Repeated failure to breach 100-DMA support has resulted in a rebound today towards 5-DMA level of 2134.44. However, bearish invalidation is seen only above 50-DMA level of 2166.90.
On the downside, selling is seen gathering pace once 100-DMA support of 2121 is breached on day end closing basis.
In such a case support of rising trendline coming from Feb low and June low seen at 2100 levels could be put to test.
