Factor Investing is an investment strategy that involves focusing on specific drivers of return in an attempt to beat the market and maximize returns. It is a style of investing which has experienced a surge in popularity and usually involves two main types of factors, namely macroeconomic factors and style factors. Examples of macroeconomic factors include inflation and real rates whereas style factors may vary from momentum to minimum volatility. Blackrock estimates that Factor-Based Strategies are projected to grow to the value of $3.4 trillion by 2022 from the level of $1.9 trillion at the beginning of the year. Given its popularity and capacity to grow in the coming years, this article will break down the top books, tools, podcasts, and blogs to expand your knowledge of Factor Investing.
Through these resources, you can begin your own Factor Investing portfolios, with pre-made quantitative strategies available on the Aikido Finance website along with rebalancing services available later this year.

Published in 1996, this book provides insights into stock performance going all the way back to 1926. This book succeeds in outlining which investment strategies are winners and which are losers based on historical evidence and in a way that is clear and concise to even beginner investors. Included in this book is the debate between value and growth investing, small vs large-cap stocks, and whether these strategies work outside the United States.
