Did you hear the one about the stock promoter, the lawyer, three figurehead CEOs and seven auditing firm partners?

No, it isn’t a “walks into a bar” joke. It’s a case brought by the Securities and Exchange Commission last month against the players in a sham stock offering. The agency went after all the people involved in what it called “a massive scheme to create public shell companies through false registration statements.”

No big deal, right? The SEC is supposed to be going after bad guys, making them pay fines and lose privileges. But it tends to do a lot better in cases against no-name boiler room types like the ones in the January case than it does with players at powerful banks.

In my column for TheStreet this week, I discussed the contrast in enforcement results between cases against small players and cases against Wall Street’s elite.

In December, for example, the Financial Industry Regulatory Authority, or Finra, brought cases against ten household name firms for flouting the rules that govern research analysts when their firms are pitching for initial public offering business. In its complaints against the firms, Finra described the actions of specific people who broke specific rules. But we never learned their names. Indeed they weren’t charged at all.  You can read my column here.
