Glossary

0DTE (Zero Days to Expiration)

Options contracts that expire the same trading day. They move fast, pay fast, and can torch a risk plan in a single afternoon.

1099-DIV

The tax form that shows dividends, qualified dividends, and capital gain distributions from stocks and funds. It is the love letter your broker sends to both you and the IRS.

After-tax Yield

What your yield looks like after the IRS takes its cut. It is the real number you can spend without getting surprise bills in April.

Alpha

The slice of return that beats the benchmark after adjusting for risk. Everyone claims to generate it; the expense ratio usually eats most of it first.

Asset Class

A category of investments that behave similarly—equities, fixed income, commodities, real estate. Mixing them is diversification; owning all equities is a mood.

AUM (Assets Under Management)

AUM stands for Assets Under Management — the total market value of all investments (in this case, ETF shares) that a fund manages.

For dividend ETFs, a higher AUM generally indicates:

• Liquidity — Easier to buy and sell shares without wide bid-ask spreads
• Stability — The fund is more established and attracts investor confidence
• Lower costs — Larger funds can spread operating expenses across more assets

For example, if an ETF has $500 million in AUM, that means investors collectively hold $500 million worth of shares in that fund.

Bear Market

Wall Street's version of seasonal depression. Everyone's portfolio goes into hibernation while CNBC pundits explain how you should've sold three months ago.

Boomer Candy

Fancy ETFs that promise safety and monthly income by trading away upside. Basically dessert for retirees: sweet, predictable, and liable to rot your portfolio's teeth if you overdo it.

BDC (Business Development Company)

A public company that lends to or invests in smaller, private businesses and passes most of the income to shareholders. Example: owning a BDC can mean chunky dividends funded by private credit deals.

Beta

A measure of how much an investment moves relative to the overall market. A beta of 1.0 moves with the market, below 1.0 is calmer, and above 1.0 is spicier. Zero beta is a savings account with better marketing.

Bid-Ask Spread

The gap between the highest price a buyer will pay and the lowest a seller will take. Wide spreads are a stealth tax on impatient traders—pay attention before you market-order a thinly traded ETF.

Bull Market

The financial equivalent of a conga line. Nobody knows where it's going, but everyone's convinced it'll last forever. Spoiler: it won't.

CAGR (Compound Annual Growth Rate)

The smoothed annual return that pretends your portfolio grew in a straight line. Reality was choppier, but it's the number marketing decks reach for when they need to sound impressive.

Call Option

A contract that gives the buyer the right—but not the obligation—to buy shares at a set strike price before expiration. Sellers collect premium and root for the stock to stay below the strike.

Call Overwriting

Selling call options against a stock or fund you already own to collect option premium. You trade some upside for steady income, like renting out your spare room and losing privacy.

Calmar Ratio

A risk metric that compares annualized return to maximum drawdown. Higher means you earned more for the worst gut punch your portfolio took.

Capital Gains

The profit when you sell an investment for more than you paid. The IRS cares whether you held it long enough to earn the cheaper long-term rate.

Cash Flow Investing

Building a portfolio with the main goal of steady distributions instead of pure price growth. It is less adrenaline, more direct deposit vibes.

CEF (Closed-End Fund)

A fund that issues a fixed number of shares and trades on an exchange, often at a premium or discount to its NAV. Yields can be fat, distributions can be partly return of capital, and leverage under the hood is common—read the fact sheet twice.

Correlation

How closely two investments move together, from +1 (lockstep) to -1 (opposite directions). Diversification works best when correlation is low or negative, which is rarer than any pitch deck admits.

Covered Call

Selling a call option while owning the underlying shares. You get paid today and agree to sell tomorrow if the price rips higher.

Covered Call ETF

An ETF that holds stocks and sells calls on them for income. It can smooth cash flow, but the upside cap is real and so is the tax bill.

Compound Interest

The closest thing to legal sorcery. You do nothing, your money makes more money, and eventually you can brag about "letting time work for you" while still eating store-brand cereal.

CUSIP (Committee on Uniform Securities Identification Procedures)

A CUSIP is a unique 9-character alphanumeric identifier assigned to securities traded in the United States and Canada. It is used to precisely identify financial instruments such as stocks, ETFs, mutual funds, and bonds for clearing, settlement, and record-keeping purposes.

Think of it as a security's fingerprint. No two should match, and paperwork sleeps better because of it.

Delta

The option Greek that estimates how much an option price moves when the stock moves $1. It is the speedometer for how sensitive the option feels.

