The investment philosophy at Berkshire Hathaway is well known: Buy great businesses that are run by great people and keep them 'forever'. However, I believe Buffett/Munger have said that 'Buy and Hold Forever' may not be the best method for people with smaller amounts of capital.
So, the question is: What methods have they recommended for small investors?
