What Causes Stock Prices To Rise And Fall
Stock prices move constantly — even by the second. But why they move isn’t random. Prices change based on supply and demand, which are influenced by many different factors.
At its core:
Stock prices rise when more people want to buy than sell.
Stock prices fall when more people want to sell than buy.
But what makes investors decide to buy or sell? Let’s break it down.
The Main Factors That Influence Stock Prices
1. Company Performance (Earnings Reports)
When a company announces strong profits, growing revenue, or beats market expectations, investors get excited — and demand for the stock increases.
Good news → More buyers → Price goes up
Poor results or missed forecasts → More sellers → Price goes down
2. Future Expectations
Sometimes, the future outlook matters more than current results. If investors believe the company will grow rapidly in the future, they may pay a high price today.
-
Launching a new product
-
Entering a new market
-
Securing a big contract
All of these can drive the price higher.
3. Industry and Sector Trends
Even if a company is doing well, it can be affected by the overall performance of its industry.
Example:
If oil prices fall, oil company stocks might drop — even if they’re profitable.
4. Economic Conditions
The broader economy plays a big role in stock prices:
-
Low interest rates make stocks more attractive (money is cheaper to borrow)
-
High inflation can hurt profits and reduce buying power
-
Recession fears or economic slowdowns often cause prices to drop
5. Market Sentiment and Investor Psychology
Emotions drive markets more than most people realise.
-
Fear (bad news, economic panic) → Selling pressure
-
Greed (bull markets, hype) → Buying frenzy
-
Sometimes prices rise or fall based on rumors, headlines, or social media buzz.
6. Geopolitical Events and Global News
Wars, pandemics, elections, and trade disputes can all affect markets — especially multinational companies.
Example:
Tensions between countries can affect oil companies, tech stocks, or exporters.
7. Supply and Demand for Shares
If more people want to buy a stock than sell it, the price must rise to match supply with demand.
If more people are selling, the price falls until buyers step in.
8. Interest Rates and Central Bank Policies
When central banks (like the Federal Reserve or Reserve Bank of Australia) raise rates:
-
Borrowing becomes more expensive
-
Consumer spending may drop
-
Company profits can shrink
This often causes stock prices to fall.
Lower rates usually have the opposite effect.
9. Dividends and Share Buybacks
-
Companies that increase dividends or buy back their own shares often see a rise in stock price.
-
This shows confidence and rewards shareholders.
10. Technical Factors (Trading Volume, Momentum)
Some short-term traders buy or sell based on chart patterns, volume spikes, or price momentum — which can temporarily drive prices up or down even without big news.
Summary
Stock prices are driven by what people believe a company is worth now and in the future.
That belief is shaped by real business performance, news, emotions, the economy, and global events.
In the short term, markets can be volatile and unpredictable — but over the long term, strong companies tend to rise in value as they grow and deliver results.