Distribution Rate

The annualized payout of a fund expressed as a percentage of its price. It looks like yield's twin, but it can include return of capital and other non-income payments—so read the fine print before you celebrate.

Dividend Yield

The annual dividend divided by the share price. It is a quick snapshot of income, not a guarantee the checks keep coming.

Dividend Aristocrats

S&P 500 companies that have increased their dividend for at least 25 straight years. Example: these are the boring-but-consistent payers that keep hiking even in rough markets.

Diamond Hands

Slang for investors who refuse to sell through gut-wrenching volatility, keeping their grip thanks to long-run conviction. The phrase grew in online trading circles and pairs with the HODL mindset, but it can also mean riding a bad bet far too long.

Dividend Sustainability

Whether a company or fund can keep paying its dividend without raiding the couch cushions. Look at cash flow, payout ratios, and whether the business is melting.

Dividend Coverage

Whether a fund's earnings (or a CEF's net investment income) actually cover the distributions it pays. Coverage below 100% means the payout is borrowing from tomorrow, usually via return of capital.

Dividend Cut

When a company or fund slashes its payout. It's the "we told you so" moment for anyone who ignored warning signs like stretched payout ratios, shrinking cash flow, or management's increasingly creative earnings decks.

Declaration Date

The day a company or fund officially announces an upcoming dividend. It's the "save the date"; record and payment dates follow and determine who actually gets paid.

Downside Protection

Anything meant to soften losses when markets drop, such as hedges, cash buffers, or less aggressive positioning. It is a seatbelt, not a force field.

Drawdown

The peak-to-trough decline in an investment's value before it recovers. A 30% drawdown means you watched a third of your money vanish and had to trust it would come back. Max drawdown is the worst one on record.

Diversification

Putting your eggs in different baskets so when one gets stolen, at least the omelet still happens. The financial world's way of saying "don't be stupid."

DRIP

Dividend Reinvestment Plan. When you're so committed to compounding that you turn every payout into more shares instead of pocket money. Click through if you actually want to learn how to run that flywheel.

Expense Ratio

The annual cost of owning an ETF, expressed as a percentage of your investment. It covers the fund's operating expenses, including:

• Management fees
• Administrative costs
• Marketing and distribution
• Custodial fees

How it works: If an ETF has a 0.50% expense ratio and you invest $10,000, you pay approximately $50 per year in fees (automatically deducted from fund value).

Why it matters:

• Lower is better — Even small differences add up over time. A 0.10% ratio vs. 0.75% ratio saves you significant money over decades
• Affects returns — The expense ratio is subtracted from your total returns
• Varies by strategy — Simple index funds (like broad market ETFs) typically have lower ratios (0.03%–0.20%), while actively managed or specialized funds (like covered call or sector ETFs) often have higher ratios (0.40%–1.00%+)

Example: Two dividend ETFs with the same 5% yield — if one has a 0.20% expense ratio and the other has 0.80%, the first fund's net return to you is higher by 0.60% annually.

ETF Tax Treatment

How an ETF's distributions are taxed based on what it owns and how it operates. Most issue 1099s, but some strategies can kick out ordinary income or capital gains.

Ex-Dividend Date

The cutoff day for dividend eligibility. Buy on or after this date and you miss the upcoming payout. Example: buy the day before ex-date, and you still collect the next dividend.

ETF

An investment burrito stuffed with random securities. Sometimes delicious, sometimes it gives you indigestion, but hey, at least it's portable.

Fund Age / Seasoning

How long a fund has been trading. New funds lack the track record to prove their strategy actually works outside a PowerPoint deck. Generally, two or three years of real data separates "interesting pitch" from "investable product."

Fund Overlap

When two or more ETFs in your portfolio hold the same underlying stocks. You think you're diversified, but your portfolio is just three trench coats sharing one body.

Gamma

The option Greek that measures how quickly delta changes as the underlying moves. High gamma means the position's sensitivity can flip on you fast—great near expiration if you're right, ugly if you're wrong.

Growth vs. Income

The eternal investing tug-of-war: growth chases price appreciation while income chases steady cash flow. Most dividend investors land somewhere in the middle and argue about it online.

Hedge

A position taken to offset potential losses somewhere else in your portfolio. A real hedge costs something up front; a "hedge" that costs nothing is usually just another directional bet wearing a disguise.

HODL

Crypto slang that turned into a buy-and-hold battle cry. It pushes long-term conviction during wild price swings and shrugs off panic selling, for better or for worse.

