Mercury Laboratories Ltd Upgraded to Sell on Technical Improvements and Valuation Appeal

Quality Assessment: Weak Long-Term Fundamentals Temper Optimism

Mercury Laboratories operates within the Pharmaceuticals & Biotechnology sector, a space often characterised by volatility and regulatory challenges. The company’s quality rating remains subdued due to its weak long-term fundamental strength. Over the past five years, the compound annual growth rate (CAGR) of operating profits has been a mere 0.14%, signalling stagnation in core earnings capacity. This sluggish growth contrasts sharply with sector peers and broader market benchmarks.

Moreover, Mercury Labs has consistently underperformed the BSE500 index over the last three annual periods, with a particularly disappointing one-year return of -5.20% compared to the Sensex’s 9.35% gain. Over three and five years, the stock’s returns of 16.64% and 22.34% respectively lag behind the Sensex’s 36.45% and 62.73%, underscoring persistent underperformance. Such figures highlight structural challenges in the company’s business model and competitive positioning.

Despite these concerns, the company’s return on equity (ROE) stands at a moderate 9%, indicating some efficiency in generating shareholder returns, albeit not at an industry-leading level. The majority shareholding by promoters suggests stable ownership, which can be a positive factor for governance and strategic continuity.

Valuation: Attractive Yet Reflective of Underperformance

From a valuation standpoint, Mercury Laboratories presents a mixed picture. The stock trades at a price-to-book (P/B) ratio of 1.8, which is considered fair and somewhat attractive relative to its peers’ historical averages. This valuation level suggests that the market is pricing in the company’s modest growth prospects and risks.

Further supporting the valuation case is the company’s price-earnings-to-growth (PEG) ratio of 0.7, indicating that the stock may be undervalued relative to its earnings growth potential. Over the past year, profits have increased by 26.7%, a significant improvement that contrasts with the negative stock price return of -5.20%. This divergence implies that the market has yet to fully price in the company’s improving profitability.

However, the weak long-term profit growth and consistent underperformance against benchmarks temper enthusiasm for a higher rating. Investors should weigh the valuation attractiveness against the company’s fundamental challenges and sector risks.

Financial Trend: Recent Quarterly Performance Shows Encouraging Signs

Mercury Laboratories’ latest quarterly results for Q3 FY25-26 reveal positive momentum in financial performance. The company reported its highest quarterly PBDIT at ₹2.52 crores and an operating profit margin to net sales ratio of 13.73%, the best in recent periods. Additionally, the profit after tax (PAT) for the latest six months stood at ₹2.91 crores, reflecting a robust growth rate of 72.35% compared to prior periods.

These figures indicate an operational turnaround and improved cost management, which could provide a foundation for future growth. Nevertheless, the long-term CAGR of operating profits remains subdued, signalling that these improvements may be early-stage or cyclical rather than structural.

Investors should monitor upcoming quarters closely to determine if these positive trends can be sustained and translated into consistent earnings growth.

Technical Analysis: Upgrade Driven by Improved Market Sentiment

The primary catalyst for the recent upgrade from Strong Sell to Sell is the improvement in technical indicators, which have shifted from bearish to mildly bearish or mildly bullish in some cases. This technical shift suggests a stabilisation in market sentiment and potential for price recovery in the near term.

Key technical metrics include the Moving Average Convergence Divergence (MACD), which remains bearish on a weekly basis but has softened to mildly bearish on the monthly chart. The Relative Strength Index (RSI) shows no clear signal on both weekly and monthly timeframes, indicating a neutral momentum. Bollinger Bands and daily moving averages have also improved to mildly bearish levels, reflecting reduced downward pressure.

Notably, the Dow Theory indicator is mildly bullish on a weekly basis, signalling a tentative uptrend, although it remains mildly bearish monthly. The stock’s price has risen 1.87% on the day to ₹815.30, trading within a 52-week range of ₹736.00 to ₹976.00. Recent returns outperform the Sensex over short-term periods, with a 1-month return of 2.54% versus the Sensex’s 0.77%, and a 1-week return of 1.26% compared to 0.23% for the benchmark.

These technical improvements underpin the upgrade in rating, reflecting a more favourable near-term outlook despite the company’s fundamental challenges.

Comparative Performance and Market Context

While Mercury Laboratories has shown some recent improvement, its long-term returns remain below market averages. Over ten years, the stock has delivered an 83.42% return, significantly trailing the Sensex’s 249.29% gain. This gap highlights the company’s historical underperformance and the challenges it faces in closing this disparity.

Short-term returns have been more encouraging, with the stock outperforming the Sensex over one week and one month periods. Year-to-date, Mercury Labs has gained 0.51%, while the Sensex has declined by 2.82%, suggesting some resilience amid broader market weakness.

Investors should consider these relative performance metrics alongside the company’s financial and technical indicators when making investment decisions.

Outlook and Investment Considerations

The upgrade to a Sell rating from Strong Sell reflects a cautious but more optimistic stance on Mercury Laboratories. The improved technical indicators and recent quarterly financial results provide a foundation for potential recovery. However, the company’s weak long-term fundamentals, modest profit growth, and consistent underperformance against benchmarks warrant continued vigilance.

Valuation metrics suggest the stock is fairly priced, with some upside potential given the PEG ratio and profit growth. Yet, investors should remain mindful of sector risks and the company’s ability to sustain operational improvements.

Overall, Mercury Laboratories may appeal to investors seeking a turnaround story with improving technical signals but remains a speculative proposition given its fundamental constraints.

Summary of Ratings and Scores

As of 20 Feb 2026, Mercury Laboratories holds a Mojo Score of 34.0 with a Mojo Grade of Sell, upgraded from Strong Sell. The Market Cap Grade is 4, reflecting its micro-cap status within the Pharmaceuticals & Biotechnology sector. Technical grades have shifted from bearish to mildly bearish, supporting the rating upgrade. Investors should weigh these factors carefully in the context of their portfolio strategies.
