Machine-translated · View original
A lab that analyzes high-frequency financial data using statistical methods.

AboutAbout the lab
Reading financial data through statistics.
The lab of Assistant Professor Hiromi Misaki, who specializes in statistics, econometrics, and financial econometrics, analyzes financial data such as asset prices using statistical methods.
In particular, it works on methods for estimating the variance and covariance of asset prices from high-frequency data, meaning large volumes of observations recorded at short intervals.
Research keywords include financial risk, time series analysis, and state space models.
Key terms
- High-frequency data
- Data recorded in fine detail at short time intervals, such as stock trading records. In this lab, it is used with financial time series data.
- Volatility
- A measure of how much an asset's price moves.
- Portfolio
- The combination of multiple assets, such as stocks, that one holds together.
ResearchResearch themes
The lab analyzes price data recorded in financial markets using methods from statistics and econometrics. It works on estimating the variance and covariance of asset prices using high-frequency data, and on financial risk management.
*Illustrative imageEstimating Volatility from High-Frequency Data
The lab compares estimators of price volatility (the magnitude of price fluctuations) and covariance computed from high-frequency price data. It examines them through simulations that assume noise contained in transaction records, and with real data from the Japanese stock market.
*Illustrative imageEmpirical Study of Risk Parity Investing
The lab empirically analyzes hierarchical risk parity, one approach to portfolio construction, to test whether it can actually be used in the Japanese market.
