Investing Concepts

Compound interest is when your earnings start earning too. Returns build on previous returns, so growth can speed up the longer you stay invested.

Why it matters: It is one of the main reasons starting early and staying invested can matter so much.

Diversification means spreading your money across different investments so no single one can sink the whole portfolio.

Why it matters: It is a simple way to reduce the risk that comes from depending on one outcome.

Dollar-cost averaging means investing a fixed amount on a regular schedule, regardless of price, instead of trying to time the market.

Why it matters: It smooths out the price you pay over time and removes some of the guesswork and emotion.

Risk tolerance is how much ups and downs you can handle, financially and emotionally, without abandoning your plan.

Why it matters: Knowing it helps you choose investments you can actually hold through rough patches.

Asset allocation is how you divide your money among types of investments, such as stocks, bonds, and cash.

Why it matters: It is often the biggest driver of how a portfolio behaves over time.

Inflation is the gradual rise in the general level of prices, which means each dollar buys a little less over time.

Why it matters: It affects the real value of savings and is one reason people invest rather than hold only cash.

A recession is a period when the economy shrinks for a while, often with slower spending, lower output, and rising unemployment.

Why it matters: Recessions are part of the normal economic cycle, so understanding them helps you stay calm when headlines turn negative.

A Treasury yield is the return the U.S. government pays to borrow money for a set period, such as ten years.

Why it matters: It is a key reference rate that influences mortgages, savings rates, and how investors value other assets.

A bond is a loan you make to a government or company that pays interest over time and returns the original amount at the end.

Why it matters: Bonds are often used to add steadier income and to balance the swings of stocks.

Volatility describes how much and how quickly a price moves up and down. Higher volatility means bigger swings.

Why it matters: It is a common way to think about short-term risk, though large swings are normal for some assets.

Liquidity is how easily you can trade something without moving its price much. Cash is the most liquid; a house is not.

Why it matters: Investments that are hard to sell quickly can be riskier to rely on in an emergency.

An ETF, or exchange-traded fund, is a basket of investments you can trade like a single stock during market hours.

Why it matters: ETFs make it easy to own many assets at once, often at low cost.

An index fund tries to match a market index, such as the S&P 500, rather than trying to outperform it.

Why it matters: By holding the whole market at low cost, index funds remove a lot of guesswork.

Market capitalization is the total value of a company's shares, found by multiplying the share price by the number of shares.

Why it matters: It is a quick way to gauge a company's size and is used to group firms as large, mid, or small cap.

Valuation is an estimate of what an investment is worth, based on things like earnings, growth, and assets.

Why it matters: Comparing price to a careful estimate of value sits at the heart of many investing styles.

The price-to-earnings ratio, or P/E, compares a company's share price to its earnings per share.

Why it matters: It is a common shorthand for how expensive or cheap a stock looks relative to its profits.

Dividend yield is the annual dividend a company pays divided by its share price, shown as a percentage.

Why it matters: It helps investors compare the income that different dividend-paying stocks provide.

Bitcoin is a digital money that runs on a global network with no central authority and a fixed supply of 21 million coins.

Why it matters: It was the first cryptocurrency and remains the largest and most widely followed.

A blockchain is a shared digital record kept by many computers at once, which makes it hard to alter or shut down.

Why it matters: It is the technology that lets cryptocurrencies work without a central middleman.

A stablecoin is a cryptocurrency designed to hold a steady value, usually by tracking a currency like the U.S. dollar.

Why it matters: Stablecoins are often used to move value between crypto assets without the usual price swings.
