Just wondering how the point value is calculated for an index. I read that
The ASX 200 is market-capitalization weighted meaning that a company's contribution to the index is relative to its total market value i.e. share price x number of tradeable shares.
Yes thanks for that. So a futures contract index point value is determined by other futures contract buyers and sellers. Who are in turn driven to buy orsell contracts in reaction to the underlying index movement.
What I meant was the cash market index contracts that CFD providers have. They use the XJO as the index and it is point for point but the contracts are tradeable off that index movement.
No worries. I'll do research on the differences between cash market and futures market.
Futures vs Cash Market
It is important to distinguish cash market from futures markets when looking at a particular commodity. Many people do not realize that there is a difference between the two.
So in the wash up, contracts don't move the XJO. The trading of the stock that make up the index moves the XJO. The derivatives markets of this index are then sold or bought via contracts exchanged with one another. For example the SFE SPI.
