Scarce

Investors love the promise of high returns from emerging-market equities, but there are not many of them to buy. Especially if you exclude stakes held by governments, the market capitalisation of bourses beyond the rich world is tiny. Just how tiny is apparent from the map below: in many emerging markets, the value of all the freely traded shares of firms that feature in the local MSCI share index (which typically tracks 85% of local listings) is equivalent to a single Western firm. Thus all the shares available in India are worth roughly the same as Nestlé; Egypt’s are equal to Burger King. This suggests that emerging economies need deeper, more liquid markets-and investors need more perspective.
