List of largest daily changes in the Dow Jones Industrial Average

This is a list of the largest daily changes in the Dow Jones Industrial Average. [ [http://online.wsj.com/mdc/public/page/2_3047-djia_alltime.html Historical Index Data - WSJ.com: All-Time Largest One Day Gains and Losses] ] [ [http://www.djindexes.com/mdsidx/downloads/xlspages/high_low_lights.xls Highlights/Lowlights of The Dow] (Excel spreadsheet)] It is current as of October 9, 2008.

Largest point changes

Note that the first four tables show only the largest one-day changes between a given day's close and the close of the previous trading day, not the largest changes during the trading day (i.e. intraday changes).

Largest percentage changes

Note that some sources (including the file [http://www.djindexes.com/mdsidx/downloads/xlspages/high_low_lights.xls Highlights/Lowlights of The Dow] on the [http://www.djindexes.com/mdsidx/?event=showaverages Dow Jones website] ) show a loss of -24.39% (from 71.42 to 54.00) on December 12, 1914, placing that day atop the list of largest percentage losses. The New York Stock Exchange reopened that day following a nearly four-and-a-half-month closure since July 30, 1914, and the Dow in fact rose several percent that day (from 71.42 to 74.56, or +4.4%). However, the apparent decline was due to a later 1916 revision of the Dow Jones Industrial Average, which retroactively adjusted the values following the closure but not those before, and it represents the only discontinuity in the index’s history rather than an actual loss.
