US Federal investigators are gearing up to file charges against a wider array of insider-trading networks, some linked to the criminal case against billionaire hedge-fund manager Raj Rajaratnam that shook Wall Street last week, people familiar with the matter said.
The pending crackdown, based on at least two years of investigation, targets securities professionals including hedge-fund managers, lawyers and other Wall Street players, the people said, declining to be identified because the cases aren’t public.
Some probes, like the one that focused on Rajaratnam, rely on wiretaps. Others 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.
Investigators have struggled for years to build cases against large institutional investors such as hedge fund managers, who often deflect regulatory queries about suspiciously timed bets, arguing they’re statistical flukes amid their millions of trades. The case against Rajaratnam, built on recorded conversations within a web of alleged conspirators, offers a glimpse of how US investigators are using more aggressive tactics to cut through the blizzard of trading and trace the flow of information.
“If you’re going to shoot the king, you better shoot to kill,” said Bradley Bennett, a partner at Baker Botts in Washington who formerly focused on insider-trading cases as an SEC investigator. “If they’re going to take on a billionaire, they need to have the strongest possible cases. The defendant’s own words are the strongest possible evidence.”
Rajaratnam, who founded the Galleon Group hedge fund in 1997, was arrested with five alleged conspirators on Friday in what prosecutors called the biggest insider-trading ring targeting a hedge fund. Prosecutors said he and his firm reaped as much as US$18 million by investing on tips from a hedge fund, a credit-rating firm and employees within companies including Intel Capital, McKinsey & Co and IBM Corp.
He hasn’t yet entered a plea. Rajaratnam’s lawyer, Jim Walden, said last week that prosecutors are misconstruing the evidence against his client and that the case isn’t as strong as prosecutors allege.
US senators including Pennsylvania Democrat Arlen Specter have pressed regulators for years to more aggressively scrutinize hedge funds. Some of those concerns were spurred by the SEC’s decision in 2006 to close an insider-trading probe of Pequot Capital Management Inc, once the world’s biggest hedge- fund manager, after investigators said they lacked evidence to bring the case.
The SEC later reopened part of the inquiry focusing on whether Pequot abused information from a former Microsoft Corp employee. In August, Pequot and founder Arthur Samberg, 68, said they may be sued by the agency. Insider-trading claims would be “without merit,” they said.
Many cases begin when stock exchanges send the SEC reports on traders who place profitable bets shortly before corporate announcements. Someone who rarely trades may have difficulty explaining later what prompted an uncharacteristic investment. Hedge funds, on the other hand, can more plausibly attribute their windfalls to skill or chance.
To overcome that hurdle, the 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 US prosecutors charged takeover advisers at UBS AG and Blackstone Group LP with taking part in an US$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, people with knowledge of the case said.
Investigators developed at least one informant in the ring, who began meeting in November 2007 with agents from the FBI, charging documents said. Prosecutors also obtained warrants for wiretaps, a level of surveillance typically reserved for organized crime, drug syndicates and terrorism prosecutions.
Surveillance during the probe of Rajaratnam, 52, led investigators to other suspects and more charges are likely, people familiar with the matter said. US Attorney Preet Bharara said on Friday that the US Justice Department would continue using wiretaps to root out insider-trading.
MORE VISITORS: The Tourism Administration said that it is seeing positive prospects in its efforts to expand the tourism market in North America and Europe Taiwan has been ranked as the cheapest place in the world to travel to this year, based on a list recommended by NerdWallet. The San Francisco-based personal finance company said that Taiwan topped the list of 16 nations it chose for budget travelers because US tourists do not need visas and travelers can easily have a good meal for less than US$10. A bus ride in Taipei costs just under US$0.50, while subway rides start at US$0.60, the firm said, adding that public transportation in Taiwan is easy to navigate. The firm also called Taiwan a “food lover’s paradise,” citing inexpensive breakfast stalls
TRADE: A mandatory declaration of origin for manufactured goods bound for the US is to take effect on May 7 to block China from exploiting Taiwan’s trade channels All products manufactured in Taiwan and exported to the US must include a signed declaration of origin starting on May 7, the Bureau of Foreign Trade announced yesterday. US President Donald Trump on April 2 imposed a 32 percent tariff on imports from Taiwan, but one week later announced a 90-day pause on its implementation. However, a universal 10 percent tariff was immediately applied to most imports from around the world. On April 12, the Trump administration further exempted computers, smartphones and semiconductors from the new tariffs. In response, President William Lai’s (賴清德) administration has introduced a series of countermeasures to support affected
CROSS-STRAIT: The vast majority of Taiwanese support maintaining the ‘status quo,’ while concern is rising about Beijing’s influence operations More than eight out of 10 Taiwanese reject Beijing’s “one country, two systems” framework for cross-strait relations, according to a survey released by the Mainland Affairs Council (MAC) on Thursday. The MAC’s latest quarterly survey found that 84.4 percent of respondents opposed Beijing’s “one country, two systems” formula for handling cross-strait relations — a figure consistent with past polling. Over the past three years, opposition to the framework has remained high, ranging from a low of 83.6 percent in April 2023 to a peak of 89.6 percent in April last year. In the most recent poll, 82.5 percent also rejected China’s
PLUGGING HOLES: The amendments would bring the legislation in line with systems found in other countries such as Japan and the US, Legislator Chen Kuan-ting said Democratic Progressive Party (DPP) Legislator Chen Kuan-ting (陳冠廷) has proposed amending national security legislation amid a spate of espionage cases. Potential gaps in security vetting procedures for personnel with access to sensitive information prompted him to propose the amendments, which would introduce changes to Article 14 of the Classified National Security Information Protection Act (國家機密保護法), Chen said yesterday. The proposal, which aims to enhance interagency vetting procedures and reduce the risk of classified information leaks, would establish a comprehensive security clearance system in Taiwan, he said. The amendment would require character and loyalty checks for civil servants and intelligence personnel prior to
