The principal elements which determine if or not a share price goes down or up really are demand and supply. Essentially, if more people wish to obtain a conversation than selling it, then the purchase price increases as the talk is far more sought (the’ ‘demand’ outstrips the ‘supply’). On the flip side, if distribution is significantly more than demand, then the cost will soon collapse.

How demand and supply affect share prices

Supply and demand impacts the allure – and, fundamentally, the purchase price – of stocks. While it may appear there are different factors in play, like the fitness of the market and business earnings, all these are just drivers of demand and supply.

This means, even in the event that you believe a stock is undervalued, the marketplace determines exactly what it’s ‘s worth. It’s exactly about the energetic between sellers and buyers.

If greater buyers proceed in the current market, the requirement develops and share prices move up – particularly when there’s limited distribution. When demand and supply are only about equal, the share price is very likely to maneuver in a narrow scope for some time, before one of those variables outweigh another.

Supply facets which affect share prices

Supply facets which affect share prices comprise company share problems, share buy backs and sellers. It’s essential to be aware that share prices should return if distribution is more than demand, when more shareholders start to promote.

Company share problems

A conversation issue is when a firm releases fresh stocks into the general public. To put it differently, as it generates stocks offered . There’s almost always a limited quantity of stocks in flow for almost any specific company, therefore if many investors wish to get a share and that the distribution is low, then the share price increases.

Share buy back

A share buy back is when a corporation buys back its shares from shareholders to decrease supply. Once this occurs, the stocks are cancelled or retained for redistribution later on. A share buy back lowers the entire quantity of stocks in flow, which might grow the share price in addition to the organization ‘s earnings per share (EPS).


Sellers would be the shareholders accountable for pushing stocks straight back in the current market, increasing the distribution. They typically market to turn a profit, once they expect that a change, or any time they think the conversation is losing an excessive amount of price. If require doesn’t match the increased supply, the price will go down. Equally, if there are more buyers than sellers, the price will rise.

Demand factors that affect share prices

Demand factors that can affect share prices include company news and performance, economic factors, industry trends, market sentiment and unexpected events such as natural disasters.

Demand gives shares value. If there is no demand for a company’s shares, they will have no value.

Expected and unexpected company news

Any news surrounding a company – expected or unexpected – can cause movement in its share price. For example, an earnings report that reveals significant profit, a new product launch, missed targets, or the death or departure of a key figure could all lead to swings in demand and share prices. Even natural disasters can cause business disruption and increase a company’s debt, meaning less demand.

Economic factors

Economic factors including interest rate changes, financial outlook and inflation all affect share prices. If the interest rate and inflation go up, and the economic outlook is poor, demand will usually decrease, and the share price is likely to come down.

Industry trends

Industry trends often determine the price of shares because companies in the same industry often perform similarly and are subject to the same pressures. So, when an industry is booming, share demand in that specific sector will often increase, pushing share prices up. It’s also possible for demand of one company’s shares to increase if a competitor is doing poorly.

Market sentiment

Market sentiment refers to the overall feeling that traders have about an asset. Understanding market sentiment can be a powerful tool for an investor. It can often be purely psychological, as investors are influenced by the mood in the markets instead of concrete news or figures. It can also be quite subjective and assumptive, but can be used to inform fundamental and technical analysis to estimate changes in share prices.

How to analyse share price changes

To analyse share price changes, you can employ fundamental and technical analysis. By using analysis as part of your trading strategy, you can predict further share price changes and find trading opportunities.

Fundamental analysis

Fundamental analysis is an in-depth method of studying a company’s financials and external factors to gauge the value of its shares. Fundamental analysis often uses various ratios to determine the value of stock and gauge price movements, such as the price-earnings ratio (P/E), relative dividend yield and return on equity (ROE).

Technical analysis

Technical analysis is a means of using historical charts to predict share price changes. Historical prices are a helpful way of predicting future prices. If traders can familiarise themselves with past patterns, they can recognise the patterns if they appear again. Though, these patterns could have formed under special circumstances, so they are not always the most reliable indicator.
