Vancouver Stock Exchange
From Wikipedia, the free encyclopedia

The Vancouver Stock Exchange (VSE) was a stock exchange based in Vancouver, British Columbia. It was the third major stock exchange in Canada, after the Toronto Stock Exchange (TSX) and Montreal Stock Exchange (MSE), and featured many small-cap and exploration stocks.

In 1991, it listed some 2,300 stocks. Some local figures[citation needed] stated that the majority of these stocks were either total failures or frauds. A 1994 report by James Matkin (Vancouver Stock Exchange & Securities Regulation Commission) made reference to "shams, swindles and market manipulations" within the VSE[1]. Regardless of the low opinion several held it in, it had roughly four billion dollars in annual trading in 1991.[2]

On November 29, 1999 the VSE was merged into the Canadian Venture Exchange (CDNX), along with the Alberta Stock Exchange (ASE) and the minor-cap stocks from the Bourse de Montréal (MSE). The trading floor of the old VSE remained as the trading floor of the new CDNX.

The history of the exchange's index provides a standard case example of large errors arising from seemingly innocuous floating point calculations. In January 1982 the index was initialized at 1000 and subsequently updated and truncated to three decimal places on each trade. This was done about 3000 times a day. The accumulated truncations led to an erroneous loss of around 25 points per month. Over the weekend of November 25-28 1983, the error was corrected, raising the value of the index from its Friday closing figure of 524.811 to 1098.892 [3][4].
