Since the name of this website is a play on words, and I occasionally use wordplay to create a clever or amusing quip to keep your attention from waning, it is only fitting that I write about the most misunderstood words in the investment industry.
Few outside of finance appreciate investment jargon. It would be like your spouse using their unique industry terms in your dinner conversation. “Let’s put the dishes in the ‘clean room for the automatic fill-finish’ cycle before we ‘gown up to do a Gemba walk’ on the ‘manufactured’ sidewalk ‘floor’.” To the outsider, it would sound absurd. (Sterile pharmaceutical manufacturing or as I once described my husband’s profession in a loud, crowded restaurant next to a table of deputy sheriffs, he makes drugs!)
Being an investor in any form, you do need to understand financial industry terms, some being more important than others. And the more you know, the better you understand. If I gave you a list of terms and definitions like most investing articles do, you would stop reading at this point but I’m not.
Knowing the different types of Markets and its history and understanding and remembering the difference between a Bull and Bear market are high on the list.
However, the most searched financial industry term is ETF followed by IPO (Initial Public Offering). For the ordinary investor, ETFs are much more important to understand than IPOs. You will likely have an ETF fund in one of your accounts rather than a single stock from an IPO. The most recent notable initial public offering was the IPO of SpaceX on June 12, 2026. Jersey Mike’s IPO was July 29, 2026, and the highly speculated IPO of Anthropic, the developer of Claude.ai is anticipated later this year.
This segues into Risk vs. Volatility since this is now high on the list with AI, when you ask it for input on the most misunderstood investing terms and as an aspect of the technology itself. Most people think risk is the probability that you will permanently lose all of your money. There are several facets to risk some being impossible to measure. Risk also varies within the context that it is used.
The simplest definition of risk in investing is the uncertainty that an investment will make less money than you expected, or that you could lose some or all of your original investment. Solely investing in Enron embodies the definition of exceptional risk. Thousands of employees and individual investors had a massive, and in many cases near-total, portion of their life savings and personal net worth tied up solely or predominantly in Enron stock. It is why diversification (deserves an entire future post) is so important.
Volatility is a measure of how much and how quickly the price of an investment moves up and down over a period of time. It is just the turbulence of the roller coaster ride. Tesla (TSLA) is a highly volatile stock. It frequently sees large daily and intraday price gaps, making it desirable for active day and options traders. Crypto is also a highly volatile investment.
Crypto is also considered a liquid asset. Coins like Bitcoin and Ethereum are very liquid because they trade continuously on global exchanges with high daily volume allowing you to convert them to cash or other tokens in literally seconds. Liquidity is the ability to sell assets that can be converted into spendable cash quickly and easily with little to no loss in value. Other examples include money market funds, U.S. government bonds and stocks within your brokerage account. Liquidity is not having a lot of money, being rich or a positive net worth.
And where investing words matter more than ever is in today’s prediction markets. Prediction markets are online platforms where participants buy and sell shares or contracts tied to the outcomes of future events, such as elections, economic data, weather and sports. (Fidelity) Unlike traditional casinos where you play against the house, participants trade directly against one another (peer-to-peer), while the platform makes money through transaction fees.
Investing holds the expectation that the money placed in an asset will grow in value or generate income over time despite the risk that it may lose value. Whereas gambling is placing money or something of value on an uncertain event or game of chance with the hope of winning a larger prize or the risk of losing that money completely.
When I wrote The Luck and Skill of Investing, I referred to sports betting as sports gambling. At first I want back to change it, but decided to intentionally leave it because that is what I thought it truly was. As it turns out, I’m not the only one. Of the 50 states, 44 have signed a letter to the Commodities Futures Trading Commission (CFTC) claiming that prediction market companies like Kalshi are evading state gambling laws. Kalshi alone faces 80 federal docket matters with 55 open including 25 lawsuits. However, the prediction market companies maintain they are federally regulated derivatives exchanges.
A derivative is a financial contract between two or more parties whose value is derived from the performance of an underlying asset, group of assets, or benchmark (such as stocks, bonds, commodities, currencies, interest rates, or market indexes). Prediction market companies are attempting to fit themselves into a category similar to the Digital Asset / Crypto Derivatives Exchanges where listing perpetual swaps, futures and options are tied to events rather than cryptocurrencies (Bitcoin and Ethereum).
A few other investing words that are important to understand are dividend yield, CAGR, ask/bid and FU Money.
Dividend yield is often mistaken as “free money” or a guaranteed baseline income paid out passively in addition to stock price growth. The reality is a company’s board cannot manifest money out of thin air. If a stock trades at $100 and pays a $3 dividend, the stock price immediately drops to $97 on the ex-dividend date. If this occurs inside a regular brokerage account, you now owe taxes on that $3 payout. Essentially, you are forced to sell 3% of your investment and pay taxes on it. You can cash out or reinvest the dividends, but you still pay taxes regardless.
To know the real mathematical growth rate of your money, you must always look for the CAGR (Compound Annual Growth Rate) not just the average returns.
Ask and Bid also matter. The ask is the amount a seller is willing to accept for a security, while the bid is the amount an investor is willing to pay for it. The greater the spread between these two numbers, the more liquid an asset is.
And finally, FU Money is exactly what you think it is. In 2026, it refers to having enough liquid savings, cash or investments to walk away from any job, toxic environment or bad situation without worrying about immediate bills.
There are dictionaries and glossaries of investing words. You will never know all of them or what they all mean or how exactly they play into your personal investing circumstances. However, if you come across something that you think is applicable to you or you want to know more about or your financial advisor/planner mentions it to you, don’t hesitate to search for a greater explanation or ask for one. I have found that the more I write, the better I get at playing Scrabble in my ultra-competitive family game, the ultimate play on words where words matter.
Featured Image – This is a Money Tree with its characteristic braided trunk and distinctive leaves. It was upstairs in a west-facing bedroom window bench that had a lot of tree cover and had grown well. So, we moved it to our great room that faces east thinking it would grow even more with direct sunlight and a new pot. Instead, most of the leaves turned yellow and fell off. The picture below is from May and by August my husband was ready to toss it. We had essentially fried it.
Your money (tree) rebounds when invested in the right environment for it to thrive and compound. The Money Tree is known for good luck and financial prosperity (Feng Shui).
I rolled it (notice the wheels, husband’s idea) to my office which is actually the “formal living room” at the front of the house again. Formal living has waned but the money tree has not. Photographed today.
