Can volatility predict returns?
The level of volatility tends to persist over time, and, hence, we expect that past volatility should provide some indication of future stock market returns. Several studies, however, have found that volatility, by itself, explains little of the variation of stock market returns.
What is volatility prediction?
A volatility model should be able to forecast volatility. Virtually all the financial uses of volatility models entail forecasting aspects of future returns. Typically a volatility model is used to forecast the absolute magnitude of returns, but it may also be used to predict quantiles or, in fact, the entire density.
How do traders predict volatility?
Standard deviation is the most common way to measure market volatility, and traders can use Bollinger Bands to analyze standard deviation. Maximum drawdown is another way to measure stock price volatility, and it is used by speculators, asset allocators, and growth investors to limit their losses.
How do you use volatility to predict price?
First, divide the number of days until the stock price forecast by 365, and then find the square root of that number. Then, multiply the square root with the implied volatility percentage and the current stock price. The result is the change in price.
Can implied volatility predict returns on the currency carry trade?
Currency carry strategies have long positions in currencies with a high interest rate and short positions in currencies with a low interest rate. Hence, our findings cast doubt on implied volatility as a stand-alone timing indicator for currency carry trading in real-life portfolio decisions.
What is a good volatility model?
A volatility model must be able to forecast volatility. A good volatility model must be able to capture and reflect these stylized facts. To illustrate these stylized facts, data on the Dow Jones Industrial Index were used, and the ability of GARCH-type models was used to capture these features.
What does volatility mean in stocks?
Volatility is the rate at which the price of a stock increases or decreases over a particular period. Higher stock price volatility often means higher risk and helps an investor to estimate the fluctuations that may happen in the future.
How is intraday volatility measured?

How to predict the volatility of a data set?
One way which I used here is, First will predict the volatility using all the columns in the data we have and then will find the important feature and use only that to predict the volatility and measure the performance using Mean Absolute Error (MAE).
How accurate is the spy volatility prediction?
A pleasant surprise: the agreement is 58\% of the days. If this were the accuracy for predicting the sign of the SPY return itself, we should prepare to retire in luxury. Volatility is easier to predict than signed returns, as every finance student has also been taught. But what good is a good volatility prediction?
Is realized volatility prediction useful for implied volatility prediction?

How accurate is volatility targeting?
Most market variables remain largely unpredictable, but volatility has certain characteristics that can increase the accuracy of its forecasted values. The statistical nature of volatility is one of the main catalysts behind the emergence of volatility targeting and risk parity strategies.
