Glossary of Core Securities and Investing Terms

Review core securities terms used throughout introductory FINRA-style study, including trading, products, portfolio concepts, and regulatory language.

This glossary is a study aid for the terms that appear repeatedly across introductory securities lessons. It is not meant to replace the deeper chapters. It is meant to help a student quickly confirm what a term means, how it is used, and which similar terms are commonly confused on exams.

The strongest exam use of a glossary is active, not passive. When a question includes a word such as liquidity, NAV, underwriting, or yield, the student should know more than a short definition. The student should recognize what the term implies about risk, pricing, timing, or investor protection.

How to Use This Glossary

Use this page when you need a quick recall tool. If a term is tied to a larger chapter topic, go back to that chapter after reviewing the definition here. Exams rarely test vocabulary in isolation. They usually test whether you can apply the term correctly in a fact pattern.

Market and Trading Terms

Ask Price: The lowest price at which a seller is willing to sell a security. It is paired with the bid price.

Auction Market: A market in which buyers and sellers submit competing bids and offers. The exchange matches interest based on price and order priority.

Bid Price: The highest price a buyer is willing to pay for a security.

Liquidity: The ease with which an investment can be bought or sold near its current market value. Highly liquid securities are generally easier to trade without a large price concession.

Over-the-Counter (OTC): A decentralized market in which securities trade through dealer networks rather than on a centralized exchange.

Ticker Symbol: The abbreviated identifier used to reference a publicly traded security in the market.

Equity, Debt, and Fund Terms

Bond: A debt security representing money lent by an investor to an issuer. The issuer promises repayment of principal at maturity and usually periodic interest.

Common Stock: An equity security representing ownership in a corporation. Common shareholders generally have voting rights and a residual claim on assets after creditors and preferred shareholders.

Coupon Rate: The stated interest rate on a bond, usually expressed as a percentage of par value.

Exchange-Traded Fund (ETF): A pooled investment vehicle that trades intraday on an exchange, often tracking an index, sector, or strategy.

Initial Public Offering (IPO): The first public sale of stock by a company moving from private ownership into the public market.

Maturity Date: The date on which a bond’s principal is due to be repaid.

Mutual Fund: An investment company that pools investor money and prices its shares based on end-of-day net asset value.

Net Asset Value (NAV): The per-share value of a fund’s assets minus liabilities. Open-end mutual funds transact at NAV, not at continuously negotiated market prices.

Option: A derivative contract granting the right, but not the obligation, to buy or sell an underlying asset at a stated price before or at expiration.

Par Value: The face amount of a bond that is repaid at maturity, commonly $1,000 for corporate and municipal bonds in exam questions.

Preferred Stock: A class of stock that typically pays a stated dividend and has priority over common stock for dividends and liquidation, but usually has limited or no voting rights.

Yield: The income return on an investment, commonly expressed as a percentage. In bond questions, yield often moves inversely to price.

Portfolio, Risk, and Analysis Terms

Asset Allocation: The process of dividing a portfolio among asset classes such as equities, fixed income, and cash equivalents to reflect goals, time horizon, and risk tolerance.

Capital Gain: The profit realized when an investment is sold for more than its cost basis.

Diversification: A risk-management approach that spreads investments across holdings, sectors, or asset classes to reduce concentration risk.

Expense Ratio: The annual operating cost of a fund expressed as a percentage of assets.

Fundamental Analysis: The evaluation of a security using business, financial, economic, and industry information.

Market Capitalization: The market value of a company’s outstanding equity, usually calculated as share price multiplied by shares outstanding.

Return on Investment (ROI): A general profitability measure comparing gain or loss with the amount invested.

Technical Analysis: The evaluation of market activity using price, volume, and chart patterns rather than issuer fundamentals.

Volatility: The degree of price fluctuation in a security or market over time. Higher volatility generally indicates greater uncertainty and price dispersion.

Regulatory and Process Terms

Securities and Exchange Commission (SEC): The U.S. federal agency responsible for enforcing federal securities laws and regulating key parts of the securities markets.

Underwriting: The process in which an investment bank or syndicate helps bring securities to market, including pricing, distribution, and assumption of offering-related risk.

Disclosure: The communication of material information to investors so they can make informed decisions.

Prospectus: The formal offering document describing a new security or investment company offering, including risks, fees, and key terms.

Common Exam Distinctions

Several glossary terms are easy to confuse:

  • Bid versus ask: bid is what the buyer will pay; ask is what the seller wants.
  • ETF versus mutual fund: ETFs trade intraday; open-end mutual funds transact at end-of-day NAV.
  • Coupon rate versus yield: coupon is the bond’s stated rate; yield reflects market price and income relationship.
  • Diversification versus asset allocation: diversification spreads holdings; asset allocation is the higher-level mix across asset classes.
  • Common stock versus preferred stock: common stock carries ownership control features; preferred stock usually emphasizes income priority.

Key Takeaways

  • A glossary is most useful when the term is tied to its exam implication, not just memorized as a definition.
  • Many exam errors come from confusing similar terms such as bid versus ask or coupon versus yield.
  • Product terms, trading terms, and regulatory terms often interact in one question stem.
  • Understanding the term in context helps you answer suitability, risk, pricing, and disclosure questions more accurately.

Sample Exam Question

A customer says, “I want to buy a fund during the trading day when the market dips, and I want to know the price immediately before entering the order.” Which term best identifies the product structure that fits that description?

A. Open-end mutual fund priced once daily at NAV
B. ETF trading intraday on an exchange
C. Zero-coupon bond sold at original issue discount
D. Preferred stock with a stated dividend

Correct Answer: B

Explanation: ETFs trade throughout the day on an exchange and can be bought or sold at market prices during market hours. Open-end mutual funds transact at end-of-day NAV.
