Taming the Bull and the Bear in me!

Read? Many faces of Bull and Bear

Read? Measure, Measure, Measure - Part 2

To tame the Bull and the Bear in me, I watch CAGR of my portfolio very closely as the value of CAGR is influenced by two factors:

1. Holding period: Doing nothing and staying cash over a prolong period is not acceptable and counter-productive. (Too Bearish!)
2. Protecting against losses so position sizing to minimize losses is even more important. (Too Bullish!)
