What changed today was the pro QE, low interest rate Yellen nomination!
For me it was the article in the New York Times which came
out last night or at 12.30pm AEDT
I guess for others it was some kind of technical analysis
or our looming quarterly which made the market react at exactly that time of day!
AGO is still a risky play right now, I just notice RIO getting smashed again in New York.
Good Luck tomorrow!
