Common Sense Investing - John Bogle

Foreword:
Investing is all about common sense. Owning a diversified portfolio of stocks and holding it for the long term is a winner's game. Trying to beat the stock market is theoretically a zero-sum game (for every winner, there must be a loser), and after the substantial costs of investing are deducted, it becomes a loser's game.

Common sense tells us, and history confirms, that the simplest and most efficient investment strategy is to buy and hold all of the nation's publicly held businesses at very low cost. The classic index fund that owns this market portfolio is the only investment that guarantees you with your fair share of stock market returns.

Quotes:
"Most investors, both institutional and individual, will find that the best way to own common stocks is through an index fund that charges minimal fees." Warren Buffett

"A low-cost index fund is the most sensible equity investment for the great majority of investors. My mentor, Ben Graham, took this position many years ago, and everything I have seen since convinces me of its truth." Warren Buffett
