JACK BOGLE: 'Just buy the damn index fund'

The letter, which is set for release at the end of February, will mark the 50th edition of Berkshire Hathaway's annual letter, and will include reflections from Buffett and his right-hand man Charlie Munger on the last 50 years as well as the next 50. 

Included in the FT's profile are comments from fellow investing legends including Cliff Asness, Wells Fargo's John Stumpf, and the grandfather of indexing: Jack Bogle.

Bogle, who is never one to hold back his thoughts on the merits of passive indexing, says of Buffett's success and the efforts for future investors to replicate this success:

"Beethoven could tell you how to write a symphony but you can't write a symphony like Beethoven does. You can't copy, with any hope of success, a Beethoven or Buffett. You can copy Bogle at any moment of time. Just buy the damn index fund."
