Here are some of the most common stock market terms you’ll encounter as you start your investing journey:

Dividend
A portion of a company’s profit distributed to shareholders, either in cash or additional shares.
Capital Gain
Profit made when selling a stock at a higher price than its purchase cost.
Capital Loss
The opposite of a capital gain — a loss incurred when selling a stock at a lower price than it was bought.
Blue Chip
Stocks of large, stable, and reputable companies considered relatively safe for long-term investment.
IPO (Initial Public Offering)
The first time a company offers its shares to the public, also known as going public.
IDX Composite (IHSG)

ETF (Exchange-Traded Fund)
An investment fund traded on the stock exchange, typically designed to follow the performance of a specific index.
Lot

Ask / Offer

Liquidity

EPS (Earnings Per Share)
A company’s net profit divided by its total shares outstanding — a key measure of profitability.

A ratio comparing a stock’s price to its earnings per share. A higher P/E indicates a more expensive valuation.
P/B Ratio (Price to Book Value)

Market Cap (Market Capitalization)
The total market value of a company, calculated by multiplying its share price by the number of shares outstanding.
Cut Loss
A strategy to sell a stock at a loss to prevent further decline in value.
Average Down
Buying more shares of a declining stock to lower the average purchase price.
Margin Trading
Borrowing money from a broker to buy more stocks — amplifying both potential profits and losses.
Short Selling
Selling borrowed shares with the expectation that prices will fall, allowing the trader to buy them back at a lower price.
Rights Issue
When a company issues new shares to existing shareholders, usually to raise additional capital.
Stock Split

Buyback

Insider Trading
The illegal act of trading stocks based on confidential, non-public information.
Portfolio
The collection of assets owned by an investor — such as stocks, ETFs, and bonds — diversified to manage risk.
Common Mistakes Beginners Make with Stock Terms
- Memorizing without understanding: Many beginners learn definitions but don’t know how to apply them.
- Ignoring context: Knowing what a P/E ratio is, but not how to compare it across industries.
- FOMO from buzzwords: Hearing “bull market” and buying impulsively without research.
Learning stock terms is helpful, but applying them through practice and real-world examples is what builds confidence.
