Is Blue Star overvalued or undervalued?

As of 18 August 2025, Blue Star's valuation grade has moved from fair to expensive, indicating a shift in its market perception. The company is currently considered overvalued based on its high valuation multiples, including a PE ratio of 73.58, an EV to EBITDA of 46.34, and a PEG ratio of 10.94. These figures suggest that investors are paying a premium for the stock relative to its earnings growth potential. In comparison to its peers, Blue Star's valuation stands out, with Voltas having a PE of 68.92 and EV to EBITDA of 51.04, while Johnson Controls is even higher at a PE of 118.15 but with a lower EV to EBITDA of 41.83. This positions Blue Star as the most expensive among its peers, raising concerns about its sustainability at these valuation levels. Additionally, while Blue Star has outperformed the Sensex over the long term, its recent YTD return of -9.98% contrasts sharply with the Sensex's 4.01% gain, further supporting the notion that the stock may be overvalued at its current price of 1915.20.
