As a work around for streaming & calculating 500 symbols, you should
note that the SP500 is a capitalization weighted index. In practical
terms only about 50 symbols account for most of the weight of the
index. So to achieve a good approximation of the index value, you
would only need to form a composite of these few symbols.
