Upside/Downside Ratio


The Upside/Downside Ratio is a market breadth indicator used in technical analysis. It measures the momentum of stocks showing upward progress (upsides) versus those showing downward progress (downsides). The ratio provides investors with insights into market sentiment, with a ratio greater than 1, indicating bullishness, and a ratio less than 1 suggesting bearishness.


The phonetics of the keyword: Upside/Downside Ratio are:Upside: /ˈʌpˌsaɪd/Downside: /ˈdaʊnˌsaɪd/Ratio: /ˈreɪʃioʊ/

Key Takeaways

  1. The Upside/Downside Ratio is a market breadth indicator that shows the relationship between the volumes of advancing and declining issues on an exchange. It’s often used by traders and analysts to gauge the overall market sentiment.
  2. The ratio is calculated by dividing the volume of advancing issues by the volume of declining issues. A ratio of more than 1 indicates a bullish market sentiment as more stocks are on the upswing, whereas a ratio of less than 1 signifies a bearish market as more stocks are on the downswing.
  3. The Upside/Downside Ratio is often used in conjunction with other market indicators and charts to validate trends and to help forecast future market movements. However, like all indicators, it should not be used in isolation as it can lead to misleading results.


The Upside/Downside Ratio is an important analytical tool in business and finance as it helps investors assess the potential risk and reward associated with a particular investment. It measures the probable gains (upside) against the potential losses (downside). Investors use this ratio to determine the relationship between return and risk, thus helping them make informed investment decisions. If the upside potential outweighs the downside risk, the investment may be considered a good opportunity. Conversely, a high downside risk may deter investors from pursuing an investment. Essentially, the Upside/Downside Ratio enables investors to better anticipate and mitigate risks while maximizing returns, ultimately facilitating more effective investment strategies.


The Upside/Downside Ratio serves an important purpose in finance as it is used to measure the potential gains of an investment against the potential losses. In essence, it assesses the risk versus reward trade-off. It provides valuable insight into the maximum anticipated gain (upside potential) and the maximum potential loss (downside risk) based on historical or statistical data. A greater ratio is often preferred as it would indicate that the potential gains outweigh the losses, thus signaling a good investment prospect.Moreover, the ratio is utilized by investors to make crucial investment decisions and strategic plans. By determining the balance between rewards and risks, investors can align their investments according to their risk tolerance level. For example, conservative investors might gravitate towards securities with a higher upside/downside ratio, which offers protection against potential losses while still providing modest income. On the other hand, more aggressive investors may be comfortable investing in securities with a lower upside/downside ratio in pursuit of high returns. Overall, the ratio serves as an essential tool in constructing and managing an effective investment portfolio.


1. Investment Portfolios: An investor has built a portfolio of varied assets including stocks, bonds, real estate, etc. The Upside/Downside ratio could be used to analyze the performance of this portfolio over a certain period. If the ratio indicates that the portfolio’s return potential (upside) significantly outperforms the risk of loss (downside), this might be a good signal to continue with the current investment strategy. 2. Individual Stocks: Imagine an investor is considering investing in a tech startup. The investor could apply the Upside/Downside ratio to calculate the potential gains versus potential losses of this investment. If the startup’s projected revenue growth (upside) is high and the risk of losing the investment (downside) is relatively low, the investor might opt to buy the stock.3. Mutual Fund Performance: An investment manager might use the Upside/Downside Ratio to compare the performance of different mutual funds. This ratio could highlight which mutual fund has better potential return compared to its investment risk, therefore aiding the investment manager to make sound decisions and manage the fund effectively.

Frequently Asked Questions(FAQ)

What is the Upside/Downside Ratio in finance?

How is the Upside/Downside Ratio calculated?

What does a higher Upside/Downside Ratio indicate?

A higher Upside/Downside Ratio indicates a greater the expected return on investment during upward moving markets compared to the potential losses during down markets. This suggests that the investment has more profit potential than risk.

Is a higher Upside/Downside Ratio always a good indication of an investment?

How frequently should an investor calculate the Upside/Downside Ratio?

The frequency of calculation really depends on an investor’s specific investment strategy. Some may find it helpful to calculate on a quarterly basis, while others may prefer to do it annually. However, one should consider that market conditions can change rapidly and impact the ratio.

Can the Upside/Downside Ratio be used to compare different investments?

What level of expertise do I need to use the Upside/Downside Ratio effectively?

While the mathematical formula for calculating the Upside/Downside Ratio is fairly simple, interpreting the results and applying it to investment decisions requires a good understanding of market dynamics and investment risk assessment. Therefore, it may be more suitable for intermediate and advanced investors.
