The USA stock market is the biggest stock market in words. NASDAQ and NYSE stock exchanges have a combined market cap of about 2500 lakh crore rupees while NSE and BSE have a combined market cap of rupee 500 lakh crore.
Any happening in the US stock market directly or indirectly impacts the worldwide stock market. For instance, most DIIs and FIIs Look at the US stock market to decide whether they should invest in the Indian stock market.
There are many other differences between Indian Stock Market and US Stock Market. Like the number of demat accounts. The population of the USA is about 33 crores and India’s is 149 crores but almost 55% of the US population holds a demat account while in India only 9% or 11 crore people hold a demat account and out of that only 3.75 crore people are active traders.
Also, the brokerage Industry of the USA is much different than India in many aspects like size, number, profits and revenue etc.
For instance, there are approx 4500 brokers registered with the Securities and Exchange Commission while in India only 450 brokers are registered with SEBI.
Also unlike the Indian stock market where brokers earn their major revenue from brokerage charges,USA brokers earn their huge revenue from portfolio services, research and advisory etc.
Also, trading apps from US brokers are quite simple unline Indian trading apps which come loaded with lots of features.
The US stock market is more mature than the Indian stock market.
