The index is showing a very weak price action and the bears are taking it to test the support level of 89.36, at which could gather enough momentum to go towards the 87.88 level. To the upside, it seems the 200 SMA is acting as a dynamic resistance and if it manages to break above that area, the next target lies at 91.75.
