Market tests 570 level with caution. Yesterday, we noted that the VN-Index had established a trend over the past few days to break 580 in the morning but then retreat back in the afternoon. Today it bucked that trend by failing to move above 580 at all and simply testing the lower end of the 570 zone. Cautious sentiment lingering from yesterday's session made the VN-Index fall by 0.8% to reach its intraday low of 567.9 in morning trading.
