In this article published earlier, we discussed that both the markets, equity and debt, look stretched on valuations. At that point of time, the yield on the 10-year government security was approx 6.5% and the overnight interest rate, represented by the RBI repo rate, was 6.25%. The spread was only 25 basis points between overnight and 10-years. This was an anomaly as per the theory of time value of money because the compensation was only 25 basis points for sparing money for 10 years.

Since then, the RBI has cut policy rate in August ’17, thereby bringing the overnight rate to 6%. The bond market has corrected and the 10-year G-Sec yield currently is at around 7.35%, taking the average of the existing benchmark 6.79% GoI 2027 and the new benchmark 7.17% GoI 2028. The 10-year to overnight spread at approx 1.35% is attractive.

The equity market has run up further since July '17. The PE Ratio in July ’17 was approx 25 on trailing EPS basis. Currently, it is approx 27.5 on trailing EPS basis. As per the thumb rule to figure out the relative attractiveness between the two markets i.e. equity and debt, the inverse of the 10-year bond yield is compared with the equity PE. Inverse of 7.35% is 13.6, which denotes that if the equity PE is at or less than 13.6, equity is very attractive. Now that equity PE is at approx 27.5, it is not cheap. However, the equity market may witness a PE rerating driven by better earnings growth. Since there is a discounting of future growth in equities, which is not the case with bonds, some premium is justified.
