BRK-A was 140,900 per share a week ago(oct 3). Now its 107,900 meaning he's lost about 17.9 billion in 1 week. So he is losing about 107 million dollars per hour or 1,780,000 per minute...or break it down one more time to 29k per second. Imagine looking at your IB account and seeing it deplete at 29k every second. So just imagine that ever 7 or 8 seconds, buffet lost enough money to buy an average home.
