> A slight over simplification, for example s&p was negative 1% per year from Jan 2000 to Dec 2009. Plus the cost of your leverage. For the 2000s, a US-only investor would only have been saved from the S&P500 by having at least 20% bonds and rebalancing: * [LINK] Of course if you were not US-only, but rather internationally diversified (and rebalanced), you would also have been fine.

Further taking that (e.g.) 80% equities and putting and putting some in ex-JP/in-US would have further helped. Even for US investors the data/research suggests some international exposure leads to better results: * [this video] Further, it looks like even in the US it hasn't been "the US market" that has done well, but rather tech specifically: > Looking at this data, there are two distinct period

> Index funds won't necessarily save you. So first off, picking individual winning stocks is hard because new information that determines pricing comes in randomly, so good luck getting information edge on your counter-party: * [LINK] Further, <5% of stocks actually make up the vast majority of earnings: * [LINK] * [LINK] * [LINK] Those winning stocks also change over time: what used to be a winning choice can become a losing choice, so it's not like you can really set and forget things. So index funds, buying all companies (especially if you go for more total market, like US Russell 3000), allow you to sidestep all of these risks. You are basically buying companies that service the entire e
