Index Investing is a passive investment technique that attempts to generate returns similar to a broad market index. This type of investing involves buying a basket of stocks that represent the market as a whole, and holding them for the long-term. While this strategy doesn't require much active management, it does require patience and discipline.For many investors, indexing is the best way to participate in the stock market without having to pick individual stocks. It's a simple and straightforward approach that can provide you with decent returns over time. And since you're not actively trying to beat the market, it also takes away some of the stress associated with other types of investing.
