a

Acquisition

A type of corporate action that occurs when one company purchases a majority stake in another company. Acquisitions can be paid for in cash, stock, or a combination of the two. 

Assignment

A short option, regardless of whether it’s a call or put, can be assigned at any time if the option is in the money. When selling a put, the seller is contractually giving the right for the put owner to sell or “put” them stock at a given price (Strike Price) in a given set of time (expiration). Selling a call gives the right to the call owner to buy or “call” stock away from the seller within a given time frame. The purchaser of an option has the right to exercise an in the money option at any time prior to expiration, but not necessarily the obligation to do so. Short options are most commonly assigned if the options expire in the money, or if there is a dividend paid out (Dividend Risk).

b

Bearish

A pessimistic outlook on the price of an asset. Traders who believe that an asset price will depreciate over time are said to be bearish.

Beta Weight

Beta weighting is a means for investors to put all of their positions into one standard unit. It is a way to look at an entire portfolio and understand how it will change with a move in the market. It tells us about the size, diversity and general risk of our positions.

Learn More

Broken Wing Butterfly

A Broken Wing Butterfly is a long butterfly spread with long strikes that are not equidistant from the short strike. This leads to one side having greater risk than the other, which makes the trade slightly more directional than a standard long butterfly spread.

Learn More

Butterfly Spread

A 3-strike price spread that profits from the underlying expiring at a specific price.

c

Calculating Expected Move

Expected move is the amount that a stock is predicted to increase or decrease from its current price, based on the current level of implied volatility for binary events.

Learn More

Calendar Spread

A Calendar Spread is a low-risk, directionally neutral strategy that profits from the passage of time and/or an increase in implied volatility.

Learn More

Cash Settled

Cash settled financial instruments simply settle to cash instead of the underlying instrument at expiration. There are a few notable differences that cash settled instruments have when compared to other instruments like ETF’s like the SPY.

Learn More

Correlation

Correlation is the relationship between two or more variables with a range of negative (-1) to positive (+1). It is generally measured on a historical basis with a minimum of one month. Correlation measures the rate at which two stocks have historically tended to move in relation to their mean. If they are normally on opposite sides of the mean, they tend to move in opposite directions and have a negative correlation. If they are normally on the same side of the mean, they tend to move in the same direction and have a positive correlation. If there is no clear trend, they are said to have little to no correlation (0). Understanding correlation allows us to diversify our portfolio in non-correlated underlyings.

Learn More

Covered Call

A Covered Call is a common strategy that is used to enhance a long stock position. The position limits the profit potential of a long stock position by selling a call option against the shares. This adds no risk to the position and reduces the cost basis of the shares over time.

Learn More
d

Diagonal Spread

A Diagonal Spread is constructed by purchasing a call/put far out in time, and selling a near term put/call on a further OTM strike to reduce cost basis. The trade has only two legs, but it gives the effect of a long vertical spread in terms of directionality, and a calendar spread in terms of its positive vega.

Learn More

Dividend

A dividend is a cash distribution, usually quarterly, to shareholders based on company profits. Investors that own the stock receive the dividend. Investors that are short the stock are required to pay the dividend. Dividends are non-events from a P/L basis. When dividends are paid, the stock price is reduced by the amount of the dividend so that no arbitrage opportunity exists. With that said, it is still important to know when a dividend is coming out, to see if your option position is at risk.

Learn More
e

Earnings

Earnings announcements are public announcements that display a company’s earnings, or lack thereof. These usually take place on a quarterly basis. This number is generally quantified as “earnings per share.” It’s important to understand how earnings can affect an underlying, as well as that underlying’s option market.

Learn More

Earnings volatility

Earnings volatility is different from standard volatility because it is inflated by a binary event. Earnings are announced either before the market open or after the market close and volatility is typically at its peak just before the announcement. This is due to the uncertainty of stock direction and the magnitude of the move after the earnings announcement.

Learn More

Expected Returns

Trading options allows us to take advantage of leverage, which can greatly increase our expected returns on a trade. This leverage also increases our risk. Because of the risk we are taking on, we expect our returns to be greater than the risk-free rate of return (which are virtually non-existent in a low IV environment).

f

Fundamental Analysis

An investing/trading methodology that estimates a security’s fair value using relevant quantitative and qualitative information. The goal of this approach is to compare the result of fundamental analysis to the current market value of a security to determine whether it is undervalued, overvalued, or fair.

Futures

Contracts that require buyers to purchase and sellers to sell an asset (financial instrument or physical commodity) at a specified price at a specified future date. At tastytrade, we use futures to scalp, hedge and give us an overall sense of market activity.

