Input: If you have a pulse and own a stock  you probably have seen  Peter Tuchmanâs  face. But a household name  he  ainât.
 Tuchman âs histrionics play out on the stage of the New York Stock Exchange  where the 60-year-old trader â âIâve been 55 for five yearsâ â is known as the most photographed person at the NYSE.
 Tuchman  is the money setâs Rorschach test.  His  facial expressions mirror the aspirations and disappointments of investors the world over: Anguish. Anticipation. Desperation. Triumph.
You can spot  him  on CNBC roaming around in the background  the white-haired  blue-jacketed trader  personal computer in hand.  He  is all over the Internet and news sites as the background prop to a thousand stock market stories.
 Tuchman  got  his  volatility fix this past week. The Dow Jones industrial average bounced like flubber over six sessions  tossing around trillions of dollars in wealth. We talked to  him  by phone while  he  patrolled the floor of the NYSE. The conversation was edited for length and clarity.