Income Investing

Focusing on assets that pay you regularly, like dividends, interest, or option income. The goal is more cash flow and fewer sweaty palms.

Index Fund

A fund that tracks a rules-based basket instead of trying to pick winners. Boring by design, which is exactly why it quietly beats most active managers over long stretches.

Issuer Concentration

How much of your portfolio is managed by a single fund company. Owning five JPMorgan ETFs isn't diversification, it's brand loyalty with extra steps.

Inception Date

The date a fund first started trading. Younger funds have less history to judge, so an early inception date is like a long resume—not a guarantee, but reassuring.

Junk Bond

A bond rated below investment grade, paying a higher yield because the issuer is more likely to ghost you on repayment. High income, high drama.

K-1

If it pumps, processes, pressurizes, or pipes hydrocarbons, it probably hands you a K-1. It's a tax form partnerships send instead of a standard 1099, stuffed with allocations and passive loss trivia your software never guesses right. Translation: extra waiting, extra clicks, and extra chances to get cozy with the IRS instructions.

Leveraged ETF

An ETF that uses derivatives to multiply daily returns—typically 2x or 3x. Great for short-term tactical plays, brutal for buy-and-hold because volatility decay slowly shaves off the promised multiple.

Liquidity

How fast you can turn an asset into cash without looking like you're pawning grandma's heirlooms. High liquidity means tight bid-ask spreads and enough volume to exit gracefully; low liquidity means every trade moves the price against you.

M2 Money Supply

A broad measure of money that includes cash, checking deposits, and easily accessible savings instruments. Think of it as the economy's wallet plus the couch cushions—full until someone remembers all those impulse buys.

Managed Distribution Policy

A fund's commitment to pay a preset distribution rate regardless of what the portfolio actually earned, topping up with capital gains or return of capital as needed. Predictable income on the surface; potential NAV erosion underneath.

MLP (Master Limited Partnership)

A publicly traded partnership, often in energy infrastructure, that passes through most of its cash flow to investors. Example: MLPs can pay high distributions but usually send a K-1 at tax time.

Monthly Income ETF

An ETF designed to distribute income every month. It is for people who want a regular paycheck cadence instead of waiting for quarterly surprises.

NAV (Net Asset Value)

The value of a fund's holdings divided by its shares outstanding. It is the fund's report card, not the price you can always trade at.

NAV Erosion

When a fund's net asset value drifts lower over time, often because distributions exceed true earnings. It is the slow leak that makes yield look better than reality.

NAV Trend

The directional pattern of a fund's net asset value over time. A steady climb means the engine is healthy, while a slide hints the payouts are eating the chassis.

Option Premium

The cash you receive for selling an option. It feels like found money until you remember you sold someone a promise.

Omega Ratio

A performance measure that compares gains above a target return to losses below it. The higher it is, the more upside you got relative to the downside drama.

Ordinary Income

Income taxed at your regular rate, like interest or many option distributions. It is the opposite of the fancy lower tax brackets.

Passive Income (Investing Context)

Money you earn without clocking in, like dividends or interest. It is passive only after you do the active work of picking the right assets.

Payout Ratio

The share of earnings or cash flow a company uses to pay dividends. A ratio above 100% means the company is paying more than it earns—fun at parties, unsustainable long-term.

Payment Date

The day a dividend actually lands in your account. Not to be confused with ex-date or record date—this is when the money hits.

Paper Hands

Trading slang for someone who bails at the first whiff of red, locking in losses out of fear. It is often used in crypto and meme-stock chatter to call out shaky conviction and missed rebounds.

Premium/Discount to NAV

The gap between a fund's market price and its net asset value. ETFs usually trade within a hair of NAV thanks to the creation/redemption mechanism; CEFs can swing wildly above or below, and that spread is half the game.

Put Option

A contract that gives the buyer the right—but not the obligation—to sell shares at a set strike price before expiration. Buyers use them as insurance; sellers collect premium hoping the stock stays above the strike.

Qualified Dividends

Dividends that meet IRS rules and get taxed at lower long-term capital gain rates. They are the polite, well-dressed dividends that behave.

Record Date

The cutoff day for the shareholder list that gets the next dividend. Not on the books by this date and the payout skips you—regardless of whether you bought the day after.

Reverse Split

When a company or fund combines shares to raise the price per share. It fixes the look, not the underlying problem.

