Weekly market wrap: Cochin Shipyard, Servotech Renewable among 10 stocks that gained over 20% this week; check full list

Indian equity markets saw a strong rebound this week, with SENSEX gaining 0.91% and the NIFTY50 rising 1.02%. The sharp uptick was primarily driven after the Reserve Bank of India (RBI) unexpectedly cut its repo rate by 50 bps to 5.50%, which was larger than market expectations of a 25 bps reduction. In addition, the RBI cut the cash reserve ratio (CRR) by 100 basis points, bringing it down from 4% to 3%.

These policy moves boosted investor sentiment, especially in rate-sensitive sectors. Furthermore, the RBI’s revised gold loan guidelines, raising the LTV cap for small borrowers and easing appraisal norms were also well-received by markets, particularly benefiting NBFCs and cooperative lenders. Despite early-week caution due to geopolitical tensions, the market rallied in the latter half, reflecting optimism on domestic monetary policy support and broader credit access reforms.

10 stocks which rose 20% and above

*CMP and Market cap as of June 6 closing

Astrazeneca Pharma

Astrazeneca Pharma India reported its January-March quarter results post-market hours last Friday. The company reported a robust 32% year-on-year revenue growth in FY25, crossing the ₹1,700 crore mark for the first time. This performance was driven by strong momentum across therapeutic areas—especially oncology and biopharmaceuticals—along with new innovative medicine launches. The company reiterated its commitment to delivering sustainable value through its science-led, innovation-driven portfolio.

Sika Interplant

Sika Interplant has signed a key license agreement with Collins Aerospace units in France and the UK, allowing it to provide MRO services for specific flight control components. Despite this positive development, its stock has been placed under the long-term ASM framework by BSE and NSE due to high price volatility. The company operates across engineered systems, interconnect solutions, MRO services, and value-added distribution.

Avantel

India's armed forces have begun emergency procurement to bolster defence readiness, targeting loitering munitions, anti-tank missiles, counter-UAV systems, and artillery shells, up to 15% of the ₹1.6 lakh crore defence modernisation budget. Avantel, known for its defence electronics and communication systems, is benefiting from this heightened focus on military preparedness. With defence a strategic priority, investor optimism remains strong for companies like Avantel.

Servotech Renewable Power

Shares of Servotech Renewable Power System surged following the visit of Errol Musk, father of Elon Musk, to India, where he is offering strategic advisory support to the company’s solar and EV charging divisions. His involvement—highlighted by factory visits, stakeholder meetings, and global promotion has fueled investor optimism. The rally also follows recent order wins, including a ₹15 crore solar project from Indian Railways.

Other Stocks that rose over 20%

HMT, Elitecon International, and Oriana Power all clocked 20%-plus weekly gains on sector-specific tailwinds and renewed buying in smaller industrial names, while Cochin Shipyard’s rally was powered by fresh global defence-spending rhetoric from US and NATO leaders, which re-energised sentiment toward Indian naval and aerospace suppliers. Meanwhile, Lumax Auto Technologies soared as investors cheered its roadmap to triple revenue to ₹10,000–11,000 crore by FY3, underpinned by a bulging order book, clean-mobility plays, and bolt-on acquisitions set to lift EBITDA margins to 16%. Together, these counters illustrate how targeted policy cues and credible long-term growth blueprints can unlock outsized short-term moves in India’s mid- and small-cap universe.
