How are stock prices determined?

Stock prices are determined by a complex interplay of factors, reflecting investors' constantly evolving perceptions, expectations, and actions in the financial markets. Understanding how stock prices are determined requires delving into the fundamental principles of supply and demand dynamics, market sentiment, company performance, economic indicators, and various other factors. 

Primarily, the per-share price of a stock is influenced by the principles of supply and demand. When demand exceeds the available supply of shares, the stock price tends to increase. Conversely, when supply surpasses demand, the stock price generally decreases.

Setting stock prices

Imagine investors eagerly seeking shares of ABCD Inc., an energy company. On Monday, the stock is valued at Rs. 35 per share. However, the following day, a Dalal Street analyst released a favorable report regarding the energy sector's prospects. This optimistic assessment sparks increased demand for ABCD stock, elevating its price to Rs. 40 per share. Consequently, within a single day, the stock price experiences a notable 14% surge.

On the contrary, consider RXYZ Co., as a fictitious healthcare company. At the start of the week, its stock may be valued at Rs. 45 per share. However, on the subsequent day, a Dalal Street analyst releases negative news regarding the healthcare sector's future. This prompts certain investors to dump their shares of RXYZ, resulting in a decline in stock price to Rs. 40 per share. This sharp downturn reflects a one-day decrease of 11% in the stock's value.

What factors affect the share prices of listed companies?

Company activity can significantly impact share price through various means. Positive activities, such as strong earnings reports, innovative product launches, strategic acquisitions, or expansion into new markets, often lead to increased investor confidence and demand for the company's stock, consequently driving its price higher. 

Conversely, negative developments, such as poor financial performance, management scandals, regulatory issues, or product recalls, can erode investor trust and prompt selling pressure, resulting in a decline in share price.

Economic Conditions

Favorable economic conditions, robust GDP growth, low unemployment, stable inflation rates, and monetary policies, typically instill confidence in investors, fostering optimism about corporate earnings and prospects. Consequently, stock prices tend to rise as demand increases. 

Conversely, during periods of economic uncertainty or downturns marked by recessionary pressures, high unemployment, inflationary concerns, or tightening monetary policies, investor confidence fades, leading to volatility and downward pressure on share prices. 


Inflation, characterized by a general rise in the prices of goods and services, diminishes the purchasing power of both businesses and consumers. 

Consequently, fluctuations in inflation rates can significantly impact investor sentiment and stock market activity. When inflationary pressures intensify, investors may adopt a cautious stance, leading to divestment from stocks. 

On the contrary, a moderation in inflationary trends typically fosters optimism among investors, urging them towards stock-buying activity. In other words, the trajectory of inflation exerts a distinct influence on stock prices, shaping market dynamics accordingly.

Interest rates

Interest rates can simply impact share prices: when interest rates go up, it becomes more expensive for companies to borrow money. This means they might have less money to invest in growing their business, which can slow down their growth and lower their share prices. 

Moreover, higher interest rates can make bonds and other fixed-income investments more attractive compared to stocks, leading some investors to sell their stocks and buy these safer investments instead. 

Conversely, when interest rates go down, borrowing becomes cheaper for companies, which can stimulate business growth and increase share prices. Lower interest rates also make stocks more attractive relative to bonds, potentially leading to increased demand for stocks and higher prices.

Consumer Spending

Consumer spending plays a crucial role in influencing share prices. When consumers spend more money buying products and services, companies tend to earn higher profits, which can lead to higher stock prices. 

Conversely, if consumer spending slows down, companies may experience lower revenues and profits, causing investor concerns and potentially leading to a decline in share prices. Strong consumer spending often correlates with positive stock market performance, while weak consumer spending can have the opposite effect.

World Events

World events can impact share prices because they can affect investor confidence and perceptions of risk. Positive events like economic growth or peace agreements can boost investor optimism, leading to higher share prices as people anticipate increased profits. 

On the other hand, negative events such as wars, natural disasters, or economic downturns can create uncertainty and fear among investors, causing them to sell stocks and driving share prices down. 

Eventually, world events can shape investor sentiment and influence their decisions to buy or sell stocks, impacting share prices accordingly.

Major Investors

Institutional investors such as mutual funds and hedge funds, can significantly impact share prices due to their substantial buying or selling power. When these investors buy a large amount of shares in a company, it can drive up demand and push share prices higher. 

Equally, if major investors sell off their holdings, it can lead to an oversupply of shares in the market, causing prices to decline. Essentially, the actions of major investors can influence market sentiment and directly affect the supply and demand dynamics of a stock, thereby impacting its price.

Why do stock prices change every second?

Stock prices change every second because they are constantly being influenced by various factors such as investor sentiment, economic data releases, company news, and global events. Buyers and sellers continuously trade stocks based on their perceptions of a company's value and prospects. 

As new information becomes available and market conditions evolve, the balance between supply and demand for a stock shifts, causing its price to fluctuate in real time. Essentially, the dynamic nature of the stock market means that prices can change rapidly as traders react to changing circumstances.
