15 September 2026: Sharp Opening Decline Amid Market Sell-Off
Thermax commenced the week on a weak note, closing at Rs.3,558.65, a decline of 3.30% from the previous Friday’s close of Rs.3,680.25. This drop coincided with a broader market sell-off, as the Sensex fell by 1.69% to 35,169.62. The stock’s volume of 6,853 shares reflected active trading amid the negative sentiment. The decline was exacerbated by concerns over valuation and technical indicators, which began to signal a loss of upward momentum.
16 September 2026: Technical Momentum Shifts and Valuation Concerns Trigger Downgrade
On 16 Sep, Thermax’s share price slipped further by 0.56% to Rs.3,538.75, despite the Sensex gaining 0.30% that day. This divergence highlighted company-specific pressures. The day’s trading range between Rs.3,514.50 and Rs.3,719.95 underscored heightened volatility. Crucially, technical analysis revealed a shift from a mildly bullish to a sideways trend, with bearish weekly MACD and Bollinger Bands indicating potential short-term weakness. The Relative Strength Index remained neutral, suggesting indecision among investors.
Simultaneously, valuation metrics raised red flags. Thermax’s price-to-earnings ratio stood at an elevated 77.14, with a price-to-book ratio of 7.64, both significantly above sector averages. Enterprise value multiples also reflected stretched pricing, with EV/EBITDA at 48.63 and EV/EBIT at 64.93. These factors contributed to a downgrade in the company’s Mojo Grade from Hold to Sell, signalling increased caution.

17 September 2026: Modest Recovery Amid Mixed Market Signals
Thermax rebounded modestly on 17 Sep, gaining 0.84% to close at Rs.3,568.35, while the Sensex also advanced 0.46% to 35,439.31. The recovery was supported by daily moving averages that remained mildly bullish, providing short-term support despite the broader sideways trend. However, volume declined to 3,940 shares, indicating cautious participation. The mixed technical signals, including a bullish monthly MACD and KST, contrasted with bearish weekly indicators, reflecting uncertainty about the stock’s near-term direction.
18 September 2026: Week Ends with Slight Decline Amid Continued Volatility
The week concluded with Thermax slipping 0.50% to Rs.3,550.45 on 18 Sep, even as the Sensex rose 0.52% to 35,625.23. Trading volume surged to 7,238 shares, suggesting renewed investor activity amid the stock’s consolidation phase. The price remained well below the 52-week high of Rs.5,277.00 but comfortably above the 52-week low of Rs.2,744.20, underscoring the stock’s wide trading range over the past year. The technical and valuation concerns persisted, maintaining a cautious outlook.
