Do you factor in margin, either reg t or portfolio, when considering what size to put on? What other etf options do you look at?
Quote from KINGOFSHORTS:
If you are unwilling to be assigned. DO NOT SHORT OPTIONS CONTRACTS.
Assignment is part of the buisness.
I get assigned.
I sell options on the index etfs. but I always factor in assignment risk.
This means.
#1 You must have enough capital to take stock when assigned.
#2 You must use funds you are willing to have tied up for trading.
Selling options on the SPY ETF is a pretty conservative way of going about it. But only do it if you can take the stock.
For example you might sell the SPY 117 strike for november (which I did) for 2.25 a contract. (85 contracts)
November comes SPY plummets to 107.50 . Lets say you get assigned.
now you have SPY on your account you paid 115.25 but your underwater by 7.75 points.
Now you have to sit on your hands and wait for it to go back up, Sell deep OTM calls for the next month or sell and take a loss.
You need to think this ahead of time before you do your trade.
Your thought process should be before entering a trade.
#1 Take into consideration assignment risk.
#2 Plan accordingly when assigned. What is your plan?
#3 execute your plan.
Options is not daytrading, it is a slower process and more planning involved. It can be quite profitable but it requires lots of thinking before the trade.
Also Options trading is pretty capital intensive. I primarily sell short IWM and SPY puts and calls(covered) but I maintain a large cash position and a large underlying inventory of both etfs.
I want to add that BS or Binomial options pricing is just a "Ruler" to measure.
Just like using a ruler to tape measure an individual for a suit. You might measure them at 36 but that does not predict anything, what if over the weekend the individual got Cholera and now measures 34 inches?
The tape measure did not predict cholera.
The tape measure (BS or Binomial) is just a tool to let you measure the option and then use the measure ments to calculate how pricing impacts the movement of the options pricing movement.
So you can say if the options delta is .50 that means one short put is the equivalent of 50 shares of the underlying. And you can then say, okay if the underlying goes down one point the options price will move .50 up or down.
where then gamma lets you determing how the movement of the underlying 1 point how does this now effect the delta. So if Gamma is .10 then if the stock moved 1 point now the delta is .60
Anyhow. It is good you are chosing SPY for your underlying.
Too many fools chase single stocks with high IV's for options writing only to be wiped out.
:eek:
