If you compare the share price of a company on the BSE and NSE, you will notice a slight difference in the pricing of the same stock on both exchanges. But, if the company is the same, why is there a price difference between the BSE and the NSE? Let us investigate!

What are BSE and NSE?
Before we get into why there is a price difference between the BSE and the NSE, let's define the terms "BSE" and "NSE."

The NSE and BSE are the two most popular stock exchanges in India, serving as a market for buying and selling Indian publicly traded companies.

The Bombay Stock Exchange (BSE) was founded in 1875 and is Asia's oldest stock exchange. It is located on Dalal Street in Mumbai, Maharashtra. Over 5,500 companies are publicly traded on the BSE.
The National Stock Exchange (NSE) is another major stock exchange in India, located in Mumbai, Maharashtra. It was founded in order to break the monopoly of the Bombay Stock Exchange in the Indian market. The NSE has over 1800 public Indian companies listed on it. When compared to the BSE, the NSE has a higher trading volume. These publicly traded stocks can now be bought and sold on either exchange. It is also possible to purchase stock on one exchange and then sell it on another.

Consider the following scenario:
Maruti Suzuki is a public company in India that is listed on both the NSE and the BSE. However, if you look at the Maruti share price on both exchanges, you will notice a slight difference in the prices. Maruti Suzuki, for example, had a last trading price (LTP) of Rs 9,167 on the BSE and Rs 9,173 on the NSE on August 2nd, 22.
