Ini hari Jumat. Pembakaran theta pada opsi mingguan selalu menjadi sesuatu yang harus diperhatikan dengan cermat. Bagi siapa pun yang memegang premi pendek hingga penutupan, bagaimana Anda menyesuaikan ukuran posisi Anda untuk memperhitungkan potensi ayunan di akhir hari?
For me, it's about setting hard stop-losses. I size based on my maximum acceptable loss for that specific trade, regardless of the day of the week. Friday just means I'm extra vigilant.
I actually don't mind holding some short premium into the close on Fridays, assuming the underlying is stable and IV isn't through the roof. The decay can be quite nice if you pick your spots carefully.
Definitely. I try to keep my weekly premium positions small enough that a sudden swing won't blow up the account, but large enough to make the theta decay worthwhile. It's a tricky balance.
Definitely. I've found that cutting down position size significantly on Friday afternoons for weekly shorts helps mitigate a lot of that late volatility risk. Are you typically closing or just reducing?
Always a tricky balance. I usually scale back my position size significantly on Fridays, especially if it's been a volatile week. Better to leave some on the table than get crushed by a late swing.
