Data note
The number that isn’t in the index factsheet
An index factsheet will tell you the sector weights, the constituent count and the top ten holdings. It will not tell you how much of each company a foreign investor is actually permitted to own, or how much of that allowance is already used. That number, foreign room, sits in regulatory filings and index methodology notes, and it decides more about a foreign India allocation than most of what the factsheet reports.
The mechanics matter because the index a foreign allocator can buy holds the float foreigners are allowed to hold, not the economy. Where ownership limits bind, or promoter holdings crowd out the float, index weight and economic weight part company. And the places where they part company most are not random; they tend to be the most domestically owned parts of the market.
The flagship study, Can Global Investors Actually Capture India’s Economic Rise?, works through the full argument: foreign ownership limits, free float, foreign room, and what the gap between MSCI India and India means for an allocation decision, inside a ten-market comparative frame.
