See why stock prices or various assets are constantly changing. The main reason comes from a very simple principle: supply and demand.

The truth is, the factors that determine supply and demand are many and not just about the price itself. Many people often think that high prices mean they don't want to buy, and low prices mean they want to buy. But in reality, there are many other factors involved.

Let's start with the demand side first. When the economy is growing well, people have more leftover money. They look for ways to invest so their money can work for them. The demand to buy stocks therefore increases. But if the economy is in a downturn, people become cautious and reduce their investments. Interest rates also play a role. When interest rates are low, investors don't want to keep their money idle; they seek returns in the stock market instead. So, demand to buy stocks surges.

Another important factor is market confidence. If the news is good, people are eager to buy. If the news is bad, everyone wants to sell. Expectations about the future of companies or the economy are very powerful.

On the supply side, it relates to the decisions made by companies. If a company decides to buy back its shares, the supply decreases, and the price tends to go up. If a company issues new shares through a capital increase, the supply increases, and the price may be pushed down. Additionally, IPOs of new companies increase the number of securities in the market, and regulations or restrictions also affect supply.

What’s interesting here is to observe what factors influence supply and demand. In summary, it’s not just the price figures. Macroeconomic factors such as economic growth, inflation, and interest rates all play a role. Investor confidence is also a driving force. Company policies, market news, and even global events like wars all determine the direction of prices.

There is a balance called Equilibrium, which is the point where demand equals supply. At this point, prices are stable. But in reality, the market never stops. When new factors come in, the equilibrium shifts, and prices move accordingly.

For traders or investors, understanding this helps a lot. If you know that supply is decreasing and demand remains strong, you can expect prices to rise. Conversely, if demand weakens due to bad news and supply increases, prices will be pushed down.

Some traders use a technique called Demand Supply Zone to time their buy and sell points. They observe whether prices are moving strongly in one direction and try to enter when there’s a pause. If prices surge and then pause within a range, breaking above that range could mean a continued rally. If prices drop sharply, pause, and then break below, it could continue downward. But this requires observation and experience.

The most important thing is not to think that stock prices move randomly. There are reasons behind the movements. The factors that determine supply and demand are complex and interconnected. But if you understand these basic principles, you will be better at reading the market and making smarter investment decisions.
