Ndx index options
There are Weekly Options that expire at the close of every Friday. First of all, there are two types of Options settlement – American style and European style. And there are two baskets of securities when it comes to settlement procedures – 1) Equities and ETFs and 2) Major Indices like the SPX, NDX and the RUT. Index options are calls or puts where the underlying asset is a stock market index i.e the Dow Jones or the S&P 500 index. Using index options enables option traders to bet on the direction or volatility on an entire equity market (or market segment) without having to trade option on all of the individual securities.
