This is the weekend that Warren Buffett posts his Annual Letter. Each year Warren puts a years worth of thinking into a short, this year 21 pages, letter. Many believe this letter is a mini MBA from an incredible teacher. Warren has a book he credits for much of his success. It's a book written by his mentor and he still uses the philosophy of the book today.
The Intelligent Investor by Benjamin Graham was the book that Warren credits with his success. Below is a video answering why he thinks this book is worth reading.
Warren Buffett knows business and investing. He gives us a free course each year with his Annual Letter and he believes we should be reading The Intelligent Investor. If it's good enough for him, it's good enough for me.
