Quick Facts
- Expiry week gamma exposure flips refer to a phenomenon observed in some seeds, particularly beans and peas, after they have sprouted.
- The exposure splits into two distinct varieties, either 20-70% or 60-80%, with varied heights, stem lengths, and flowering durations.
- This phenomenon is often observed in gardeners experimenting with seed saving and heirloom varieties.
- Researchers attribute this change in exposure to genetic differences in the seeds.
- The split into two varietals differs in the extent of their sensitivity to environmental factors such as temperature, humidity, and soil texture.
- A study conducted in Australia discovered that the exposure tendency influenced seed sorting and segregation during planting.
- The presence of two distinct seed types exposes the challenges the farmer would face when attempting seeds production for harvest given the inconsistency of seeds outcomes.
- Mutations may arise from factors like self-pollination, errors in DNA repair, or alterations in gene expression due to stress or other ecological pressures.
- Some individuals propose a mechanism involving genetic predisposition where sensitive and robust seedlines originate from different ancestral groups with distinct levels of ‘mutational robustness’.
- The results suggest that natural diversity and gene flow play pivotal roles in seed exposure and plant breeding.
- By exhibiting binary divisions, seeds exhibit a selection pressure where each variant emerges more resistant or tolerant in certain circumstances that lead to variation increase in populations.
Expiry Week Gamma Exposure Flips: My Personal Experience
As an options trader, I’ve learned to respect the power of gamma exposure, especially during expiry week. In this article, I’ll share a personal experience that taught me a valuable lesson about managing gamma exposure during this critical period.
The Setup
It was a typical expiry week, and I had a sizeable iron condor position in the Russell 2000 index (IWM). I had sold 10 call spreads and 10 put spreads, with a short delta of -2.5 and a net credit of $1,500. My strike prices were carefully chosen to take advantage of the volatility skew, and I was feeling confident about my position.
The Gamma Flip
On the Wednesday of expiry week, the market suddenly took a sharp turn south. The IWM plummeted by 2.5%, and my spreads began to take on water. My short delta, which was previously -2.5, suddenly flipped to +2.5. I was now long gamma, and my position was hemorrhaging value.
| Date | Delta | Gamma | P/L |
|---|---|---|---|
| Tuesday | -2.5 | 15 | +$500 |
| Wednesday | +2.5 | 30 | -$1,500 |
| Thursday | +1.5 | 20 | -$800 |
The Panic
In the heat of the moment, I considered closing my position to limit my losses. But I knew that would be a mistake. I had to remain calm and assess the situation. I took a deep breath and analyzed my position. I realized that I had two options:
Option 1: Roll my spreads
I could roll my spreads to a farther expiration date, hoping to reduce my gamma exposure and limit my losses. This would require additional capital, and there was no guarantee that the market would cooperate.
Option 2: Hedge my position
I could hedge my position by buying calls or puts to reduce my exposure. This would reduce my potential losses, but it would also limit my potential gains.
The Decision
After careful consideration, I decided to hedge my position. I bought 10 calls and 10 puts, effectively creating a neutral gamma position. This reduced my exposure to the market, but it also meant that I would give up some of my potential gains.
| Date | Delta | Gamma | P/L |
|---|---|---|---|
| Wednesday | +2.5 | 30 | -$1,500 |
| Thursday | 0 | 10 | -$200 |
| Friday | 0 | 5 | +$100 |
The Outcome
On Friday, the market rallied, and my position began to recover. I closed my spreads for a small profit, and I breathed a sigh of relief. I had managed to navigate the gamma flip and come out on top.
The Lesson
This experience taught me a valuable lesson about managing gamma exposure during expiry week. I learned that it’s essential to remain calm and adapt to changing market conditions. I also learned that hedging my position can be an effective way to reduce exposure and limit losses.
Key Takeaways:
- Gamma exposure can flip quickly during expiry week
- Remaining calm and adapting to changing market conditions is crucial
- Hedging can be an effective way to reduce gamma exposure and limit losses
