In India, brokers usually sell your oldest shares first (FIFO). For swing trades, use your broker's "tags" to keep them separate from long-term holdings. Pick stocks with good momentum, set stop-losses, and monitor the one-year mark to save on taxes.

If you're planning to invest in S&P 500 ETFs for the next 15 years, you have several amazing options. US-based platforms like Vanguard, Fidelity, and Schwab are known for their secure services and low-cost ETFs.

For those in India, platforms such as Zerodha, Groww, Kuvera, and Appreciate provide access to US ETFs, each with different fee structures and user experiences. Select the platform that best suits your needs.
