<<When the index was first published on Feb. 5, 1971, its base value was 100. An index of 2,000 indicates that the total market value of stocks in the index is 20 times greater than it was back then. The base value is adjusted when stocks are added to or subtracted from the index.>>

If this is true, then the absolute value of the index seems kind of meaningless. Without knowing the base value, the absolute value doesn't seem to say a lot. Right now, the absolute value of the index is ~1750 or so. At one point in 2000, the index was ~5000. At first guess, that seems to say that the the index has dropped two thirds of its value. However, if the base value is twice as high as it was then, then the index has really dropped five-sixths of its value (a loss of 84% compared to a loss of 66%).

I will look to see if I can find info on the changes to the base value.
