Stock sales by America’s corporate chieftains exceeded purchases last month by the widest margin since 1987, suggesting they do not share the confidence of investors who sent the Standard ＆ Poor’s 500 Index to a six-year high. Executives including Microsoft Corp’s Bill Gates, Google Inc’s Eric Schmidt and Kohl’s Corp’s William Kellogg in aggregate sold US $63.18 of shares for every US $ 1 they bought in November, an analysis by Bloomberg of data from the Washington Service research firm showed. That’s the highest since at least January 1987.
Stocks have rallied even as analysts forecast that a streak of average profit growth above 10 percent for S ＆ P500 companies will end this quarter. The US economy expanded at a 2.2 percent annual rate in the third quarter, down from the 5.6 percent pace in the first quarter.
Cape Canaveral, United States
After a fiery ascent that turned night into day, space shuttle Discovery and its crew headed to the International Space Station yesterday to rewire the orbital outpost.
Astronauts in orbit yesterday inspected the shuttle for potentially critical heat shield damage. Discovery will dock with the space station today, and the intricate work will begin. Three complicated space-walks are planned to rewire the space station from a temporary to a permanent power source. NASA had to beat the odds to get off the launch pad on Saturday in the first night-time launch in four years. After only a 30 percent chance of good weather earlier in the day and a 2-hour delay in fuelling, Discovery streaked through a moonless sky at 0147GMT yesterday.

Hamburg, Germany
Traces of radiation found at two sites in Germany linked to a contact of poisoned former Russian spy Alexander Litvinenko are likely the rare radioactive substance polonium-210, authorities said yesterday. Police said on Saturday that traces of alpha radiation had been found at properties in and near Hamburg used by the ex-wife and former mother-in-law of Dmitry Kovtun.
The Russian businessman met Litvinenko in London on November 1, the day the former spy is believed to have fallen ill. Litvinenko was killed by polonium-210.
Germany’s Federal Office for Radiation Protection said in a statement yesterday that "small traces of radio-active substances were detected, and there is a high degree of probability that this is polonium. "
