Stock market floor photos. We’ve all seen them, and we run quite a few of them in the Arizona Daily Star — photos of frantic traders on the New York Stock Exchange floor, variously grinning, gasping, groaning or grimacing depending on whether the market is soaring or plunging.

And lately, that means more grimacing than anything else — and that means you might see trader Peter Tuchman.

Tuchman is a distinguished-looking gent with a mustache and a balding pate giving way to gray tresses not unlike Albert Einstein’s fuzzy coif. He’s been identified in Associated Press photo information as a trader for Maven Securities.

Here’s Peter, rubbing his head in apparent despair in an Associated Press photo we posted yesterday on AzStarBiz with a close-of-markets story about how stocks tanked amid the latest batch of bad economic news:

But I thought I’d seen this face of agony before, so I did a little checking. Turns out, Tuchman is something of a poster boy for Wall Street Despair. It doesn’t hurt that he does a lot of head-rubbing and head-holding.

Here’s a couple of shots of Peter on Thursday, July 26, 2007, when Wall Street suffered its second-biggest plunge of the year at the time:

A few months earlier, on March 13, 2007, here’s Peter coping with a 200-point plunge in the Dow Jones industrial average (this one made ChinaDaily):

I don’t mean to make fun of Mr. Tuchman, he may be a fine trader and he looks like a nice guy. There are a few other news shots of Peter in recent years, simply looking at overhead tote boards and writing up orders.

So I’ll leave you with an image of Peter’s lighter side, as he jokes with actor Brad Garrett (of TV’s “Everybody Loves Raymond” and “Till Death”) on the floor of the New York Stock Exchange prior to ringing the closing bell on Sept. 18. That day, Tuchman had reason to smile: The Dow was up more than 400 points.
