What is the Consumer Price Index(CPI)? The Consumer Price Index (CPI) is a measure of the change in prices paid by consumers for a basket of goods and services. It is one of the most widely followed economic indicators, and it is used by investors to gauge inflation and make investment decisions. How is the CPI calculated? The CPI is calculated by the Bureau of Labor Statistics (BLS). The BLS surveys households across the United States to collect data on the prices they pay for goods and services. This data is then used to create a "basket" of goods and services that represents the spending habits of the average American household. The BLS calculates the CPI by comparing the prices in the basket of goods and services in a given month to the prices in the same basket of goods and services in a base year.

A New Perspective on Value Investing: Periodic Stock Rotation

What is value investing?

Value investing is an investment strategy that involves buying undervalued stocks and waiting for them to appreciate in value before selling. It relies on the ability to find undervalued stocks in the market. Value investing is popular with many investors, although at certain times there is more focus on growth stocks. However, value investing is recognized for its ability to generate long-term investment performance.

A New Perspective on Value Investing: Periodic Stock Rotation


Quantitative value investing

Quantitative value investing is an investment approach that uses statistical and mathematical methods to identify undervalued stocks. It aims to use a scientific and objective approach to make investment decisions.


New perspectives on value investing

However, a new perspective on value investing has emerged: "periodic stock rotation". This perspective argues that value investing is not always about holding on for the long haul, and that periodic portfolio rotation can lead to higher returns than holding undervalued stocks for the long term.


The benefits of periodic stock rotation

Holding on to an undervalued stock for a long period of time can benefit from the market's recognition of the stock. However, the limitation of this approach is that changes in the market may cause the stock to become overvalued or cause other stocks to become more undervalued. In this case, it may be more profitable to buy a new undervalued stock than to hold on to the old one.


Investment lessons

Based on these results, we can draw two investment lessons. The first is that it is risky to be concentrated in a small number of stocks, even if they are value investments. The second is that periodic stock rotation is a quantitative concept worth considering. Periodic stock rotation creates a low-buy-high-sell phenomenon and provides an opportunity to bring cheaper stocks into the portfolio, which can improve returns.


Opportunities for retail investors

This investment strategy is better utilized by retail investors than institutional investors. Institutional investors have a harder time executing these strategies because large amounts of money can increase the volatility of a stock's price with periodic buying and selling. However, retail investors don't have to worry about these issues as much, which makes value investing strategies with periodic stock rotation more effective.
