Background
The share price of a company reflects its current market valuation as determined by ongoing trading activities. Representing the price at which a share can be traded, share prices fluctuate continuously during trading hours due to supply and demand dynamics.
Historical Context
Historically, the concept of share price emerged with the inception of stock markets during the early modern period. Stock exchanges facilitated the trading of shares and allowed companies to raise capital from dispersed sellers.
Definitions and Concepts
A share price is not a single fixed figure. It commonly comprises the following components:
- Offer Price: The price at which market-makers are willing to sell shares.
- Bid Price: The price at which market-makers are willing to buy shares.
- Mid-Market Price: The average of the offer and bid prices.
In instances where shares are infrequently traded, the reported price might be the last transaction price, which may not be indicative of current trading terms.
Major Analytical Frameworks
Classical Economics
Classical economics generally assumes market efficiency where share prices are determined purely by supply and demand forces.
Neoclassical Economics
Neoclassical models emphasize rational behavior and equilibrium in pricing where share prices reflect the present value of expected future dividends.
Keynesian Economics
In Keynesian economics, share prices can be influenced by market psychology and investor sentiment, often leading to short-term speculative bubbles.
Marxian Economics
From a Marxian perspective, share prices can reflect the contradictory nature of capital, where financial markets are prone to crises as part of broader capitalist dynamics.
Institutional Economics
This view focuses on the role of institutional structures, market rules, and regulatory frameworks in shaping share prices.
Behavioral Economics
Behavioral economics studies how psychological factors and cognitive biases affect investor decisions and hence share price movements.
Post-Keynesian Economics
Post-Keynesian frameworks build upon Keynes’ idea of uncertainty and non-equilibrium processes guiding share price formations.
Austrian Economics
Austrian economists emphasize individual preferences, market processes, and the role of entrepreneurial discovery in price formation.
Development Economics
Development economics may look into how stock market mechanisms and financial market integration influence share prices in developing economies.
Monetarism
Monetarism views the impact of money supply changes and monetary policy adjustments on stock market prices, including share prices.
Comparative Analysis
Each analytical framework sheds light on different facets of how share prices are determined, traded, and perceived, emphasizing the multi-faceted nature of price formation in financial markets.
Case Studies
Case studies often involve examining specific historical stock market events, such as the 2008 financial crisis, to understand how various factors influenced share prices.
