Diwali 2026: Sensex plunged 10,000 points, Nifty dropped 12% since last Diwali. Will Samvat 2083 bring some relief?

The Economic Times headline reports that the BSE Sensex has fallen by roughly 10,000 points and the NSE Nifty 50 has declined about 12% over the twelve months leading up to Diwali 2026, with the piece asking whether the start of the Samvat 2083 trading year may offer a reprieve. The drawdown is a risk-appetite signal: a double-digit fall in India's benchmark indices typically reflects some combination of foreign portfolio outflows, earnings downgrades, or repricing of domestic growth expectations, though the headline itself does not specify the driver. Large-cap heavyweights in banking, financials, and consumer names, which dominate index weights, are typically the most exposed to shifts in foreign institutional flows and domestic credit sentiment. Traders should watch the next release of foreign institutional investor flow data from NSDL and the upcoming RBI monetary policy decision, since any change in rate expectations or net FII buying would indicate whether the Samvat-period narrative of relief has a fundamental basis.

HIGH-impact news is typically a market-moving event with multi-pip or multi-percent intraday reactions. Examples include central bank rate decisions, major CPI/NFP releases, geopolitical shocks, mega-cap earnings beats/misses, and regulatory announcements. Traders typically position-reduce or hedge ahead of scheduled HIGH-impact events, and follow the wire in real time to react to unscheduled ones (war headlines, central-bank emergency statements, surprise corporate actions). The Trading News Terminal squawk box reads every HIGH-impact headline aloud the moment it hits the wire — so active traders don't have to stare at the feed.

Active traders typically follow a three-step workflow when a market-moving headline hits the wire: (1) read the headline on the terminal or hear it on the squawk box; (2) assess whether the news is already priced in (by checking intraday price action in the seconds before) or whether it's genuinely new information; (3) act — either entering a breakout position, fading an overreaction, or tightening stops on existing trades. Trading News Terminal's Pro plan delivers wire-grade headlines within seconds of the source, with automatic audio squawk on every HIGH-impact event, so the read-assess-act cycle never waits on a refresh button.
