Advances and Declines

Advances and Declines

What Are Advances and Declines?

Advances and declines alludes generally to the number of stocks (or different assets in a specific market) that closed at a higher and those that closed at a lower price than the previous day, separately. Technical analysts take a gander at advances and declines to examine stock market behavior, recognize volatility, and foresee whether a price trend is probably going to proceed or reverse.

Commonly, a market will be more bullish in the event that a greater number of stocks advance than decline and vice versa throughout some time span.

Figuring out Advances and Declines

Advances and declines form the basis of various technical indicators, including the advance-decline ratio, the advance-decline index, and the absolute breadth index. For instance, a low advance-decline ratio can demonstrate a oversold market, while a high advance-decline ratio can signal a overbought market.

Both of these conditions could mean that a market trend has become impractical and is going to reverse.

Periodically, traders consolidate the advances and declines indicators with different forms of technical analysis. A great model would be taking a gander at momentum indicators, similar to the relative strength index (RSI) or moving average combination divergence (MACD) for a divergence, and afterward viewing at advances and declines as a confirmation that a trend change is beginning to happen.

Advances and Declines Indicators

There are various technical indicators that are calculated utilizing advances and declines:

  • Advance-decline ratio: The advance-decline ratio, or ADR, compares the number of stocks that closed higher against the number of that closed lower during a specific period (and can be utilized across numerous time periods).
  • Advance-decline index: The advance-decline Index, or ADI, is a market breadth indicator that addresses the total difference among progressing and declining securities inside an index. Sometimes, the current index level is addressed as a horizontal line on a price chart known as the advance-decline line.
  • Absolute breadth index: The absolute breadth Index, or ABI, is a technical indicator that depends on the differences among advances and declines on an index. Not at all like the prior two readings, the ABI overlooks where that prices are heading and on second thought centers absolutely around the differences to measure volatility.

These indicators are generally deciphered similarly: Rising values will more often than not demonstrate a bullish market and falling values will quite often show a bearish market. For instance, the above chart shows a rising advance-decline line perusing among December and mid-January, which suggested that advances outperformed declines during the uptrend.

The main exception is the ABI, which measures just volatility and not course. In many cases, the ABI is deciphered by taking a moving average of the perusing and searching for critical trends, which can show rising and falling volatility trends.


Below is an illustration of the advance-decline line for the S&P 500 SPDR ETF (SPY) as it appeared in May 2018. It shows up as the blue line graph plotted below the candlestick chart.

As may be obvious, the number of advances relative to declines is expanding through May, when it arrives at a maximum, maybe showing a bull rally to come soon. For sure, as we presently know, the market rose through the last part of 2018 and into 2019.


  • Rising values for advances and declines indicators are many times a technical signal of a bullish market while declining values address a bearish market.
  • Advances and declines data form the basis of several technical indicators that address market dynamics and can be utilized related to different forms of technical analysis of stocks.
  • Advances and declines are the extent of stocks that closed at a higher versus a lower price as compared to the previous trading day.
