I wanted to show you all a recent blog post from Barry Ritholtz. Barry is the co-founder and chief investment officer of Ritholtz Wealth Management. He is a profoundly sane and reasonable money manager, a trusted financial journalist and blogger, and respected financial expert. He also manages to explain modern investing and business in understandable terms.
I don't agree with everything he says here (I do love to pick stocks and have more of my assets in those individual businesses than I do in ETFs— but that's not the best strategy for most folks), but I do agree with the following: Behavioral management may be the single most important aspect of successful investing. No matter what assets you hold, if you can avoid selling in a panic each time you see your holdings drop beyond a comfortable level, you'll likely be okay over time.
a link to his post is here, and I've reprinted the text below.
