The October 27, 1997, mini-crash is a global stock market crash that was caused by an economic crisis in Asia, the "Asian contagion", or Tom Yum Goong crisis. The point loss that the Dow Jones Industrial Average suffered on this day currently ranks as the 18th biggest percentage loss since the Dow's creation in 1896. This crash is considered a "mini-crash" because the percentage loss was relatively small compared to some other notable crashes. After the crash, the markets still remained positive for 1997, but the "mini-crash" may be considered as the beginning of the end of the 1990s economic boom in the United States and Canada, as both consumer confidence and economic growth were mildly reduced during the winter of 1997–1998, and when both returned to pre-October levels, they began to grow at an even slower pace than before the crash.
A capitalization-weightedindex, also called a market-value-weighted index is a stock market index whose components are weighted according to the total market value of their outstanding shares.

The impact that individual stock's price change has on the index is proportional to the company's overall market value, in a capitalization-weighted index. In other types of indices, different ratios are used.
