wolf of Wall Street

Not for nothing had Regan been named by his associates the Wolf of Wall Street. While usually no more than a conservative, large-scale player, every so often, like a periodical drinker, he had to go on a rampage of wild enduring stock-gambling. At least five times in his long career he had knocked the bottom out of the market or lifted the roof off, and each time to the tune of a personal gain of millions.]

He [Ernest Whitworth Marland] always felt that he had been euchred out of control of his Marland Oil Co. by unscrupulous financiers and when in 1932 he was elected to Congress, he kept up a steady racket against "the wolves of Wall Street."
