This is a great article with some great advice for any investor, but especially for those just beginning.

“If you’re going to come to the poker table, you’re going to have to beat me. … We have 1500 people who work at Bridgewater. We spend hundreds of millions of dollars on research and so on, we’ve been doing this for 37 years.”

“The nature of investing is that a very small percentage of the people take money, essentially, in that poker game, away from other people who don’t know when prices go up whether that means it’s a good investment or if it’s a more expensive investment. Too many investors are reactive decision-makers. If something has gone up, they say, ‘Ah, that’s a good investment.’ They don’t say, ‘That’s more expensive.'”

“The biggest mistake investors make is to believe that what happened in the recent past is likely to persist. They assume that something that was a good investment in the recent past is still a good investment. Typically, high past returns simply imply that an asset has become more expensive and is a poorer, not better, investment.”

After reading it, I wonder if I'm too heavily invested in stocks.
