Every security traded in a financial market generates a stream of price and trading information. Whether analyzing a share, bond, ETF, or other financial instrument, investors rely on market prices to assess value, monitor performance, and evaluate trading activity.
Understanding how to interpret market price information is an essential skill for investors. While a price alone does not provide a complete picture of an investment, it serves as the starting point for most forms of market analysis.

Understanding Market Prices
The market price of a security represents the most recent price at which a transaction has taken place between a buyer and a seller. This is often displayed as the Last Traded Price and is one of the most commonly viewed data points on financial platforms.
Market prices change as investors react to new information, company announcements, economic developments, and broader market conditions. As a result, prices fluctuate throughout the trading day based on supply and demand.
While market prices provide valuable information, they should be considered alongside other data such as trading volume, company fundamentals, and market conditions.
Key Definition
Last Traded Price: The most recent price at which a security was bought or sold.
Bid and Ask Prices
At any given time, buyers and sellers may be willing to transact at different prices.
The Bid Price is the highest price a buyer is currently willing to pay for security.
The Ask Price is the lowest price a seller is willing to accept.
A trade occurs when a buyer and seller agree on a price.
The difference between the bid and ask prices is known as the Bid-Ask Spread.
In general, securities with higher trading activity tend to have narrower spreads, while less actively traded securities may have wider spreads.
Key Definitions
Bid Price: The highest price a buyer is willing to pay.
Ask Price: The lowest price a seller is willing to accept.
Bid-Ask Spread: The difference between the bid and ask prices.
Measuring Daily Price Performance
Investors often monitor how prices change during a trading session.
Two commonly displayed measures are:
Day Change
The difference between the current price and the previous closing price.
Percentage Change
The percentage increases or decreases relative to the previous closing price.
Percentage change allows investors to compare performance across securities regardless of their absolute price levels.
Percentage Change Formula
Percentage Change= Current Price- Previous price/pervious Price* 100
Positive changes indicate price appreciation, while negative changes indicate a decline in value.
Understanding Open, High, Low and Close (OHLC)
OHLC data summarises how a security traded during a specific period and forms the basis of many price charts and technical analysis tools.
| Metric | Description |
|---|---|
| Open | First traded price of the session |
| High | Highest traded price of the session |
| Low | Lowest traded price of the session |
| Close | Final traded price of the session |
Together, these figures provide a snapshot of market activity and investor sentiment during a trading period.
OHLC data is widely used in charting and technical analysis because it provides more information than a single price point.
Using Market Prices in Investment Analysis
Market prices provide valuable information about how investors are valuing security at a particular moment in time. However, price data should not be viewed in isolation.
Many investors combine market prices with:
- Trading volume
- Financial statements
- Company announcements
- Valuation ratios
- Economic data
This broader approach helps investors understand not only where security is trading, but also why it may be trading at that level.
Understanding market prices is the first step towards interpreting more advanced market data and conducting meaningful investment analysis.
