I think timeframe is important here.
Rydex is definitely dumb, but also almost assuredly Swing-to-IT traders.
ISEE is options traders and not dealers (at least theoretically, any more), so it would seem likely that they're short-term oriented. And, for what it's worth, there was a steep drop in bullishness yesterday.
AAII is mostly older, longer-term investors. They actually tend to have a somewhat durable, optimistic bias.
Now, the VIX and derivatives, I consider to be "smart money" indicators. The VIX proper is looking a bit mixed on the Swing-IT, and same with the ST. I'm not confident of my read on these because of the sharp and fast shift, which tends to mess with my indicators.
My overall takeaway is that it's unduly risky to short this market, and, more to the point, the price action and the overall indicator behavior strongly suggests (to me, at least) that the entire correction was "inorganic", and what we have been seeing is unwinding of news related trading, untethered from market fundamentals*.

*by "fundamentals", I mean all the things that come together to drive price discovery in the stock market, not necessarily earnings or book values or all the things we have all come to ignore. We use technicals to simply shorthand all those things, rather than try to figure out what all those things may or may not be.
