I've submitted an article for publishing, but in the meanwhile...
"The speed at which stocks have dropped 10% (defined as a correction) two times in a short period of time has happened just three times in the last 100 years. 1927, 2000 and 2008."
Disclosure: I am/we are long XLY, XLK, XLV.
Additional disclosure: but looking to see sector ETFs (on a bounce) so that my only positions will all be bearish positions on the S&P500.
