Upside/Downside Ratio
The volume of advancing NYSE issues divided by the volume of declining NYSE issues.
Investopedia Commentary
If the upside-downside ratio is greater than 1, it shows that there is more volume in stocks that are increasing in price than in stocks that are decreasing in price. The higher the ratio is, the more bullish the market.
