Short gamma

The gamma of every option is either a positive number or it is zero. If you do not know what gamma is, check out this article. So if we buy options that have a non-zero gamma, we will be long gamma. Whereas if we sell options that have a non-zero gamma, we will be short gamma. And the bigger the price movement, the better.

For a short gamma position, the exact opposite is true; movement in the spot price is bad. The bigger the move, the worse it is. Gamma is the change in option delta for a change in the price of the underlying. If we are long gamma with a delta-neutral options book it means that if the spot price increases, our delta will start to increase. If the spot price rallies and we are long gamma, we become longer delta. Delta can be seen as our equivalent position in the underlying via our options portfolio; hence we are becoming longer the underlying product via our options.

We own something whose value is increasing. Good news. Starting from first principles, option gamma is explained in straightforward English before separate sections on gamma hedging, gamma trading and advanced gamma trading […]. Now with long gamma, the spot price falling is also good news. As the spot price falls, our delta changes from neutral to becoming negative. This is good news because we are short when the price is dropping. Not good in a rallying market. Likewise, if the spot price falls from the starting point of delta-neutrality, the short gamma leads to the position delta becoming positive; getting long the spot product as its value drops.

The change in the delta is equal to the gamma multiplied by the change in the spot price:. So if long gamma makes money from a move in any direction and short gamma always loses money, why not always be long gamma? Well there is an extra factor to consider. As time passes, the optionality of options decays.

Longer dated options are more valuable than short dated options, other things being equal. In other words, there can be a cost associated with owning options.Long gamma traders want the stock to continue trending in the same direction.

Author, Options Volatility Trading. I often mention the option Greek gamma, and refer to "long gamma" or "short gamma" when describing a position. So I'll explain. Gamma is used to measure the rate of change in an option's delta as the underlying security stock, ETF, index moves.

In a positional context, long gamma means your option position is such that if the stock rallies or declinesyour share equivalent position also known as delta gets you longer or shorter. That means that each put you own is the equivalent of being short 50 shares of stock.

So, right here, right now, owning 20 puts is the share equivalent of shorting 1, shares of AAPL. But let's say AAPL rallies. The share equivalent delta position of my puts declines. For arguments sake, let's say they now have 40 delta, making me equivalent to short shares via the puts 40 x My stock position obviously stays the same at 1, shares, making my net position the equivalent of long AAPL shares 1, - That's a long gamma position.

Sounds great, right? Stock rallies and I get longer; stock declines and I get shorter. Who wouldn't want that? I can sell AAPL into rallies and buy it on declines, and not have to worry about being wrong. If it rallies more, I can just sell more! But remember, this sort of position costs money each day. Options are a decaying asset. The less time remaining until expiration, the lower the value of an option, all else being equal.

Another option Greek, theta, measures your daily decay. And that's your cost of holding a position like this in Apple. For this particular example, let's assume the volatility of the option remains static.

In order to earn money on a long gamma position such as this, we need to offset our daily decay. One is to aggressively trade AAPL stock and hope to earn enough "flipping" to offset the cost of the position. Remember that you get longer as it goes up and shorter as it goes down. It's the equivalent of trading with a safety net, so you're literally able to trade against every move up until you've bought sold 1, more shares. The higher above or the lower below those levels, the more you win.

For example, you'll likely sell some into strength and leave some. You'll get lucky sometimes and wake up to gaps in AAPL. You'll get unlucky sometimes and have AAPL stick near the strike for long stretches of time. Part of successfully managing a long gamma position involves making judgments as to whether we're in a "trend" environment or a "range" environment.

If it's a range day, week, or month, then you really need to get in there and flip the stock on any "noise. Tech remains the most interesting sector when it comes to unusual options activity.

When the stock price increases, gamma is added to delta. Conversely, gamma is subtracted from delta when the stock price decreases.

This is due to the fact that they are long gamma. Being short gamma would mean that the exposure to the underlying becomes more long as the underlying price drops and more short as the underlying price rises. Also, for a market maker in the option market, writing selling an option means being short gamma, so if there is no counterparty willing to be short gamma, how are they going to hedge their gamma? Being short gamma simply means that you are short options regardless of whether they are puts or calls.

The most common type of investor that is willing to be short gamma is someone who sells options, also known as a premium collector.

Clearly there is significant risk associated with a probability of success that high, so approach with caution. You are absolutely right to point out that most proactive participants in options markets prefer to be long gamma, and it is typically reactive market makers who take the opposite side of their trades.

While the typical options trader I find it difficult to call anyone trading options an "investor" does not hedge his position, market makers will attempt to dynamically hedge an entire portfolio of options. In addition, covered call writers also known as call overwriters are a major source of gamma to the market, particularly for individual stocks.

Failing that, some more sophisticated market makers, or market makers in less liquid options, will put on an inexact hedge using options on a closely correlated underlying with more liquid options, or with ETFs or index options. Market makers are typically paid for this service via the negative volatility risk premium see Bakshi and Kapadia [a]. However, partly due to the influence of call overwriting, which is more common for individual stocks, and partly due to the ability to diversify away some idiosyncratic volatility, the volatility risk premium is much greater in index options see [Bakshi and Kapadia b ].

Some active options traders also attempt to exploit this difference via dispersion trading. Short gamma is being of the view that realized volatility would be less than the implied volatility for the period in which an option is valid. So if you think realized volatility in the future would be consistently lesser than implied volatility at present, then you'd be short gamma. The premium one would receive by selling an option call or put is a proxy for the implied volatility of the underlying forward underlying, to be precise, if you take into account stochastic discount rates.

As Australians it was a memorable holiday. The maps have been great - very well prepared with and in combination with the daily itinerary we did not miss one thing on the way. Overall great service and amazing experience in Iceland. Intentionally we did not book the cheapest tour, but we have been surprised by the above standard for accommodation and customer service.

The island itself is breath-taking as long as you can stand the climate changes (which shift often :) Looking back I do not regret going to Iceland.

The maps and other written materials provided were very helpful. Accomodation was excellent, friendly and in good locations. This was a great vacation. The service from Nordic Visitor excellent. The emergency updates regarding potential disruption due to volcanic activity were very much appreciated and demonstrated excellent customer service.

Thank you for making our first trip to Iceland one of hopefully many more. Our trip was well-planned and we had all the information we needed to make it hassle free from the different connections throughout the countries we traveled.
