i think the index quotes are always 15 minutes (or so) stale. To get the current DJIA, multiply the DIA's by 100, and to get the current SPX, multiply the SPY's by 10.
If that is correct, we should see the DJIA down 323 in about 15 minutes, because that's where the DIA's are right now...
Hard work often pays off over time,
but laziness always pays off right now.
