I just realized that many people still don't truly understand supply and demand, even though it's the fundamental principle driving the prices of everything—whether stocks, energy, or even digital assets. Let me explain it simply.

Actually, it's not that complicated. Demand is the desire to buy, and supply is the desire to sell. Market prices are set at the equilibrium point where the two lines intersect.

Let's look at demand first. When prices go down, the desire to buy increases (because it's cheaper), and when prices go up, the desire to buy decreases (because it's more expensive). This is a basic rule. The reasons are twofold: when prices fall, your money becomes more valuable (Income Effect), and this product appears more attractive compared to similar products (Substitution Effect).

As for supply, it's the opposite. When prices rise, sellers want to offer more, and when prices fall, they don't want to sell. This depends on production costs, competition, technology, and future price expectations.

What's interesting is that this equilibrium isn't fixed. It changes based on various factors. For example, in March, when the Strait of Hormuz was closed due to the Iran war situation, about 20% of the world's crude oil passing through that point disappeared from the market immediately. This was a sharp reduction in supply, while demand remained the same, causing prices to spike due to scarcity.

In financial markets, it's similar. The demand for stocks depends on macroeconomic factors, interest rates, and investor confidence. Supply depends on company decisions (like buybacks or issuing new shares) and new listings.

If you're a trader, understanding this is very useful. For example, when prices rise rapidly and then consolidate (base), it indicates demand is slowing down while supply is entering. When good news comes, demand picks up again, and prices break out of the range.

Conversely, when prices fall and consolidate, it shows selling pressure is easing and buying interest is coming in. When news hits, selling pressure intensifies, and prices break below the range.

In summary, supply and demand are not just economic theories—they are the real forces driving markets. Deeply understanding them will help you analyze prices more accurately, whether you're trading stocks or other assets.
