Global Funds Share Tech Exposure, Risking Diversification
Adding US and Asian funds does not guarantee distinct risks. Correlations surge above 0.8 during market stress, undermining the value of geographic spreads.
Key points
- Correlations between the S&P 500 and Asian markets exceed 0.8 during periods of stress.
- Information technology makes up 37% of the US market compared to 6.5% in the Nifty 500.
- The Nasdaq 100 contains roughly 66.4% information technology exposure and excludes financials.
Correlations between the S&P 500 and major Asian markets exceed 0.8 during stress. This high linkage undermines the perceived benefit of geographic diversification. Investors often assume that holding assets across five countries creates five distinct risk profiles. In reality, the underlying earnings drivers remain heavily concentrated in the same technology sectors.
Most Indian investors hold core equity exposure through the Nifty 500 index. They then add positions in the United States, Taiwan, and South Korea to broaden their reach. On paper, this creates a geographically diverse portfolio. However, the fundamental exposure to semiconductors and AI spending remains highly overlapping across these different markets.
Geographic spread masks sector concentration
Taiwan’s market is dominated by a single semiconductor manufacturer. South Korea’s index relies heavily on two major electronics firms. Emerging market indices also carry significant weights in these same companies. Consequently, adding multiple international funds often results in repeated exposure to identical technology themes.
Radhika Gupta of Edelweiss Mutual Fund notes that international investing must add different growth drivers. It is not enough to simply add another geography to the mix. Investors should evaluate what actually drives a company’s earnings rather than just where it is listed. This approach prevents portfolios from being driven by the same global demand cycles.
Distinct economic engines drive returns
The Nifty 500 reflects India’s domestic credit cycle and consumption patterns. Its economic engines differ materially from those of the S&P 500. Combining these two indices provides genuine diversification based on different fundamental drivers. This strategy aligns India’s domestic demand opportunity with the global innovation cycle.
Information technology accounts for 37% of the US market versus 6.5% in India. This sector gap is the primary case for adding US exposure. However, investors must track their combined sector exposure rather than just the country split. Ignoring this overlap can lead to a false sense of security in a diversified portfolio.
Index selection affects risk profile
Many investors treat the Nasdaq 100 as interchangeable with the S&P 500. This is a significant mistake for portfolio construction. The Nasdaq 100 excludes financials entirely and concentrates roughly 66.4% in information technology. This makes it a much narrower bet on non-financial technology growth.
The S&P 500 offers broad exposure across healthcare, financials, and industrials. It provides a more balanced view of US business performance. According to indiatimes.com, understanding these structural differences is critical for effective allocation. Choosing the right index ensures that the added risk is distinct from existing holdings.
