Well not wanting to hijack this post so I’ll be very brief
The best option for direct investment in stocks would be to look for a broker in India that provides investment in US stocks. Vested is one of the platform among discount brokers (not recommending as I have never used them) and then you have big players like ICICI Direct, HDFC Sec etc.
The brokerage charges are not particularly high and you can also buy fractional shares.However,the major pain point is transfer of money from India to US trading account which could eat in your capital by almost 10% before even you take a trade and then currency risk , redeeming profits and all sorts of things.
I would say it is better suited if you have good investment capital where remittances and brokerages will only make a small dent when compared to profits realised.
