When reading Japanese financial news, I found that different units were used for different stock indexes. For example, ドル／セント was used for Dow Jones Industrial Average, while ポイント was used for NASDAQ Composite. (Emphasis mine)
Why are different units used to describe the different indexes? Why is Dow described in dollar, and NASDAQ in point?
This is different from English's terminology, where point was used for Dow.
My initial guess is that the weighing method has something to do with the units used. Dow is price-weighed where NASDAQ is market cap-weighed. But I could not work out how this leads to different units being used.
