Dalal Street Masterclass: Two Losing Trends That Shaped Last Week; More New Lessons in Store For Investors This Week?
By HDFC SKY | Updated at: May 18, 2026 10:33 AM IST

Mumbai, May 18: The week of May 11–15 on Dalal Street was not simply a story of markets rising and falling. It was a masterclass in how quickly momentum builds, how brutally it reverses, and how war-driven macro shocks expose the fault lines in portfolios that investors thought were safe.
Two distinct losing trends ran through the week one born from geopolitical shock at Monday’s open, the other from a violent unwind of the week’s most crowded trade by Friday’s close. Both carry lessons that extend well beyond this week.
Trend One: The Geopolitical Shock Selloff – When Macro Overwhelms Everything
Monday opened with a single headline that changed the market’s entire risk calculus: Trump had flatly rejected Iran’s latest peace proposal over the weekend, and crude oil surged $3 a barrel overnight. The Sensex shed 870 points at the open and the selling was indiscriminate Titan crashed 6.85 per cent to ₹4,200, IndiGo fell 4.73 per cent, SBI declined 4.36 per cent, Eternal dropped 4.03 per cent, Jio Financial Services slid 3.81 per cent and Bharti Airtel fell 3.79 per cent. Forty-seven of fifty Nifty stocks declined. India VIX surged above 19.
What unified these stocks was not sector it was valuation. Every one of these was a premium-priced name carrying elevated expectations into a macro environment that had just become dramatically more hostile. When fear enters a market this quickly, fund managers sell what they can, not what they want to and the most liquid, most visible, highest-valued names on the index become the first casualties regardless of their underlying business quality.
Why this trend matters going forward:
- Every fresh escalation from the Strait of Hormuz will trigger an identical reflexive selloff in high-valuation index heavyweights, because the pattern is now established and algorithmic trading desks will replicate it faster each time
- The rupee hitting successive record lows 95.63 on Tuesday and beyond 96 by Friday creates a sustained inflation anxiety that keeps risk appetite structurally suppressed and makes premium valuations harder to defend in every subsequent session
- SBI’s decline reflected a broader concern that elevated crude prices and a weakening rupee will eventually pressure credit quality in rate-sensitive segments, a worry that does not resolve until energy prices stabilise
- High-expectation growth stocks like Eternal and Jio Financial are structurally the most vulnerable in this environment because their valuations price in a benign macro future that the Iran conflict is actively undermining
- This selling trend will return with force every time diplomatic progress stalls as it did when Iran and the US rejected each other’s proposals last week — because the market has learned that hope in this conflict has a very short shelf life
Trend Two: The Metals Unwind – The Week’s Most Crowded Trade Collapses
What went up fastest came down hardest. Metals had been the week’s most spectacular trade — SAIL surged 14 per cent on Wednesday alone in what analysts later identified as a short squeeze, Hindustan Zinc rode silver’s rally driven by the import duty hike, and Vedanta hit a one-year high on Thursday. By Friday, the entire sector was in freefall. Hindustan Zinc dropped over 4 per cent, Vedanta fell 2.7 per cent, Hindustan Copper crashed nearly 5 per cent, and SAIL extended its retreat for a second straight session, down 2.28 per cent after its speculative-driven surge had fully exhausted itself.
The trigger was a sharp 7 per cent reversal in global silver prices on Friday, driven by strengthening expectations of a US Federal Reserve rate hike. A stronger dollar mechanically deflates commodity prices, and Hindustan Zinc — which derives a significant portion of revenues from silver — bore the full weight of that reversal. The government’s import duty hike on gold and silver had initially provided a sentiment boost, but that was a one-session catalyst that the market had already fully absorbed by Thursday’s close.
Why this trend matters going forward:
- SAIL’s 14 per cent Wednesday rally was never built on fundamentals it was a short squeeze where aggressive bearish bets were forcibly closed as prices rose, creating a momentum feedback loop that always unwinds violently once the squeeze is exhausted, as it did with a vengeance on Thursday and Friday
- Fed rate hike expectations will remain a persistent and unpredictable overhang on the entire metals complex for the remainder of the quarter, meaning multi-day rallies in the sector should be treated as trading opportunities rather than trends worth holding through
- The import duty hike on precious metals was a policy measure aimed at conserving foreign exchange, not a structural earnings driver once priced in, it offered no recurring catalyst and the sector was left exposed to global price movements without any domestic policy cushion
- Valuations stretched dangerously across the sector after four consecutive days of buying, leaving no margin of safety when sentiment shifted the absence of fresh buyers at elevated prices meant sellers dominated every counter simultaneously with no support visible until much lower levels
- Silver ETFs, which had surged dramatically during the week on the import duty excitement, witnessed equally sharp selling on Friday, confirming that the entire precious metals trade equities and instruments alike — was driven by short-term momentum rather than conviction buying
