Avoiding The Recency Bias in Foreign Stock Markets

“International diversification might not protect you from terrible days, months, or even years, but over longer horizons (which should be more important to investors) where underlying economic growth matters more to returns than short-lived panics, it protects you quite well.” – Cliff Asness

The Difference Between an Investment Firm and a Marketing Firm

I’m doing some research for a side project and came across an absolute gem from Jason Zweig that appeared in John Bogle’s book Common Sense on Mutual Funds.

Back-Testing The Tony Robbins All-Weather Portfolio

Tony Robbins has a new book out this week called MONEY Master the Game: 7 Simple Steps to Financial Freedom.
