The benchmark indices continued their positive momentum, with the Sensex rising by 274 points. In addition, a bullish candle on daily charts and an uptrend continuation formation on intraday charts indicate a strong possibility of fur-ther uptrend from the current levels. “For trend-following traders, now 77,500 would act as a key support zone,” says Shrikant Chouhan, Head - Equity Research, Kotak Securities. Above this, the uptrend wave is likely to con-tinue. On the flip side, below 77,500, the uptrend would become vulnerable.
