## Why Do Stock Markets Move? The Demand and Supply Factors Every Investor Should Know

If you've ever wondered why stock prices sometimes keep rising and other times plummet sharply, the main reason comes down to what is called **demand and supply**, which is not just a theory from economics textbooks but a real force flowing through the financial markets every day.

## What Are Demand and Supply? An Easy Explanation

Think of it like this: In the market, there are two sides — **Buyers (Demand)** who want to own shares and are willing to pay, and **Sellers (Supply)** who hold shares and want to sell. When buyers and sellers meet, the stock price is set at the equilibrium point.

To clarify:
- **Demand** = Desire to buy (People want shares → Price goes up)
- **Supply** = Desire to sell (Many want to sell → Price goes down)

## The Basic Laws of the Market

The key is understanding that:

**High Price = Strong Demand** Investors think the stock is worth buying and want to get it, so sellers hold back, keeping the price high.

**Low Price = Strong Supply** Many want to sell, making the price drop. When investors see the price is low, they buy more, pushing the price back up.

This is driven by two fundamental factors:
- **Income Effect** - When prices fall, people feel their money has more value and are more willing to buy.
- **Substitution Effect** - When this stock's price drops compared to others, it becomes more attractive, so investors switch to buying this one.

## How Financial Markets Differ from Normal Markets

If demand and supply are normal, why is the stock market different? First, the factors driving demand in the stock market are more complex:

**Demand Drivers:**
- Macroeconomic conditions (Low interest rates → Investors prefer stocks over bonds)
- System liquidity (More cash → More investment capacity)
- Investor confidence (Good news → Buy more, Bad news → Stop buying)

**Supply Drivers:**
- Company policies (Share buybacks → Reduce supply, Capital increases → Increase supply)
- IPOs of new companies (Adding securities to the market)
- Regulations and restrictions (e.g., Silent Periods prohibiting large share sales)

## Why Is the "Equilibrium Point" Important?

When the demand and supply lines intersect, that point is called the **equilibrium point**. The price and volume at this point tend to stay stable because:

- If the price rises above equilibrium → More sellers produce, fewer buyers → Excess inventory → Price drops back to equilibrium.
- If the price falls below equilibrium → More buyers, fewer sellers → Shortage → Price rises back to equilibrium.

Since markets have a natural tendency to return to equilibrium, knowing where this point is allows you to predict where prices might go.

## Applying Demand and Supply Principles to Stock Trading

This is where regular traders differ from long-term investors.

### Fundamental Analysis

Here, we look not just at stock prices but at the **market value (Market Cap)** of the company. If the company has growth factors (improved performance, good management), there will be many buyers, creating strong demand and pushing prices up. Conversely, bad news will lead to more sellers, increased supply, and falling prices.

### Technical Analysis

When it comes to technical analysis, there are easier-to-understand methods:

**1) Candlestick Charts (Candle Stick)**
- Green = Close > Open = Buying pressure (Demand)
- Red = Close < Open = Selling pressure (Supply)
- Doji = Close = Open = Both sides are evenly matched

**2) Market Trends (Trend)**
- Higher highs = Demand remains strong → Uptrend
- Lower lows = Supply remains strong → Downtrend
- Sideways movement = Both sides are balanced → Wait for a breakout

**3) Support & Resistance (Support & Resistance)**
- Support = Price level where buyers tend to step in (Price won't go lower)
- Resistance = Price level where sellers tend to step in (Price won't go higher)

## Practical Technique: Demand Supply Zone

Professional traders often use **Demand Supply Zones**, focusing on two main types:

### Reversal (Reversal)

**DBR (Drop Base Rally) - Uptrend**
- Price drops rapidly (Drop) → consolidates to form a base (Base) → then rallies up (Rally)
- Buy signals at breakout points above, with Stop Loss set

**RBD (Rally Base Drop) - Downtrend**
- Price rises rapidly (Rally) → consolidates (Base) → then drops (Drop)
- Sell signals at breakout points below, with Stop Loss set

### Continuation (Trend)

**RBR (Rally Base Rally) - Continuing Uptrend**
- Price rises → short pause → continues upward
- View: Demand is still strong → buy on breakout of the range

**DBD (Drop Base Drop) - Continuing Downtrend**
- Price drops → short pause → continues downward
- View: Supply remains strong → sell on breakout of the range

## Simple Truth

**Demand and supply** are the engines driving the entire market. Whether you want to do fundamental or technical analysis, investors who understand when demand is strong, supply is strong, or both are balanced can make more effective buy and sell decisions.

Tip: The theory is useful, but practicing with real market prices is what will give you a clear picture and turn you into an effective trader.
