A collection of the insights Warren Buffett offered in his annual letter Saturday

Billionaire Warren Buffett is known as one of the world's greatest investors, and the 93-year-old has a devout following of people who admire his track record and appreciate his sage advice on life and investing.

On investing in stocks:

“I can’t remember a period since March 11, 1942 – the date of my first stock purchase – that I have not had a majority of my net worth in equities, U.S.-based equities. And so far, so good. The Dow Jones Industrial Average fell below 100 on that fateful day in 1942 when I ‘pulled the trigger.’ I was down about $5 by the time school was out. Soon, things turned around and now that index hovers around 38,000. America has been a terrific country for investors. All they have needed to do is sit quietly, listening to no one.”
