I need to find out what the Japanese Nikkei stock index or Hong Kong's
Hang Seng stock index was during the Southeastern Asia's crisis in
1997 - 1998; I need at least 7 - 8 numbers during different days so
that I can make a chart showing the fluctuation for a school
presentation. Any time period will do - beginning of the crisis, end
of the crisis, recovery from the crisis.
Any other Southeastern Asia's stock index will do as well (South Korea
composite index, Stock index of Thailand, etc.)

Hello.

The "Asian Flu" is considered to have begun with the flotation of the
Thai baht in July 1997.

Let's say, for example, that you want ten straight monthly closing
values for the Nikkei starting with July 1997, here they are:

July 1997: 20,331.00
Aug. 1997: 18,229.00
Sept. 1997: 17,888.00
Oct. 1997: 16,459.00
Nov. 1997: 16,633.00
Dec. 1997: 15,259.00
Jan. 1998: 16,628.00
Feb. 1998: 16,832.00
Mar. 1998: 16,527.00
Apr. 1998: 15,641.26

most recent date.

If you want values for other dates, they're very easy to get.
I selected monthly values July 1, 1997 - Dec 31 1998, but you can
change the dates and also switch it to daily or weekly values).

Here are links for the Hang Seng, Thai and South Korean indexes (all
