題 目：Spot covariance estimation with synchronous high-frequency finance data

摘要Abstract:
Empirical studies have pointed out the importance of considering different temporal variations in correlations between asset prices. Currently, high-frequency profiles sampled asynchronously across different assets have mainly applied for integrated covariance estimation but less so for spot covariance estimation. Based on the seminal works of Malliavin and Mancino [1,2] in conjunction with the principle component analysis approach, in this talk, we try to propose a novel spot covariance estimation with synchronous high-frequency finance data. We will point out which kind of high-frequency data we are interested in and briefly explain why we apply the Malliavin-Mancino method to these data.
