This is an easy-to-read primer for ETF investing, focusing primarily on the main reasons why ETFs are the best long-term investment vehicles for most investors. While every day the media bombards us with a dizzying array of market news and stock-picking advice, it turns out the simplest, buy-and-hold, diversification method of investment is still the most painless and effective one for most people preparing for their retirements decades later. For that, ETFs have been increasingly popular for their much lower costs, high liquidity, and ease of portfolio diversification. The book also comes with a very handy appendix explaining how to open one's brokerage account and start investing in ETFs.
