The stock market has its own language. If you are new to investing, terms like IPO, dividend, market capitalisation, EPS, and P/E ratio can be confusing at first. With these basics down, it's easier to follow the financial news, company results, and trading platforms.
You do not need to memorise every financial term before learning about the market. What matters is knowing the terms you are most likely to come across and understanding what they mean in simple terms.
This article walks you through 25 essential stock market terms, from basic ownership concepts to valuation metrics, trading tools, and market instruments.
Key Takeaways
- Stock market terms cover core areas including ownership, valuation, returns, trading mechanisms, and market movements.
- Metrics like market capitalisation, EPS, and P/E ratio help evaluate company size, profitability, and valuation.
- Volatility and liquidity describe how a security behaves and trades in the marketplace.
- Advanced trading techniques involving margin and short selling carry heightened financial risks.
- Vocabulary is only a starting point. Solid investment decisions require analysing a company's fundamentals, financial performance, and risk profile.
How Stock Exchanges Work
The stock market is a centralised marketplace where companies seeking capital connect with investors. Companies raise public funds through an Initial Public Offering (IPO), after which existing shares trade continuously on the secondary market, primarily through India's two major exchanges: the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE). Share prices fluctuate dynamically based on supply, demand, corporate earnings, and macroeconomic conditions.
