I'm something like 85% cash, munis and treasuries.
Brazil just announced industrial output slowed dramatically, the U.S. 2 year treasury is at 5%, the Yen is gaining on the dollar and the euro, and Bernanke specifically warned of investor complacency and still troubling inflationary 'resource utilization rates' today.
In the interim, the SSEC is down 5.8% as I type this, even market bulls acknowledge the U.S. economy is 'flirting' with recession, and both the BOJ and ECB will be raising rates.
This is not an ideal time to be exposed aggressively to equities, and if you are, you'd be wise to swallow the cost of put insurance, IMO, after the stellar run we've enjoyed since June of last year (a run that a 24 month period would be proud to own in historically normative terms).