Learn More

Futures Options

Options on futures are similar to options on stocks, but with one major exception…Futures are the underlying instrument off which the options are priced (unlike equity options which have the stock as its underlying). As a function of being priced off of futures, it’s important to be aware of the differences between futures options and equity options.

g

Gamma

Gamma is the greek that gives us a better understanding of how delta will change when the underlying moves. It is literally the rate of change of an option’s delta, given a $1.00 move in the underlying. For example, if a long call option has a gamma of 0.10 and a delta of 0.50, and the underlying moves up $1.00, the option will then have a delta of 0.60, all else equal. There are a few important concepts when it comes to gamma: Long option benefits, short option risks, and expiration risk.

Learn More

Greeks

In finance, the “Greeks” are parameters that measure the sensitivity of an option’s value to changes in the following: underlying price, time, volatility, and interest rates. These measurements are collectively known as the “Greeks” because they are denoted by letters from the Greek alphabet, including: delta, gamma, theta, vega, and rho.

High IV, Low IV

Implied Volatility refers to a one standard deviation move a stock may have within a year. If a stock is $100 with an IV of 50%, we can expect to see the stock price move between $50-150. The lower the IV is, the less we can expect to see the stock price fluctuate, and vice versa. These environments tend to be extremes, so we are very mindful of them and act fast when they arise.

Learn More
i

IV Rank

A metric which tells us whether implied volatility is high or low in a specific underlying based on a given time frame of IV data.

Implied Volatility

Implied volatility (commonly referred to as volatility or IV) is one of the most important metrics to understand and be aware of when trading options. Implied volatility in the stock market refers to the implied magnitude, or one standard deviation range, of potential movement away from the stock price in a year's time.

Iron Condor

An Iron Condor is a directionally neutral, defined risk strategy that profits from a stock trading in a range through the expiration of the options. It benefits from the passage of time and any decreases in implied volatility.

Learn More

Iron Fly

An Iron Fly is essentially an Iron Condor with call and put credit spreads that share the same short strike. This creates a very neutral position that profits from the passage of time and any decreases in implied volatility. An Iron Fly is synthetically the same as a long butterfly spread using the same strikes.

j

Jade Lizard

A Jade Lizard is a slightly bullish strategy that combines a short put and a short call spread. The strategy is created to have no upside risk, which is done by collecting a total credit greater than the width of the short call spread.

Legging Into and Out of Trades

Legging a trade refers to the opening or closing of each leg for a non-naked strategy in separate transactions.

Learn More

Limiting profitability

There is a direct relationship between profitability and probability of success. The higher the profitability, the lower the probability of success. At tastytrade, we limit our profitability to increase our probability of success. We do this by reducing our cost basis and by selecting our strikes strategically, to give us a high probability of success. This is one of the hardest concepts to grasp as a new trader so we like to use a baseball analogy to explain the concept…

Learn More

Liquidity

Liquidity is how easily an investor can buy or sell an asset without losing much value. The more an asset is traded, the more liquid it becomes.

Learn More

Long Butterfly Spread

A long butterfly spread is a neutral position that’s used when a trader believes that the price of an underlying is going to stay within a relatively tight range.

Market Awareness

Market awareness refers to our ability to assess the entire stock and option marketplace from a macro level. Having a better market awareness allows us to avoid poor decisions and optimize our good ones. We like to break market awareness down in three levels: Sector awareness, fear awareness & participant awareness.

Learn More

Mean Reversion (Contrarian)

Mean reversion is very important to what we do at tastytrade. As mean reversion traders, we look to exploit price extremes and volatility because we believe they will revert to their mean over time. Volatility proves to be the one variable that is recognized as being ‘mean reverting’ in many option-pricing models.

Measuring Implied Volatility

Let’s imagine for a second that you live on the beaches of Florida (or maybe you do already!) If you see the water levels of the beach each day, you can easily tell when the water levels are high or low. A tourist, however, may just come to the beach for the first time and think an extremely high or low water level is normal. You have the ability to put context around the water levels, where the tourist does not. That’s the importance of measuring implied volatility (IV) - putting context around IV levels that we’re seeing. At tastytrade, we focus on two measurements - IV Rank & IV Percentile.

Naked Options

Short “naked” options are calls or puts that are sold that have nothing to limit their risk (shares of stock, long options). It is a bullish strategy when selling a put option and a bearish strategy when selling a call option.

Learn More

Notional Value

The notional value of a position is the real amount at risk, excluding margin relief. If we own 100 shares of stock at $50.00 per share, we have $5000 of notional value at risk. If the stock price drops to $0.00, we stand to lose $5000. In a margin account, we are offered 2:1 leverage on stock purchases. What does this mean? Basically, that same 100 shares of stock would only require $2500 of capital to purchase. What we have to remember is that we still have that same $5000 of notional value. In other words, we only have to put up $2500 at first, but if the stock price goes to $0.00 we still lose $5000. 

