not sure if this holds any truth...
"Finally, the All Ordinaries Index is now 20 points above theS&P/ASX 200 Index, the largest gap in more than seven years, according to CommSec, and at a premium for the first time since January 2005.
In mid-April, the S&P/ASX 200 Index was 22 points above the broader index, now it is 20 points below it. Historically, when the All Ords has moved into a premium against the S&P/ASX 200, it puts an end to any rally."
has anyone heard of this before?
