Dynamic Volume-Volatility Relation ... intuition and their model thus suggests that price changes accompanied by high volume will tend to be reversed, this will be less true of price changes on days with low volume. Using very bad shorthand, d1 and d2 are inputs into N(), and N() can be expressed as the probability of the expected value or the most probable value which in this case is the discounted expected stock price at expiration.d1 has two σs which is volatility in the numerator and one in the denominator. Granger causality test was used to determine the direction of relationship between price and volume. In addition, various other measures of volatility based on volume, price range have been proposed in the literature. It has earnings next month. 20, Issue. generalize our model, rather than just focusing on learning one stock. After controlling for oil market factors (trading volume, price returns, and liquidity), we discover that a one standard deviation increase in COVID-19 cases (which is 2,578) and deaths (which is 157) results in an in-crease in daily oil price volatility by between 8.6% and 22%.

Also, their model implies that groups with greater disagreement will have a more pronounced relationshi p between volatility and volume. Using a tool like Bollinger Bands® to forecast future price ranges is a time-honored technique but its calculations are simplified and in some situations flawed. stochastic volatility such as models of stochastic volatility or implied volatility models from option pricing are not at debate here.
