When it comes to stock price forecasting, most traders tend to focus on technical and fundamental data. However, there is a fundamental principle that is more important: understanding the buying and selling forces that cause price movements, known as supply and demand. For those just starting in the investment world, this concept may sound complicated, but a proper understanding of how supply works will help you make better investment decisions.
Understanding Supply and Demand from the Basics
In economics, supply refers to the willingness to sell a product at various price levels, while demand is the willingness to buy. The relationship between these two forces determines the market equilibrium price.
Demand (Demand) reflects that when prices fall, consumers want to buy more. Conversely, when prices rise, demand decreases. In other words, buyers value the product differently—some are willing to pay higher prices, others want lower prices.
Supply works in the opposite way. When prices increase, sellers want to offer more because profits are higher. When prices decrease, sellers tend to hold back on selling. The point where the demand and supply curves intersect is the equilibrium point, where price and volume tend to stabilize.
Drivers of Supply in the Financial Markets
In the stock market, where does the supply of shares come from? It originates from company decisions, investor forced sales, and market policies.
Company Policies: When a company decides to raise capital or issue new shares, the supply of shares in the market increases. Conversely, share buybacks (Buyback) reduce supply, directly affecting the price.
Major Shareholders: After an IPO or during the Silent Period, large investors may sell shares, increasing supply.
Market Liquidity: When the financial system has abundant cash, investments flow more into stocks, increasing demand. This can lead to more available buyers, effectively increasing supply at the same time.
Market Expectations: When investors anticipate good earnings, the company’s “door” opens wider to buyers. Demand increases, and existing supply may decrease as more investors want to buy.
How Supply and Demand Rules Affect Stock Prices
Suppose you’re a trader looking at the candlestick chart of ABC stock. The price just dropped sharply—a big red candle. What does this indicate?
Strong Selling: Many sellers want to offload shares at lower prices, pushing the price down—supply exceeds demand.
When this happens, the price often stops falling at a certain level because:
Buyers start to think, “This is a good price to buy,” and step in.
Sellers begin to hold back, reluctant to sell cheaper.
The price stabilizes at a new equilibrium.
This creates a “Support” zone—where demand (buying pressure) is strong.
Similarly, when a large green candle appears, and the price surges upward, it indicates excess demand—many buyers willing to pay higher prices. When the price hits a “Resistance” zone, sellers step in, slowing the rise and establishing a new balance.
Using Demand and Supply Zones in Trading
Professional traders use this concept through Demand Supply Zones—identifying points where supply is heavy (strong selling) or demand is strong (heavy buying) to enter trades.
Scenario 1: Reversal (Reversal)
The price just dropped sharply (Drop), indicating excess supply. Then it consolidates (Base), moving sideways for a while. When buying interest returns—perhaps due to good news—the price breaks out of the consolidation (Rally). This is a breakout entry point.
This technique is called DBR (Drop-Base-Rally)—after excess supply, the market rebalances and reverses.
Scenario 2: Continuation (Continuation)
When the price moves up, showing strong demand, then pulls back, but the buying pressure resumes and pushes the price higher again (Rally-Base-Rally or RBR)—a signal for traders to add positions.
Similarly, a downtrend can be DBD (Drop-Base-Drop)—excess supply driving prices lower.
Factors Affecting Demand and Supply
Demand Side:
Interest rates: Low interest rates → more stock investments
Production costs: High costs → less willingness to sell
Competition: More competitors → increased selling pressure
Earnings: Good performance → reduced supply
Real Trading Example
Suppose XYZ stock drops from 100 to 85 in a few days (Drop)—excess supply, many sellers.
The price halts there because:
Buyers see the low price and step in.
Sellers hold back, not wanting to sell too cheaply.
The price fluctuates between 83-87 for about 5-7 days (Base).
Then, good news comes out, and the price jumps above 90 (Rally)—a buy signal for traders, even if it involves a short-term loss, because the trend has shifted.
The Importance of Understanding Supply in Investing
Whether you use fundamental or technical analysis, understanding demand and supply is what makes your strategies work.
Fundamental: Company issues cause demand to decrease (Demand decreases), leading to lower prices.
Technical: A large red candle (excess supply) indicates price decline.
Both perspectives describe the same thing—who has the stronger force.
Therefore, what you should do is:
Observe candlesticks: Large green = strong demand; large red = strong supply.
Identify support and resistance levels: Where demand/supply is waiting to intersect.
Wait for price to test these zones: Look for gentle candles (Doji) before reversal.
Enter on breakout: When demand or supply wins.
Summary
Supply is not as mysterious or complicated as many think. It’s about observing selling versus buying forces. Every trade in the market results from an imbalance between those wanting to sell and those wanting to buy.
When you understand that:
Strong supply = opportunity to buy (price may reverse upward)
Strong demand = warning that (price may reverse downward)
Equilibrium = waiting zone (unclear timing)
Your trading and investment decisions will become more rational. Even if you lack extensive experience, this basic understanding will help protect your capital longer than your first few trades.
