ETFs wrap up rebalancing period in exciting 15 minute ATC finale. Activity on the last official day of ETF balancing, totally overshadowed GDP data in HCMC, which by the way, came in at 7.9% for the 1H (down from 8.1% in 1H12). Trading proved to be quite exciting as the market swung from an intraday low of 495 to break 500 only to be pushed back down again in the ATC session by massive selling pressure that was equally matched by demand from bargain hunters.
