A screening process using Peter Lynch's PEG ratio has highlighted Sky Gold & Diamonds, Waaree Renewable Technologies, and P N Gadgil Jewellers. These companies show strong growth trends, but investors should weigh their valuations and operational challenges before drawing conclusions.
What Happened
A recent financial screening process inspired by investor Peter Lynch’s 'Growth at a Reasonable Price' (GARP) methodology has identified three Indian mid-cap companies. By using a PEG (Price/Earnings to Growth) ratio filter, the analysis sought to find businesses with strong profit and sales growth, manageable debt, and healthy capital efficiency, rather than just cheap valuations. The companies highlighted in this filter include Sky Gold & Diamonds, Waaree Renewable Technologies, and P N Gadgil Jewellers.
The PEG Ratio Approach
Peter Lynch’s method relies on the PEG ratio to determine if a stock’s valuation is justified by its earnings growth. A PEG ratio below 1.5 is often used to flag stocks where the growth potential might outweigh the current price multiple. However, this is only a starting point for investors. While numerical screens help narrow down a vast market, they look at historical or current data. Investors must remember that past performance, while useful, does not guarantee future results, and current valuations must be weighed against future growth prospects.
Sky Gold & Diamonds: Growth and Debt Plans
Sky Gold & Diamonds, which operates a B2B model in the gold jewelry space, posted strong FY26 results with a 77.4% rise in revenue to ₹6,294.9 crore and a 112.4% jump in net profit to ₹281.8 crore. The company is actively focused on improving its cash cycle, reducing its working capital days from 71 to 59, and aiming to be net debt-free by FY30. While the capital efficiency ratios (ROCE of 27% and ROE of 29.2%) appear healthy, the stock trades at an EV/EBITDA of 18.8 times, which is higher than the industry median. Investors may want to monitor if the company can sustain its growth rate to justify this premium valuation.
Waaree Renewable Technologies: Efficiency and Order Book
Waaree Renewable Technologies, focused on the renewable energy sector, reported an FY26 revenue of ₹3,331.4 crore, a 108.5% increase. Profits rose by 109.1% to ₹478.6 crore. The company's business model is supported by a solar EPC order book of 2.83 GWp and an operations and maintenance portfolio of 1.18 GWp. With an ROCE of 85.4% and ROE of 69.1%, the company demonstrates high capital efficiency. Unlike many peers, its EV/EBITDA valuation of 15.9 times sits below the sector median. The main monitorable here is the ability to execute its large order book on time.
P N Gadgil Jewellers: Retail Expansion and Margin Risks
P N Gadgil Jewellers reported revenue of ₹10,739 crore for FY26, a 40% increase, while profits grew 88% to ₹410 crore. The company has been in an aggressive expansion phase, adding 25 new showrooms in FY26, bringing its total to 78. While the company has solid return ratios (ROCE 20.9%, ROE 23.4%), there is a clear operational risk: profit margins faced pressure in the final quarter due to a higher proportion of sales coming from gold bars and coins, which are lower-margin products compared to jewelry. The stock trades at an EV/EBITDA of 12.2 times, slightly above the industry median.
What Investors Should Track
Quantitative screens are only the first step. For Sky Gold, the ability to meet its debt-reduction targets is a key monitorable. For Waaree, future revenue visibility will depend on the speed of executing its 2.83 GWp order book. For P N Gadgil, investors should watch if the company can shift its product mix back toward higher-margin jewelry to protect its profitability, especially as it continues to expand its retail footprint.
