## What is the Advance-Decline Ratio?

Advance-Decline Ratio is a technical analysis about the stock market trends on the basis of which the nature of market securities are analyzed like whether the securities are bought in excess or sold in excess in order to determine whether the market is growing positively or negatively and it can be calculated on daily, fortnightly, monthly, quarterly or for any period as per requirement or type of investor.

### Explanation

It is the analysis of the market securities, which helps the investor to decide whether to buy the securities or sell the securities. The advance-decline ratio, if used with other parameters of the company, then it can prove more beneficial. The ratio is calculated by comparing the number of securities or stocks that increase trend to the number of securities or stocks that are in decreasing trend.

It helps determine the upcoming trend in the market, which proves very beneficial for the investors to plan the investment accordingly. It is also useful to determine whether the newly incorporated companies or small companies are performing as per market trends or whether it is beneficial to invest in those companies.

In the above chart, the value of a stock is increasing until day 6, after which it declined for the next three days, and on the 10th day, it gains increased from the previous day. So, here out of 10 days, the number of declining trends is three, and rest seven days, there is an advancing trend. It will be the number of advancing trends divided by the number of declining trends, i.e., 7/3 or 2.33. It shows that the stock is overbought. Since the ratio is greater than two, so it shows that stock is at a higher increasing trend.

### Formula

The Advance-Decline Ratio is calculated by comparing the value of stock or securities increased to the value of stock or securities decreased on the past figures. The figures may be taken for one day to any period it wants to calculate.

Advance-Decline ratio = Number of Advancing Stock / Number of Declining Stocks.

Where,

A number of Several Advancing Stock refers to a number of stock or securities that are in increasing trend like the value of which has been increased. The number of declining stocks refers to the number of stocks or securities that are in decreasing trend, i.e., the value of which has been decreased compared to the previous value.

• It is calculated by dividing the value of shares in an increasing trend to the value of shares in decreasing trend; it determines whether the particular stock is growing or declining in the industry. It is compared with the stock of the company in which the investor wants to invest.
• If the ratio is equal to or less than one, then the stock is said to be a stable or declining trend.
• If the ratio is greater than one, then the stock is at the increasing trend.
• If the ratio is greater than two, then the stock is at a higher increasing trend.
• Traders can estimate the market based on results or value that arrived from the above formula.

### How does it Work?

The investor compares the advance-decline ratio with the market trends and the trends of the company in which he wanted to invest in determining whether his investment will be fruitful or not or to determine whether to buy or sell the security. The ratio determines the upcoming market trend and which helps the investor in utilizing the investment to earn the maximum profit. It can be calculated for any period.

### Examples

#### Example #1

From the latest market trends of the given stocks determine the Advance-Decline Ratio

Solution:

Advance-Decline ratio = Number of Advancing Stock / Number of Declining Stock

• = 5 / 3
• = 1.6667

The market is said to be on an increasing trend.

#### Example #2

The market value of single stocks for the last ten days is given below to calculate.

Advance-Decline ratio = Number of Advancing Trend / Number of Declining Trend

• = 7/3
• = 2.33

Thus, this is greater than two, showing that stock is at a higher increasing trend.

For eg:

1. Ratio Calculated on a Trend Basis: In calculating the advance-decline ratio on-trend basis, the value of the stock of the past few days is compared if the overall result from most of the days shows the increasing trend, then it is said that the market is at the increasing trend and positive results from the investment are expected. For example, the stock shows the increasing trend seven days out of 10 days; then, the stock is on the increasing trend.
2. By the Results of Advance-Decline Ratio: If the result or value of the advance-decline ratio is greater than one, then the market is said to be at increasing; if the ratio is lower than one, then the market is said to be a decreasing trend.

1. Beneficial for Investors: This helps the investors to plan the investment in a way to earn the optimum profits.
2. Determines the Upcoming Trend of Market: This helps determine whether the stock is overbought or oversold. Hence, it helps the Investor and potential Investor to decide whether to buy or sell.
3. Direction for Investment in Small Companies and Start-Ups: The advance-decline ratio of a stock is compared with the projected ratio of start-ups to determine whether start-ups will make a profit in the long run.
4. The base for New and Loss-Making Companies: It helps the new companies, small companies, and loss-making companies to perform better to cope up with the market trends.
5. It protects the investor from wrongful decisions.
6. It is one of the powerful tools if combined with other trends.
7. It can be calculated for any period.

### Conclusion

The Advance-decline ratio is calculated based on technical analysis. It is beneficial for investors to decide whether to invest in the company or not. It determines the future market trend based on current market trends. It is calculated by a formula, which is the number of stocks increasing in value divided by the number of stocks decreasing in value.
