Most investors going global do not want to pick individual companies. They want exposure to a market, and that is what an index fund or ETF provides.
The complication for an Indian investor is that the same exposure is available through several structures, and they are not equivalent. Buying a US-listed S&P 500 ETF directly under the LRS gives you dollar-denominated ownership and one tax treatment. Buying an Indian feeder fund that invests in the same index keeps your money in rupees and gives you a different tax treatment. A GIFT City route differs again.
None of these is universally better. They differ on ownership, control, cost, currency exposure and — most consequentially — how the gains are taxed. The articles here set the routes side by side so the trade-off is visible before you commit, and explain the metrics that actually matter when comparing funds.
Nothing here is a recommendation of any specific fund. Named funds appear only as neutral illustrations of structure.
