FACTBOX- Record misery for some in October

LONDON (Reuters) - October has been a month of records on financial markets, many of them unwelcome. Here are a few of them:

STOCK MARKETS

-- MSCI's all-country world stock index .MIWD00000PUS was down 19.9 percent for the month. It was the largest monthly fall in the benchmark's 20-year history in its current form.

-- Despite losses on Friday, however, the index was up more than 11 percent for the week of October 27 to 31, scoring the best performance in the 20 years.

-- MSCI's emerging market index .MSICEF, down around 28 percent in October, was having its worst month since August 1998, during the Russian debt crisis.

-- October also saw the worst monthly performance ever for Japan's Nikkei average .N225. The pan-European FTSEurofirst 300 .FTEU3 fell 12.7 percent on the month, its biggest monthly fall since September 2002. The U.S. S&P 500 .SPX posted its worst monthly performance since the October 1987 Wall Street crash.

-- The VIX index .VIX, which measures volatility on the S&P 500 through options, hit its highest level since at least 1990 during the month.

CURRENCIES

-- The dollar index .DXY, which tracks the greenback against a basket of major currencies, had its strongest month since March 1991, up nearly 8 percent.
