Abstract
In this study, we conduct an analysis of intraday spot volatility using high-frequency data from the SPDR S&P 500 ETF (SPY). We begin with the assumption that the intraday volatility of asset prices exhibits time-variation. To capture this dynamic behavior, we construct proxies for the unobserved spot volatility by applying appropriate estimators to the high-frequency price data. Following the estimation procedure, we employ various forecasting models to generate volatility forecasts. Finally, we evaluate and compare the predictive performance of these models using established forecast evaluation metrics, and analyze the results.
