It would be an interesting exercise to calculate the total value
of shares/contracts traded in the global multiverse in order to
gain exposure to the S&P500 index.
To buy the S&P500, you can:
- go long SPY, SSO, UPRO or a few other less liquid ETFs
- go short SH, SDS, SPXU or a few other less liquid inverse
ETFs
- go long the e-mini ES futures contract or the original larger
SP futures contract
- trade options
- here in the UK, you can gain exposure to
the S&P500 via a Pound Sterling denominated ETF which trades
during London Stock Exchange hours - how? I emailed iShares to find
out: "...using proprietary pricing models that utilise futures,
ADRs and proxy pricing information to indicate underlying price (as
markets would be trading at different times)."
In short, millions and millions of
shares/contracts worth billions and billions - surely BPT
membership represents the merest wrinkle in the space-time
continuum? Ultimately, I have no idea!
There are also similar etfs which aren't exactly the spy, but
mid-cap, etc. that are similar if one is worried about all the spy
activity. In fact, I may do some of that (at my own risk, of
course)...
It would be an interesting
Test signal??

use this tool to find correlated ETFs to SPY

this is a neat little tool that I use to find ETFs that correlate with the SPY
