In the command line interface to my program, the user can create a basket of stocks, etfs, or futures by saying:

basket = stocks

basket = etfs
basket = futures
basket = options

But I want to make a pre-combined basket, consisting of stocks, etfs and futures. Yes, I could make the user enter:

basket = stocks,etfs,futures

But is there a single word appropriate for this predefined basket? "Securities" doesn't include etfs and futures.

Is there an appropriate word?

    $\begingroup$ futes are not securities because regulated by CFTC, but ETF's are securities and regulated by SEC $\endgroup$

    $\begingroup$ Agree with @AlexC. "delta one" is the name that traders will use most of the time. $\endgroup$

These are 'delta one' products, referring to the greek, i.e. a 1-to-1 change in the product's price given a change in the underlying.


I would call these "constituents".
