Topic: HOW TO TRADE IN RISING PREMIUMS SCENARIO

Option sellers specially Straddle sellers feel that rising premiums give them excellent opportunity to make easy money. So what they are seeing is the theta aspect of options & ignoring the delta/gamma/vega forces.

1/

With rising premiums come high delta moves. There is a reason why premiums are all increasing up in the first place. High uncertainty & fear is what's controlling the markets during such times. So a volatile 200 point move in nifty is always on the cards.

2/

Adjusting during such delta moves involves high slippages. Such costs go in our system & are irrecoverable. So if the ATM straddle is around 400 & after 200 point downmove, the next straddle is at 450 & the loss is not just 50points but compounded much more.

3/

Also there are chances that there is no decay throughout the day. So a straddle seller has to take that heavy risk of carrying it forward & chances of gap openings are high during such times. If converted into Ironfly, then the cost of the wings is too expensive.

4/

Thus cutting down the initial credit significantly.

There will also be very few instances when premiums don't fall till expiry day. So with each delta move the cost of holding a straddle gets accumulated & pressure keeps mounting for the stubborn option sellers.

Understanding HIGH & LOW VIX

VIX at 16: If you check today's IV behaviour, they were not spiking much even with decent delta move in BNF. The movement was subtle, giving some time to adjust. So someone having good adjustment mechanism can stay in the game longer.

1/

VIX at 20: The same delta move will be more fierce, coupled with rise in premiums. When premiums rise with movement, then the adjustment cost increases exponentially. The premiums can fall back at EOD, but the damage is done if caught in the spike.

2/

After talking to few traders, their backtest result was in favor of high VIX of 2020, rather than 2017-19. The key flaw in the backtest were the adjustments which are not easy to calculate. Combination of high theta & fixed SL during high VIX, the IV crush is cashed at EOD.

3/

Neutral option sellers who don't adjust & have fixed SL on a static straddle will not be able to benefit highly in low VIX. The straddle which moves away from ATM will increase no matter what. But if we keep on rolling our strikes, then we get good realisation of theta.

4/

I have made majority of my profits in option selling when VIX was at 13-15, mostly just relying on my adjustments. Since 2020 with high VIX, adjustments stopped working because of increase in the frequency of delta + IV spike combos & so had to shift to directional trading.

10 mistakes in my 14 years of trading as an option seller 🧵

1. Staying neutral all the time. Majority of the years i have been a neutral option seller. I now realise that having a little sense of direction would have given me an added advantage with better utilisation of capital & also leverage (till the time it was available).

2. Too much importance on adjustments. Initially like most of the new option sellers, i had this notion that i can perfect my adjustment skills for any market conditions. Ofcourse i was wrong. Market is supreme & we need to respect it at times.

3. Not giving importance to greeks. For initial 6 years i didn't even know the existence of greeks. Since i started using them, option selling has become rather less complicated on the contrary of what most people believe.

4. Having too much confidence on the certainty of theta decay. Enough is said about it already. Theta decay is not an edge.

Q: Sir why call option premiums are higher the put?

A: It usually happens when there is big difference between spot & future.

Example

BN Spot: 35110
BN Future: 35300
BN Synthetic Future: 35150

It depends on our perception of what is ATM & accordingly match the calls & puts.
