SEC no longer brain-dead?
Since I slammed the SEC’s incompetence, it’s only fair that I praise their (belated) recent initiative that is (finally) uncovering large insider-trading schemes. I have no idea why they didn’t begin this till two years ago, but at least they’re doing it now:
The case against Rajaratnam, built on recorded conversations within a web of alleged conspirators, offers a glimpse of how U.S. investigators are using more aggressive tactics to identify illegal trades hidden within a blizzard of hedge-fund investments. Additional probes stem from a secret Securities and Exchange Commission data-mining project set up to pinpoint clusters of people who make similar well-timed stock investments…
[T]he SEC began using computer software about two years ago to sift hundreds of millions of electronic trading records, known as blue sheets, attached to the stock exchange reports about suspicious incidents, according to people familiar with the project. By looking for patterns in the library of data, they identified groups of traders who repeatedly made similar well-timed bets.
Once investigators find a cluster of correlated trades, they tap other sources of information to unravel how its members obtain and share tips, the people said. For example, if a group profits on trades before a series of corporate takeovers, the SEC may check so-called league tables listing which investment banks or law firms advised the deals. If one firm was involved in all of them, an employee there may be the source of the leak.
The data-mining strategy yielded one of its first cases in February, when the SEC and U.S. prosecutors charged takeover advisers at UBS AG and Blackstone Group LP with taking part in an $8 million insider-trading case, people familiar with the inquiry said. Authorities used a “novel” technique to detect the scheme, the SEC’s lead investigator on the case, Daniel Hawke, said at the time, without elaborating.
While the investigation of Rajaratnam didn’t stem from the data-mining project, it did start with the SEC’s identification of suspicious trades.
