Trend breakdown — Sensex / Nifty / stock market: Why the market is down today — 10 point explainer

1. Immediate trigger — U.S. tariffs on branded pharmaceuticals.
   President Trump’s announcement of steep tariffs (including a 100% levy on certain branded/patented drugs) rattled global pharma flows and triggered a sharp sell-off in India’s pharma pack. Indian pharma stocks led losses on the day. (Reuters)

2. H-1B fee/executive action hit IT sentiment.
   A new six-figure fee / executive action on H-1B entry and fees has raised near-term demand worries for Indian IT exporters — this dented IT names and compounded the sell-off. (Reuters)

3. Foreign portfolio investors (FPIs) selling — sustained outflows.
   FPIs have been net sellers in September (part of a larger run of flows in 2025), adding selling pressure that magnified declines in large-cap and growth names. (Business Standard)

4. Rupee weakness tugged on sentiment.
   The INR weakened to record lows in the week (near ₹88.79/$), tightening pressure on foreign investor appetite and corporate earnings expectations for dollar-exposed firms. Central bank intervention limited further immediate falls, but currency weakness still dampened mood. (Reuters)

5. Pharma and IT led the sectoral losses — breadth turned negative.
   Nifty Pharma and Nifty IT were among the top losers; over 100 Nifty 500 firms lost >3% on the day. Broad market declines (thousands of stocks down) amplified index weakness. (The Economic Times)

6. Technical damage — short-term trend broke; 200-day DEMA watched.
   The Nifty lost ~3% over six sessions and analysts flagged the 200-day DEMA (~24,400 area) as a key technical support to watch — a breach could invite further selling from momentum strategies. India VIX rose, indicating rising short-term volatility. (Moneycontrol)

7. Mid and small caps underperformed — profit booking across the board.
   Mid- and small-cap indices fell harder than large caps as risk-off flows sought liquidity; many stocks saw multi-session losses. Market breadth metrics showed a decisive skew toward decliners. (ET Now)

8. Global macro & risk-off cues (trade + rate uncertainty).
   Broader global headlines — trade tensions, U.S. policy moves and macro data volatility — kept investors cautious and reduced the risk appetite that had supported recent rallies. (Reuters)

9. Liquidity / reserves & policy context — limited cushion.
   India’s forex reserves ticked down modestly the week, and while RBI intervention helped the rupee intraday, the combination of outflows and currency stress tightened the margin for complacency. (The Economic Times)

10. Near-term outlook — knee-jerk to news; focus shifts to earnings & macro.
    Analysts say the move is driven by headline risk (tariffs & H-1B) + flows; if data (earnings, capital flows or macro prints) stabilise next week, a rebound is possible. Conversely, continued FPI outflows or further policy shocks could extend the correction. (Moneycontrol)
