Hello!

Today, I will be showcasing an aggregate calendar effect strategy that I created from the results found in my prior two calendar effect posts (Part 1 and Part 2). This strategy outperforms the S&P 500 in terms of total return and risk-adjusted returns (over double the Sharpe ratio of the S&P 500).

In my Recent Academic Research posts, I’ve highlighted multiple papers demonstrating how certain return patterns in the U.S. stock market can be exploited for outperformance. These strategies capitalize on periods of abnormally high or low returns at specific times of the year.

Let’s get into it.
