Microsoft's Strong Run Raises Questions About Its Value as a Safe Haven

Microsoft (MSFT) has outperformed the S&P 500 in recent trading days, but whether this is due to its own merits or simply a reflection of the broader market's performance is an important question for long-term investors.

The correlation between Microsoft and the S&P 500 over the past five years is 0.69, indicating that it closely tracks the index. However, Microsoft's return of 11.5% per year at 28.1% annualized volatility is less impressive than the S&P 500's 12.7% return at 17.2% volatility.

A closer look at what drives Microsoft's revenue growth reveals a mixed picture. While Azure revenue grew 43% in fiscal Q4 2026, Windows OEM and Devices revenue is expected to decline by high teens across fiscal 2027 due to softer PC demand. This suggests that the company's fortunes are closely tied to the overall economy.

Microsoft's operating margin of 46.8% is a strong argument for holding the stock, but it does not necessarily provide diversification benefits. In fact, Microsoft's returns are highly correlated with the S&P 500, making it more akin to an index fund than a true diversifier.
