Its current price is at 4346.30 down -35.24 points on the day or -0.80%. The low price is approaching the rising 100-hour moving average (blue line in the chart above). That moving average currently comes in at 4339.63.
The last time the price of trade below that 100-hour moving average was back on May 25. Moving below that moving average - and staying below - would increase the bearish bias.

Move below it and it opens the door for further selling probing in the short term from a technical perspective.
