Trading Terminology: Top 20+ Slang Words Used by Traders

Trading Terminology

Though trading slang words are not typically considered professional or conventional, they are still used extensively by traders worldwide. You, too, should build your trading vocabulary as you go further with your trading efforts, so you can communicate like a pro.

In the beginning was the word

Human activity is endless. There are countless areas where we apply our intellectual and physical abilities. Often, fields of occupation require a specific language – a jargon. This is a way for those involved to communicate quickly and effectively.

Trading is no exception. There are many finance idioms and terms that market players use extensively. Knowing stock investment terminology is crucial for anyone who is serious about trading.

Below, we will give you the most popular trading expressions you can use to make the best of your everyday trading.

Slang from all over the place

Where do finance idioms come from? The short answer is, from everywhere. This is not an exaggeration. As you will see, these terms are inspired by multiple sources: nature, geography, cultural stereotypes, space, history, pop culture, and even fairy tales. Some may seem out of place or downright weird, but as soon as you learn their meaning and reference, you’ll see that they make perfect sense.

Welcome to the jungle

The market can get scary and ruthless, just like a wilderness full of relentless predators. That is why investment terminology has so many animal terms —bulls, bears, hawks, doves, and so on. Most commonly, animal-related trading terms refer to different styles of market behavior.

For instance, a bear trader is a pessimist, whereas a bull has a more positive outlook. The same approach applies to the market environment: a bearish market with poor perspectives or a bullish one with an upward trend.

Relationship stuff

Most things in life come in pairs. This is 100% true for the Forex market, where currencies get together in pairs and make you anxious as they shift in value. It makes sense that traders have come up with a bunch of substitutions for the world’s biggest currency pairs.

Here’s what you may come across when trading Forex pairs:

Aussie (Ozzie) and Matie for AUDUSD.

Cable for GBPUSD.

Barney for USDRUB.

Betty for EURRUB.

Loonie for USDCAD.

Ninja for USDJPY.

Swissy for USDCHF (Swiss franc).

While not a currency pair term, Kiwi is what traders often call the New Zealand dollar.

To the moon and back

Now it’s about time we found out what specific terms traders use to describe various market movements. There are at least five phrases you will hear a lot while trading.

To the moon or mooning describes an often very quick, shockingly high spike in an asset’s price.

Tanking is the opposite. This term is used when a price drops fast and deep. Not something any investor would want to witness, but these things happen.

A short squeeze happens when many bet against a stock, but then its price suddenly soars. In this case, short sellers try to close out their positions ASAP.

A long squeeze is when an asset’s price suddenly drops, pushing long holders to sell their assets to avoid potential losses.

Finally, traders can get themselves jigged out by reading the market movements wrong. This means that a trader leaves the market just before the market takes a sudden positive turn.

Tech talk

Trading techniques are a broad area with several curious terms. We have chosen the bare minimum of what a beginner trader should know for this guide.

Fading is when a trader chooses to go against trends. That’s a bold tactic that requires long-term experience, so only top pro traders can afford to apply it.

Pump and dump is not a trading technique per se, but a scheme. It’s the process of pumping stock prices using false information to cause hype around the asset. And then, when the price is high enough, stocks are dumped into the market. It’s highly unethical and illegal.

Squiggly lines is a common term for indicators that traders use to follow the market.

When things get odd

Just as you’re beginning to think that stock market jargon is nothing that crazy, all of a sudden, you come across something like this:

  • Bagel land for an asset that is about to drop to 0.

  • Cockroach theory for suspicion of more bad news behind the scenes.

  • Dead cat bounce for a short-term rise in the price of a degrading asset.

  • Godfather offer for an offer impossible to refuse. A nod to the Godfather movie saga.

  • Smurf for a money launderer.

  • Suicide pill for a company’s desperate tactic to avoid a takeover via a set of self-destructive actions. This strategy sometimes goes by the even murkier name “Jonestown Defense,” inspired by the 1978 mass suicide in Jonestown, Guyana.

  • Zombie debt for long-forgotten debt.

The list could go on with “killer bee,” “ankle biter,” “eat your own dog food,” “rust bowl,” “Crummey power,” and other peculiar terms to show you that stock market lingo is full of surprises.

The power of the word

Knowing the most common stock market words and expressions helps you feel more confident with the market. It gives a broader understanding of contexts and events, lets you interpret them properly, and opens a whole new plain of communicative opportunities. As a result, it makes for more efficient trading.
