I am stunned and saddened by this news.
Traders here on the floor of the New York Mercantile Exchange are in shock.
The NYSE may have been the Mark's home for the many years that he anchored "Squawk on the Street" from that floor, but he also found his way into the hearts of many of the traders here at the Nymex.
He gained tremendous respect among this trading community for his understanding of the markets and his willingness and readiness to hold everyone he questioned accountable for their perspective and positions.
He will be greatly missed.
