BEIJING (Reuters) - On Monday the index fell a bizarre 64.89 points on the anniversary of the bloody June 4, 1989, crackdown on pro-democracy protesters in Tiananmen Square.

In another twist, the Shanghai Composite Index opened at 2346.98 points on the 23rd anniversary of the killings. The numbers 46.98 are June 4, 1989, backwards.

"Whoa, these figures are too freaky! Very cool!" said a microblogger. "The opening figure and the drop are both too creepy," said another.

The Shanghai Stock Exchange Composite Index is calculated by adding up the market capitalizations of hundreds of stocks and then converting the sum into an index based on a value of 100 on Dec. 19, 1990. Richard W. Kershaw, the managing director for Asia forensic technology at FTI Consulting, a global financial investigations company, said that it would be almost impossible for anyone to coordinate the buying and selling of so many stocks to produce a specific result.

But hackers have targeted the computer systems at other stock exchanges in the past, and Mr. Kershaw said it was at least possible that this might have occurred in China. He predicted that the government would investigate, adding, “You can bet we’ll never hear the results. ”

包括台股在內的全球股市今天重挫，滬股也不例外，收盤比前一天下跌2.73%，換算成點數，恰巧是64.89點。

瞎摸象: 此事關鍵之處在 『重挫』，聽說 2.73% Drop 是少有的！ 因此，人為操弄 (作弊) 的 可能性 極微 !
