A positive butterfly is a non-parallel yield curve shift that occurs when short- and long-term interest rates shift upward by a greater magnitude than medium-term rates. This shift effectively decreases the overall curvature of the yield curve.
A positive butterfly may be contrasted with a negative butterfly, and should not be confused with the options strategy known as a long butterfly.
Key Takeaways
A positive butterfly occurs when there is a non-equal shift in a yield curve caused by long- and short-term yields rising by a higher degree than medium-term yields.
A butterfly suggests a "twisting" of the yield curve, creating less curvature.
A common bond trading strategy when the yield curve presents a positive butterfly isto buy the "belly" and sell the "wings."
The yield curve is a visual representation that plots the yields of similar-quality bonds against their maturities, ranging from shortest to longest. The yield curve shows the yields of bonds with maturities ranging from 3 months to 30 years and thus enables investors at a quick glance to compare the yields offered by short-term, medium-term, and long-term bonds.
The short end of the yield curve based on short-term interest rates is determined by expectations for the Federal Reserve (Fed) policy; it rises when the Fed is expected to raise rates and falls when interest rates are expected to be cut. The long end of the yield curve, on the other hand, is influenced by factors such as the outlook on inflation, investor demand and supply, economic growth, institutional investors trading large blocks of fixed-income securities, etc.
In a normal interest rate environment, the curve slopes upward from left to right, indicating a normal yield curve. However, the yield curve changes when prevailing interest rates in the markets change. When the yields on bonds change by the same magnitude across maturities, we call the change a parallel shift.
Alternatively, when the yields change in different magnitudes across maturities, the resulting change in the curve is a non-parallel shift.
A non-parallel change in interest rates may lead to a negative or positive butterfly, which are terms used to describe the shape of the curve after it shifts. The connotation of a butterfly is given because the intermediate maturity sector is likened to the body of the butterfly and the short maturity and long maturity sectors are viewed as the wings of the butterfly.
Positive vs. Negative Butterflies
The negative butterfly occurs when short-term and long-term interest rates decrease by a greater degree than intermediate-term rates, accentuating the hump in the curve. Conversely, a positive butterfly occurs when short-term and long-term interest rates increase at a higher rate than intermediate-term rates.
Put another way, medium-term rates increase at a lesser rate than short- and long-term rates, causing a non-parallel shift in the curve that makes the curve less humped—that is, less curved. For example, assume the yields on one-year Treasury bills (T-bills) and 30-year Treasury bonds (T-bonds) move upward by 100 basis points (1%). If during the same period, the rate of 10-year Treasury notes (T-notes) remains the same, the convexity of the yield curve will increase.
Buying the Belly of the Butterfly
A common bond trading strategy when the yield curve undergoes a positive butterfly isto buy the "belly" and sell the "wings." This simply means that bond traders will sell the short- and long-term bonds (the wings) of the yield curve and buy the intermediate bonds (the belly) at the same time. The traders expect the middle portion of the curve to rise faster because intermediate-term rates increase relatively faster than rates on the other two groups of bonds.
In reality, bond traders will factor in many variables when strategizing buy and sell orders, including the averagematurity dateof bonds in their portfolio. But the shape of the yield curve is nonetheless an important indicator.
It may generate a stable income and reduce the risks as much as possible compared with directional spreads, using very little capital. What is the success rate of the iron butterfly strategy? There is a 20% to 30% probability of an iron butterfly achieving any profit. It makes an entire profit only 23% of the time.
A positive butterfly is a non-parallel yield curve shift that occurs when short- and long-term interest rates shift upward by a greater magnitude than medium-term rates. This shift effectively decreases the overall curvature of the yield curve.
The risk of the strategy is constrained to the premium required to obtain the position. The difference between the written call's strike price and the bought call's strike price, less the paid premiums, is the maximum profit. That is why the butterfly strategy success rate is good.
A long butterfly spread is a debit spread, and involves selling the ”body” and purchasing the “wings,” and can be implemented using either all call options or all put options. A long butterfly produces its maximum profit when the underlying expires right at the middle strike price.
One strategy that is quite popular among experienced options traders is known as the butterfly spread. This strategy allows a trader to enter into a trade with a high probability of profit, high-profit potential, and limited risk.
The most successful options strategy for consistent income generation is the covered call strategy. An investor sells call options against shares of a stock already owned in their portfolio with covered calls. This allows them to collect premium income while holding the underlying investment.
A butterfly spread is an options strategy that combines both bull and bear spreads. These are neutral strategies that come with a fixed risk and capped profits and losses. Butterfly spreads pay off the most if the underlying asset doesn't move before the option expires.
Generally speaking, butterflies are composed of bonds with three different maturities: short, medium and long. The investor goes long on the short and long-term bonds (which form the barbell, or the wings), and goes short on the medium-term bond (the bullet, or body), or vice-versa.
A butterfly spread represents a strategy that's unique to option trading. The most basic form involves buying one call option at a particular strike price while simultaneously selling two call options at a higher strike price and buying one other call option at an even higher strike price.
A Bull Call Spread is made by purchasing one call option and concurrently selling another call option with a lower cost and a higher strike price, both of which have the same expiration date. Furthermore, this is considered the best option selling strategy.
The butterfly strategy involves buying an option with a higher strike price and another option at a lower strike price. The investor must also sell two options with strike prices in the middle of the earlier two options. The idea is to restrict the risk and create more chances of profit with the help of spreading.
What Is the Riskiest Option Strategy? Selling call options on a stock that is not owned is the riskiest option strategy. This is also known as writing a naked call and selling an uncovered call.
The primary disadvantage of the butterfly spread is the possibility that the market could move sharply in either direction to incur a loss on the position, and the potential trading costs versus the limited profit potential (see sidebar).
This means that the price of a long butterfly spread falls when volatility rises (and the spread loses money). When volatility falls, the price of a long butterfly spread rises (and the spread makes money). Long butterfly spreads, therefore, should be purchased when volatility is “high” and forecast to decline.
From a basic standpoint, a butterfly spread involves buying call options at a specific strike price, while simultaneously selling call options at both a higher and lower strike price.
Although small things can have a large impact, it is difficult, if not impossible, to accurately predict the relationship between small actions and effects. As we have mentioned, the butterfly effect does not mean that small things will necessarily lead to large consequences, but that they equally could or could not.
In finance, a butterfly (or simply fly) is a limited risk, non-directional options strategy that is designed to have a high probability of earning a limited profit when the future volatility of the underlying asset is expected to be lower (when long the butterfly) or higher (when short the butterfly) than that asset's ...
The max profit is equal to the strike of the written option, less the strike of the lower call, premiums, and commissions paid. The maximum loss is the initial cost of the premiums paid, plus commissions.
