Nasdaq 100 vs STOXX 600 are yin and yang of interest rates
We have previously tried to calculate the interest rate sensitivity, but this time we are pursuing a different approach. We look at the past 231 trading days this year and group the 1-day difference in the US 10-year yield into deciles. In order to measure interest rate sensitivity we calculate daily excess log returns for Nasdaq 100, S&P 500 and STOXX 600 against the MSCI World Index and compute their average daily excess return for each decile.
As the barplot shows, there is significant negative excess return in Nasdaq 100 in the 1st decile (the 10% days with the highest positive difference in US 10-year yield) and significant positive excess return in STOXX 600. This makes perfect sense because Nasdaq 100 is high duration growth stocks and STOXX 600 has a clear value tilt towards financials, energy and mining which exhibit much lower duration. The pattern is completely reversed in the 10th decline (days with large negative difference in US 10-year yield). The other eight deciles do not show the same clear spread between Nasdaq 100 and STOXX 600. In other words, if interest rates suddenly move aggressively higher then growth portfolio will take a serious hit and hence why we recommend investors to improve the balance between growth and value stocks, or said differently reduce the equity duration.
