Market Prediction: After opening with a mild 50-point gap-up, Nifty reversed sharply, falling near yesterday’s low within the first hour of trade. What followed was a strong downtrend throughout the session — Nifty closed with a 260-point loss, Bank Nifty shed 530 points, and Sensex tumbled 900 points.
In our previous post, we warned about potential market weakness and advised keeping positions light. That caution played out as today’s market moved decisively downward. Interestingly, despite this strong fall, option premiums didn’t spike significantly, indicating limited volatility and a possible trap for late sellers.
While there’s no major event directly linked to today’s correction, news surfaced about a cyberattack on Zee News servers in Bihar, Jharkhand, and Mumbai — allegedly traced to Bangladesh and Pakistan. This news, combined with Sensex’s weekly expiry effect, may have contributed to negative sentiment.
Let’s analyze the data to decode the next move.

The overall sectoral performance was Bearish.

- Nifty Auto: -2.15%
- Pharma & FMCG: -1.30%

🔍 Technical Analysis – Is this the start of downtrend?
Today’s large red candle follows two smaller bearish candles — this pattern shows increasing selling strength. However, Nifty is still trading within the breakout candle from 15 May (Low: 24,494 | High: 25,116).
Until the low of the breakout candle is breached, we won’t consider the trend fully reversed on the daily timeframe.
Key Levels:
- Support Zone: 24,500 – 24,550
- Resistance Levels: 24,800 & 25,000
On the hourly chart, Nifty has clearly turned bearish, and price is trending below key support zones.
📈 RSI (14) Indicator
- Daily Timeframe RSI: Closed at 58 (below 60), showing weakening momentum. If today’s low is breached, next RSI support is near 50.
- Hourly Timeframe RSI: Dropped below 40, now around 34 — close to oversold territory.
⏱️ Tomorrow’s first hour will be crucial in determining whether a rebound or further fall is likely.

🧠 Nifty 50 Prediction & Trade Plan

- However, Nifty is nearing oversold zones (especially on the hourly chart).
- We’ll consider the trend reversed only if 24,494 (15 May low) is breached.
📌 Trade Strategy:
- Intraday traders should wait for tomorrow’s opening range to assess direction.
- Avoid aggressive long positions unless Nifty reclaims 24,800+.
🧠 Another Expert View
Zee Business Managing Editor Anil Singhvi suggested avoiding long positions at current levels. If holding any, traders should hedge with Put Options to manage risk.
📘 Key Learning from Today’s Market
