What Makes Stock Prices Go Up And Down?

Stock prices go up and down primarily because of supply and demand. Billions of shares of stock are bought and sold each day, and the degree to which there are more buyers than sellers ultimately sets stock prices.

So while supply and demand laws are the fundamental answer to the question, why would more people be inclined to buy a stock, or sell a stock? This is where the nuance of analysis starts to come up and we can dive into a few key factors.

Earnings and Profitability

One of the primary drivers of stock prices over longer time horizons is the company’s earnings and profitability. Positive financial performance, such as increasing revenues and profits, often leads to higher stock prices. Investors and traders are naturally drawn to companies that demonstrate consistent growth or the potential for future profitability. Strong earnings reports can attract more buyers, increasing demand for the stock and consequently driving its price up. When a weak earnings report comes out, the buyers disappear and sellers are likely to push prices lower. Think less demand, more supply.

Market Sentiment and Investor Perception

Stock prices can also be influenced by market sentiment and investor’s perception of future profitability. Positive news about a company, such as successful product launches or strategic partnerships, can act as a positive catalyst, leading to increased buying pressure. On the other hand, negative news or public perception can result in selling pressure and a decrease in stock prices. Examples would be lawsuits, failed trials in the biotech space, or the collapse of a tentative buyout deal. The main idea is that catalysts reveal some previously unknown information, and as traders act on that information buying or selling to reflect their belief of what has happened.

Interest Rates and Economic Conditions

Interest rates and broader economic conditions can impact stock prices. Lower interest rates can encourage borrowing and spending, stimulating economic growth and potentially benefiting companies’ earnings. This is particularly true in the tech industry which relies on borrowing to deliver on growth and the potential of higher returns in the future. As a result, stocks may experience upward momentum during periods of accommodative monetary policy. On the opposite side of the spectrum, higher interest rates could lead to reduced borrowing and spending, potentially impacting corporate profits and causing stock prices to decline.

Technical Patterns

In the world of short term trading, technical analysis and the anticipation of a chart pattern working or not working can also cause stock prices to move. If lots of traders are all looking at a head and shoulders pattern, which would signify a bearish reversal, it’s possible that there suddenly becomes more selling pressure because of the pattern, thus pushing prices lower. It sounds like a self fulfilling prophecy, and to some degree it is, but it speaks to perception, and how supply and demand are all that matter. If the perception of an outcome causes traders to act, that alone is enough to cause an imbalance in supply and demand.

Conclusion

At the end of the day the stock prices are driven by supply and demand. But multiple different factors work in tandem to influence stock price movements. Earnings and profitability, market sentiment, interest rates, economic conditions, and company performance are all interconnected elements that can cause stocks to go up or down. Successful investors and traders are those who carefully evaluate these factors to capitalize on opportunities in the markets.
