1. Business Report - Enter senators, and returns go sky-high
Nov 2005snip...
That is an impressive performance, as fund managers are thought to have the Midas touch if they regularly outperform by about 3 percent, and even hedge funds - which charge steep fees for performance - are now on average only 6 percent better than the market.
The academics who conducted the study looked at 6 000 stock transactions made by senators between 1993 and 1998. They noted that the senators did an especially good job of picking up stocks at just the right time - their buys were typically flat before they bought them, but beat the market by 30 percent, on average, in the year after.
However, it seems the senators might have been given a helping hand. Alan Ziobrowski, a professor at Georgia State University, and his colleagues concluded that at least some senators must have been trading "based on information that is unavailable to the public".

Are senators really that smart? The authors of the study suggest a more likely explanation: at least some senators must have been trading “based on information that is unavailable to the public”—in other words, they were engaged in some form of insider trading. It’s impossible to pin down exactly how it happened, but it’s easy to imagine senators getting occasional stock tips from corporate supplicants, and their own work in Congress often deals with confidential matters that have a direct impact on particular companies.

Feb 2004snip...
"The results clearly support the notion that members of the Senate trade with a substantial informational advantage over ordinary investors," says the author of the report, Professor Alan Ziobrowski of the Robinson College of Business at Georgia State University.
He admits to being "very surprised" by his findings, which were based on 6,000 financial disclosure filings and are due to be published in the Journal of Financial and Quantitative Analysis.
"The results suggest that senators knew when to buy their common stocks and when to sell."
First-time Senators did especially well, with their stocks outperforming by 20 per cent a year on average - a result that very few professional fund managers would be able to achieve.
