It's Friday, November 22nd, 1963 at the New York Stock Exchange over a month before Warren Buffett eyes American Express stock.

The vice chairman of the exchange Walter Frank rubs his eyes and looks down on the trading floor from his office.

Walter is worn out. Over the past few days Wall Street has been hit hard by the great salad oil swindle.

The long respected investment firm Halpton Company has been suspended from trading.

American Express stock is plummeted and creditors are banging on their door due to their connection to the scandal.

The Dow has dropped 1.3% over the last 24 hours. Walter tries to stay positive as he watches the action on the floor, but he fears the market is in for another bad day.

But then there's a commotion. A young clerk runs out onto the trading floor shouting something.

Walter can't make out what, but he doesn't think much of it shouting clerks are par for the course at the stock exchange.

But then Walter hears screams and whaling.

Very shortly after Ed Gray, the executive vice president of the New York Stock Exchange rushes into Walter's office.

Walter, they shot Kennedy.

What? The president, he's been shot in Dallas. Is he alive? We don't know.

Walter looks out over the floor and his heart starts to pound in his chest.

The news about president Kennedy has immediately resulted in a massive sell-off.

Walter watches his stock prices tick down on the big boards at each end of the trading floor.

He takes a deep breath and tries to collect himself.

Oh God, Ed, the market is going to collapse when we don't do something fast.

We need to get the chairman and the president together if we want to do anything.

Now they're both out today. Where are they? I don't know and we don't have time to figure it out.

Walter can hear the shouts of sell, sell coming from the trading floor.
