There is a complex mechanism for every single transaction. There are factors that decide what you pay for your part in the stock market. So, what are the factors that drive these numbers up and down? Keep on reading to find out how stock prices are determined and make smarter financial decisions.

What is a Stock Price and How is it Calculated?

A stock price or share price is the cost of a single share in a company listed on the stock market. The stock price is not fixed. It tends to fluctuate with the American conditions, whether the company is performing or not.

A stock price starts with an initial public offering (IPO). The price will be agreed upon between the company and investment bankers. The final number will be determined based on the valuation and perceived demand for the company’s stock.

For example, if you see that the price of Apple is $150 per share, it is the price at which the buyers and sellers agreed at the particular time. Once the IPO is complete, the company’s stock price will fluctuate when buyers and sellers exchange money for share ownership.

How are Stock Prices Determined?

Stock Prices follow patterns, trends, and reactions from the buyers and sellers in the market. Let us break down the sectors involved in the process:

Buyers and Sellers

The supply and demand determine the price of a stock. If more people want to buy a stock than sell it, then the price will increase. On the other hand, if more wpeople ant to sell than buy the stock, then the price will fall.

Market Makers

A market maker is any person or firm who provide liquidity and ensures that buyers and sellers are always available so as to stabilize the prices and maintain the functioning of the market.

Stock Exchanges

NASDAQ and other exchanges help in stock trading. These platforms don't fix the price of the stocks directly. Still, they make rules and regularye sto ensure that the trading practices are fair and have transparency.

What Factors Determine the Stock Price of A Company?

As a new investor, you might be keeping tabs on how company share prices rise and fall all day. After all, share prices ultimately determine the returns of your investments. But what are the factors that cause your stock prices to rise and fall so frequently in the first place? Here, we have listed them below:

Company’s Performance

A company’s own performance impacts its share price. Investors will look at your quarterly results, profit growth, revenue, new projects, and your brand’s long-term plans. If your company shows good profits, then the stock prices will increase. When you face loss, the price will drop. For instance, companies like TCS and HDFC bank shows good results. Their stock prices rise on the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE)

Global Events

The Indian stock market is connected to the global economy. Events in the USA, Europe, or even the Middle East can affect stock prices. Some examples of global factors include crude oil prices, US Federal Reserve interest rate decisions, international conflicts, and global recession news. For instance, most of the crude oil products in India are imported. So, if the global price rises, the Indian stock market will react adversely, and most stock prices will fall.

Economic Conditions

The state of the national economy affects the stock prices. When the economy is growing, more businesses will make profits, which will increase job opportunities, and people tend to spend more. As a result, the stock price will rise with confidence. For example, when the RBI decreases the interest rates, borrowing loans will become cheap for people and companies. It will enable companies to expand their growth with less expenditure on interest. Similarly, individuals can get loans at better prices.

Government Policies and Regulations

The government's actions have a strong impact on stock market prices. New schemes, changes in taxation, or reforms in industries like banking can affect the investor preferences. If the government announces a policy that helps the banking sector, then the investor will be more likely to purchase shares in the sector. As a result, banks will see a price increase in their shares.

Market Sentiment

Stock prices may not rise or fall based on how the investors feel. This phenomenon is known as market sentiment. If investors feel positive and hopeful about a stock, the price will rise. If they don't feel confident, then the stock price will go down. Such market sentiment is usually marked by news, social media discussions, expert opinions, and overall market share.

Foreign Investor Activity

Foreign Investors play an important role in the stock market. When they invest big, the stock price will rise. On the other hand, when they begin to sell or pull out money, the market often goes down. It is one of the primary reasons why the stock market witnesses sudden movements.

How to Keep up with the Stock Prices?

The stock price fluctuates according to market conditions. It rises when the company does well and falls when it fails to meet expectations. To keep up with the constant changes, follow the tips below:

Research

The key to successful stock market investment is research. Think about the company you are interested in and what it makes. What part of the world do they operate in? How big are they? Is their market volatile? The answer to these questions will help you make a smarter investment.
