The Nifty 50 is unlikely to easily break out of the bear grip, given the weakening technical structure across parameters and US Treasury yields hovering near two-decade highs. The index fell a third of a percent on September 29, the monthly F&O expiry session, despite a sharp recovery from the day's low. It has declined 5.67 percent in September so far. According to experts, Tuesday's low of 22,570 is expected to be a crucial level. A break below this level could trigger further downside towards the 200-week EMA at 22,380 and then the April low of 22,182. On the other hand, holding above 22,570 could drive the index towards the 22,800–23,000 zone. Experts continue to advise a sell-on-rallies strategy.
