looking at the S&P 500 index. If the 84-month moving average for the S&P 500 is trending upwards and the index is trading above this line, it suggests a sustained bullish environment over the past seven years. For instance, if the average is at 3,500 and the current S&P 500 value is 4,500, this would indicate a strong uptrend.
Conversely, if the 84-month moving average is declining and the S&P 500 is trading below it, such as the average being at 4,000 and the index at 3,000, it would signal a long-term bearish trend. An investor might use this information to adjust their portfolio allocation, perhaps reducing equity exposure during periods when the index is below this significant long-term average.
A crossover scenario might occur if the index price had been below the 84-month moving average for an extended period, and then crosses above it. This would be interpreted as a potentially significant bullish signal, suggesting the start of a new long-term uptrend. However, such signals require considerable price movement and time to develop and confirm.
Importance in Business or Economics
In business and economics, the 84-month moving average provides a vital perspective on long-term economic cycles and market behavior. It helps businesses and economic planners understand the enduring trends in asset valuations, commodity prices, or even broader economic indicators like GDP growth over many years.
For investors, it aids in strategic asset allocation by revealing the stage of a long-term economic cycle. This can influence decisions about investing in growth assets versus value assets or adjusting risk exposure within investment portfolios. Understanding these extended cycles is crucial for mitigating risks associated with market downturns and capitalizing on prolonged upswings.
Furthermore, the 84-month moving average can inform corporate financial planning, mergers and acquisitions strategies, and long-term investment decisions. By looking at trends that span years, companies can make more informed forecasts about market demand, capital availability, and the overall economic climate affecting their industry.
Types or Variations
While the simple moving average (SMA) is the most common, variations exist. An Exponential Moving Average (EMA) gives more weight to recent prices, though for an 84-month period, the difference between SMA and EMA becomes less pronounced. Other, less common variations might involve using different data points or smoothing techniques, but the core principle of averaging over a long period remains.

Frequently Asked Questions (FAQs)
What is the main advantage of using an 84-month moving average?
The primary advantage is its ability to filter out short-term market noise and volatility, providing a clear view of long-term trends that are more indicative of sustained market direction.
Is the 84-month moving average suitable for day traders?
No, the 84-month moving average is generally not suitable for day traders, as its long period makes it too slow to react to intraday price movements. It is best utilized by long-term investors and swing traders.
How does the 84-month moving average compare to shorter-term moving averages?
Shorter-term moving averages (e.g., 20-day or 50-day) are more sensitive to price changes and can generate more frequent signals, but they are also more prone to false signals and whipsaws. The 84-month moving average is less sensitive, provides fewer signals, but these signals are generally considered more significant due to the long timeframe.
