How India compares with other markets

The United States remained the largest share of the global market, holding nearly 48–49% of total market capitalization in the same period. China, Japan and Hong Kong follow after the US. Over the past year, most major markets (except India and Brazil) recorded gains in market capitalization.

Why this matters — plain language

A country’s share of global market capitalization is one way to see how big its stock market is compared with the world. When India’s share falls, it means two possible things:

1. Other countries’ markets are growing faster (more foreign or domestic investment there).
2. India’s market value has dropped (prices fell or some companies lost value).

For investors, a falling share can mean less global weight for India in international funds and indexes. It can affect foreign flows, index weights, and sentiment.

What pushed India down (simple causes)

Motilal Oswal and market reports point to a mix of factors: slower earnings for some large firms, profit-taking after earlier highs, and stronger gains in other markets (China, Korea, Taiwan, US). Macro and policy factors can also affect flows.

What investors can do (basic checklist)

• Review portfolio diversification — don’t rely on one market or sector.
• Focus on long-term fundamentals: earnings growth, valuations, and quality companies.
• Watch global flows and index re-weighting news that can change foreign investment patterns.
• Consider rebalancing if domestic allocations no longer match risk goals.
