Investors often hear the phrase “price is set by supply and demand,” a concept rooted in basic economics. In the investment world, we refer to this buying force as “demand” (Demand) and the selling force as “supply” (Supply). Both are crucial for predicting price movements of assets, and those who understand this relationship well will have an advantage in making investment decisions.
What is Demand: The Buying Force Driving Price
Demand or consumer demand is the desire to purchase goods, services, or financial assets at various price levels. When plotted on a graph, it produces a demand curve showing the relationship between price and the quantity buyers want.
The key principle in understanding demand is the Law of Demand—the inverse relationship between price and quantity demanded, which means:
When price decreases → demand increases
When price increases → demand decreases
This phenomenon results from two effects: Income Effect (When prices fall, our money “value” actually increases) and Substitution Effect (Comparing goods with alternatives).
###Factors Affecting Demand
Buyers’ income levels
Prices of substitute or complementary goods
Consumer tastes and preferences
Number of buyers in the market
Expectations of future prices
External factors such as seasons, government policies, technology, and consumer confidence
In financial markets, demand is influenced by liquidity in the system, interest rates, and investor confidence in the future economy.
Supply: The Limited Selling Force
Supply (Supply) is the willingness to sell goods, services, or assets at various price levels. When plotted, it produces a supply curve showing the quantity sellers are willing to offer at different prices.
The Law of Supply describes a direct relationship—not inverse:
When price increases → quantity supplied increases (Sellers are more motivated)
When price decreases → quantity supplied decreases
(Factors Affecting Supply
Production and operational costs
Prices of alternative goods that can be produced
Number of competitors in the market
Technology levels
Climate and natural factors
Tax policies and price controls
Access to funding sources
In stock markets, supply is affected by corporate decisions to raise capital, buy back shares, stock exchange regulations, and new company listings.
Equilibrium Point: Where Demand and Supply Meet
Most importantly: Actual market prices occur at the equilibrium point )Equilibrium###—the point where demand and supply curves intersect.
At this point:
The quantity buyers want equals the quantity sellers are willing to sell
Price and quantity tend to stabilize until new factors emerge
When prices are above equilibrium:
Excess supply = surplus → downward pressure to return to equilibrium
When prices are below equilibrium:
Excess demand = shortage → upward pressure to return to equilibrium
Demand, Supply, and Stock Price Changes
Stocks are commodities like others, so the demand-supply principle can be applied to analyze stock prices. Price changes result from shifts in buying and selling forces.
( Fundamental Analysis
When news about a company is released:
Good news → Demand )Demand### increases → Buyers are willing to pay higher prices → Stock prices rise
Bad news → Supply (Supply) increases → Sellers are willing to lower prices → Stock prices fall
( Technical Analysis
Traders use technical tools to measure buying and selling strength:
1) Price Action and Candlesticks
Green candlestick ###Close > Open) = Strong demand
Red candlestick (Close < Open) = Strong supply
Doji = Demand and supply are balanced
2( Market Trend)
Prices making new highs = Demand remains strong
Prices making new lows = Supply remains strong
Price oscillating within a range = Balance between demand and supply
3) Support & Resistance(
Support = Level where demand )Buyers waiting to buy) is high enough to prevent price from falling further
Resistance = Level where supply (Sellers waiting to sell) is high enough to prevent price from rising further
Demand Supply Zone: Trading Technique to Catch the Moment
The Demand Supply Zone (DSZ) technique uses demand and supply principles to identify trading opportunities by spotting points where price loses balance and moves out of a range.
( Reversal Patterns)
Demand Zone Drop Base Rally (DBR) - Uptrend Reversal
IPOs = New securities entering the market = Increased supply
Regulations
Silent Periods prevent major shareholders from selling after IPO = Supply control
Summary: Why You Should Understand Demand and Supply
Demand and Supply are not just economic terms; they are the actual mechanisms driving prices every day.
When you understand:
Why stock prices go up (More demand than supply)
Why prices fall (More supply than demand)
The points where these forces diverge
You can predict price movements more accurately than others.
Practicing through real observations, analyzing price charts, and keeping trading logs will help you better grasp the market’s nuances.