Learn More

Number of Occurrences

When it comes to probabilities, we have to understand that there are winners and losers. Even if we have a 99% probability of success on a trade, one percent of those trades will still be losers over a very large pool of occurrences. Let’s say that we reach our true probability over 1000 occurrences. We could expect to see 990 winners and 10 losers. The question is - where will those 10 losers occur? Nobody knows, and that’s the importance of trading small.

Option Value

Where an option gets its price can seem like smoke and mirrors when first learning about option trading, but it is actually pretty simple. Option value, also known as option premium, is really just made up of two contributing factors - intrinsic & extrinsic value. These values change based on three inputs: strike price in relation to the stock price, implied volatility, and time until expiration. That’s it! We won’t leave you there though - let’s dive a little deeper and start with intrinsic value.

Learn More

Options Expiration

The date at which an option stops trading, and all contracts are exercised or become worthless. Expiration is one of the differentiating factors between stocks and options. As long as a company is publicly traded, there is no expiration on shares. Options, on the other hand, have expirations.

Poor Man Covered Put

A “Poor Man’s Covered Put” is a Put Diagonal Debit Spread that is used to replicate a Covered Put position. The strategy gets its name from the reduced risk and capital requirement relative to a standard covered put. The strategy is also much safer than a covered put because there is no naked short stock component.

Learn More

Pot Odds

The term “pot odds” refers to the statistical relationship between expected return and expected risk. If we have good pot odds on a trade, we can expect to make more than what we’ve risked. For example, we would risk two to make three, but we would not risk four to make three in a random environment.

Learn More

Probability of Profit

Probability of profit (POP) refers to the chance of making at least $0.01 on a trade. This is an interesting metric that is affected by a few different aspects of trading - whether we’re buying options, selling options, or if we’re reducing cost basis of stock we are long or short.

Ratio Spread

A front ratio spread is a neutral to slightly directional strategy placed so that there is either no upside or downside risk. A Front Ratio Spread is created by purchasing a put or call debit spread with an additional short put or call at the short strike of the debit spread.

Learn More

Risk Management

Risk Management refers to the strategic risk that we take when trading options. This covers everything from our trade size, to our strike selection, product choice and type of strategy. We are able to control all of these factors in order to increase our probability of success and avoid large drawdowns in our account.

Staying Small

While traditional investing advocates for fewer occurrences and values the buy and hold strategy, we at tastytrade take a statistical approach to trading. We believe in putting on many small high probability trades to increase our probability of success.

Straddle

A short straddle is a position that is a neutral strategy that profits from the passage of time and any decreases in implied volatility. The short straddle is an undefined risk option strategy.

Strangle

A short strangle is a position that is a neutral strategy that profits when the stock stays between the short strikes as time passes, as well as any decreases in implied volatility. The short strangle is an undefined risk option strategy.

Learn More

Strike Price

A strike price is the price in which we choose to become long or short stock using an option. Unlike stock where we’re forced to trade the current price, we can choose different option strikes that are above or below the stock price, that have different premium values and probabilities of profit. When choosing strikes, there are a few crucial concepts: The probability of the option expiring worthless, and whether the option is in the money (ITM), at the money (ATM) or out of the money (OTM).

Theta

Theta is the daily decay of an option’s extrinsic value. This metric is the cloudiest of all, as it assumes implied volatility & price movement are held constant. For this reason, it’s better to think of theta decay from the bigger scheme of things.

Triple Witching

Triple witching refers to one of the four days a year when index futures, index options and stock options expire on the same day.

Twisted Sister

A twisted sister is a neutral, undefined risk strategy. This strategy is the opposite of a jade lizard. To construct this strategy we would sell an OTM call, and sell an OTM put spread at the same time. Maximum profit is achieved if the stock price ends up between the short strikes at expiration. We have found that twisted sisters underperform in the long run when compared to jade lizards because jade lizards take advantage of volatility skew.

Undefined Risk

Undefined Risk refers to the risk that is accompanied with naked options and when your possible max loss is unknown on order entry. This normally refers to a naked call as the underlying equity could possibly go up indefinitely. Naked puts also have undefined risk, however we know that an underlying can only go to zero so we can consider this our max loss.

Vega

One of the Greeks, vega measures the rate of change in an option’s theoretical value given a 1% change in implied volatility.

Vertical Spread

A vertical spread is a directional strategy made up of long and short puts/calls at different strikes in the same expiration. Vertical spreads allow us to trade directionally while clearly defining our maximum profit and maximum loss on entry (known as defined risk).

Volatility Products

In recent years, it has become increasingly common to consider volatility as its own asset class. With this progression, many different volatility products have been invented and are now available to trade. The most common of these products include the VIX, VIX options, VIX futures, VXX, UVXY, SVXY and VXST. The VIX index gauges 30-day implied volatility in SPX and the options on the VIX allow investors to trade their volatility assumptions, whether it is to speculate or hedge portfolio positions.
