📌 Chapter 10.4 — Approaches to valuation

Imagine you are drafting an initiation note for a mid-cap IT services firm listed on the NSE. Your DCF model shows a robust internal rate of return, but your senior analyst stops you: ‘Your discount rate is too optimistic; you haven’t properly accounted for the India-specific equity risk premium.’ This moment is critical because the discount rate, typically the Weighted Average Cost of Capital (WACC), serves as the anchor for your entire valuation.

If your risk premium is miscalculated, your valuation reflects a level of safety that does not exist in the volatile reality of mid-cap equities.

The Equity Risk Premium (ERP) represents the additional return investors demand for holding risky equity over a risk-free asset, such as a 10-year Government of India bond. Calculating this is not a mechanical exercise but a judgment-based one that requires balancing historical data with forward-looking expectations. An analyst must decide whether to use a long-term historical average or an implied ERP, which is derived by backing out the rate from current market prices.

While historical averages provide stability, they may fail to capture structural shifts in the Indian economy, such as changing inflation expectations or liquidity conditions.

Consider the impact on your recommendation: if you assume an ERP that is too low, you effectively lower your denominator, leading to an inflated intrinsic value. This results in an ‘Overweight’ rating on a stock that might actually be overvalued. Conversely, a high-risk premium applied indiscriminately across all sectors ignores the defensive nature of firms in the FMCG or pharmaceutical space. Proper calculation requires segmenting your risk assessment by Beta—which measures systematic risk—and then layering on specific risk premiums for size, illiquidity, or operational leverage.

Ultimately, your choice of risk premium dictates the ‘hurdle rate’ every project or stock must clear to justify an investment. When you provide a valuation to a client, you are implicitly stating that the potential returns justify the risk taken. By rigorously documenting your ERP assumptions and testing them against market consensus, you ensure your valuation holds up under the scrutiny of an institutional investment committee. Master the inputs of your WACC, and you move from being a data reporter to a genuine financial analyst.

Nuance

⚠️ Nuance
Many candidates incorrectly treat the ERP as a single, static figure applicable to the entire market. In practice, seasoned analysts frequently apply ‘Size Premiums’ to mid-cap or small-cap stocks to account for their higher sensitivity to economic cycles and lack of market liquidity. Failing to adjust the ERP for company-specific risk factors often leads to an aggressive valuation that neglects the realities of Indian small-cap volatility.