REIT (Real Estate Investment Trust)

A company that owns or finances income-producing real estate and distributes most of its earnings. Example: a REIT can pay steady dividends funded by rent checks.

Retirement

The last stop before Valhalla, where you move to Florida and become a shuffleboard champion the likes of which the SeaShell Villages have never seen. Also known as: "When your boss finally becomes someone else's problem."

Risk-adjusted Return

The return you get after accounting for how wild the ride was. It is the reason a boring strategy can beat a rollercoaster on a quality-of-life basis.

Return of Capital (ROC)

A distribution that gives you your own money back dressed up like income. It feels fancy until tax time reminds you it's basically a slow-motion refund. Dive deeper in the Learning Lab before you start celebrating.

SEC Yield

A standardized 30-day yield the SEC forces funds to publish, based on net investment income over the trailing period. It's the apples-to-apples number; distribution rate is the marketing number. When they disagree, the gap is often return of capital.

Section 199A

The tax code section that grants a 20% deduction on qualified REIT dividends and certain pass-through income. It's why REIT dividends taste slightly less bitter at tax time—assuming Congress doesn't let it expire.

Sequence of Returns Risk

The danger that the order of investment gains and losses hurts long-term results, especially when you're withdrawing money. It's like eating your fries before the burger only to realize the burger's burnt—you're stuck with the aftertaste.

Sharpe Ratio

A risk-adjusted return score that compares excess return to volatility. Higher means you got paid more for the stress.

Sortino Ratio

Like Sharpe, but it only counts downside volatility. It rewards strategies that keep the bad days quiet while still delivering returns.

Strike Price

The price at which an option contract can be exercised. Above it for calls, below it for puts, is where the math (and the assignment risk) actually matters.

Tax Drag

The performance loss from paying taxes along the way. High turnover strategies can feel like running with a parachute.

Tax Loss Harvesting

Selling investments at a loss to offset taxable gains, then reinvesting to stay allocated. It is the portfolio version of turning lemons into a tax break.

Tax-efficient Investing

Choosing assets and strategies that minimize taxes so more of your return stays yours. It is the difference between gross and actually getting paid.

Theta

The option Greek that measures time decay. It's the daily rent the clock charges an option holder just for owning a contract that hasn't moved yet—and it accelerates near expiration.

Total Return

The full return on an investment, including price change and all distributions reinvested. It's the only number worth comparing across strategies—pure yield figures are easy to game.

Tracking Error

How much an index fund drifts from the benchmark it's supposed to mirror. Low is good; high means you're paying index-fund fees for unintentionally active performance.

Turnover

The percentage of a fund's holdings swapped out in a year. High turnover usually means higher taxes and hidden trading costs that never show up on the fact sheet.

Upside Cap

The maximum gain you can earn in a strategy like covered calls. You take the premium and agree to stop winning after a certain point.

Ulcer Index

A risk measure that focuses on depth and duration of drawdowns, not just volatility. Lower is better because your portfolio spent less time in pain.

Vega

The option Greek that measures sensitivity to implied volatility. When the market gets jumpy, vega is what makes option prices jump with it—regardless of whether the stock itself has moved yet.

Volatility

How much prices swing around. High volatility means bigger moves, higher drama, and more potential for both profits and ulcers.

Volatility Harvesting

Strategies that try to monetize price swings, often by selling options. It is paid for absorbing other people's chaos.

Wash Sale

Selling at a loss and buying the same (or substantially identical) security within 30 days, which disallows the tax loss. The IRS's polite way of saying "nice try."

Weekly Income ETF

An ETF structured to pay distributions every week. It is for investors who want income faster than the calendar usually allows.

Withdrawal Rate

The percentage of your portfolio you pull out each year in retirement. The classic "4% rule" says you can withdraw 4% annually and probably not run dry. Probably.

XIRR

The spreadsheet formula that calculates an annualized return on cash flows with irregular dates. It's what you reach for when dollar-cost averaging and uneven contributions break a plain percentage calculation.

Yield Trap

A sky-high yield that lures you in right before the dividend gets cut or the price falls. It is the financial version of a too-good-to-be-true deal.

Yield on Cost

Dividend yield based on what you paid, not today's price. Example: a stock bought at $50 paying a $3 dividend has a 6% yield on cost, even if it trades at $75 now.

Zero-Coupon Bond

A bond sold at a discount that pays no coupons, just a lump sum at maturity. You earn "income" via price appreciation, except the IRS still taxes the imputed interest every year—phantom income with a real tax bill.
