Intro to rules based Investing – Why follow an investment strategy?

1. Basics

What is rules based Investing?

In rules-based-investing we define a clear set of rules. These rules comprise an investment strategy. Here is an example strategy:

“At the first day of the month, look at the performance of bonds versus stocks by calulating the 3-month performances of two exchange traded funds, SPY (the SPDR S&P 500 ETF) and TLT (the iShares 20+ Year Treasury Bond ETF).
If SPY outperforms, then re-balance the portfolio to 60% SPY, 40% TLT. If not, rebalance to 40% SPY, 60% TLT.”
