Understanding the US Stock Market
When the US market is open in IST, which exchange is which, and what the headline indices actually track.
Start here.
US market timings in IST including the daylight-saving shift, how NYSE and NASDAQ differ, what the S&P 500, Dow Jones and Nasdaq 100 actually measure, and access to markets beyond the US.
The US market runs on a different clock and a different structure from the one Indian investors know. Regular trading is 9:30 AM to 4:00 PM New York time: 7:00 PM to 1:30 AM IST while the US is on daylight time, and 8:00 PM to 2:30 AM IST while it is on standard time (early November to mid-March). The market closes on US holidays, and some days close early; pre- and post-market trading, where your account allows it, runs outside these hours. The hour shifts twice a year, which catches people out.
Structurally, it helps to keep two things apart that are often confused. NYSE and NASDAQ are exchanges — venues where shares change hands. The S&P 500, the Dow Jones Industrial Average and the Nasdaq 100 are indices — measurements of baskets of shares. A company listed on NASDAQ may well be in the S&P 500; the two facts are unrelated.
The articles here cover the timings in practical terms, the exchange-versus-index distinction, and how a US brokerage account also opens the door to European, Japanese and emerging-market exposure.

Asked most often about Understanding the US Stock Market
Answered here word for word as they are published to search engines as structured data. Nothing is summarised for the page.
What are US stock market timings in Indian Standard Time?
Regular US trading hours are 7:00 PM to 1:30 AM IST during US daylight saving time (roughly March to November) and 8:00 PM to 2:30 AM IST during US standard time (roughly November to March). The one-hour shift happens because the US changes its clocks and India does not.
Can I trade US stocks before or after regular hours?
Pre-market corresponds to roughly 1:30 PM to 7:00 PM IST during US daylight saving time, and 2:30 PM to 8:00 PM IST when the US is on standard time (early November to mid-March); after-hours runs from the close. Availability depends on your broker. Liquidity is thinner and bid-ask spreads are wider in these sessions than during regular hours, so orders can fill at prices further from the last traded price.
What is the difference between NYSE and NASDAQ?
Both are US stock exchanges. The NYSE is the older venue and has historically used a hybrid model with designated market makers on a physical floor; NASDAQ is fully electronic and has a heavier concentration of technology listings. For a retail investor buying a listed share, the practical difference is minimal.
What is the difference between the S&P 500, the Dow and the Nasdaq 100?
The S&P 500 tracks 500 large US companies weighted by market capitalisation. The Nasdaq 100 tracks the largest 100 non-financial companies listed on NASDAQ, so it is technology-heavy; it is a 100-company subset, not the full list of NASDAQ-listed companies. The Dow Jones Industrial Average tracks just 30 companies and weights them by share price rather than company size, which makes it the least representative of the three.
Does the Indian market being closed matter when I trade US stocks?
It works in your favour on timing. Indian markets close at 3:30 PM IST, several hours before the US session opens, so there is time to review overnight developments and pre-market activity without a scheduling conflict.
