Quote from vanv0029:
I have been using the idea of selling ATM
straddles as a way to add to stock positions
at a good price (the bottom of the current
trading range. Idea is to sell the near month
ATM straddle just after the previous month's
expiration with the hope that the price will
fall and the shares will be put to me.
The approach does not need falling IV
but relies on theta decay. After a few weeks,
the straddle price hopefully falls from theta
decay and possibility also from falling IV.
Then, the high side calls of the iron butterfly
can be purchased if the stock has not fallen
too much. Best result is if the stock falls
below the botton break even point so the
short puts will be exercised. If near expiration
and the price is above the straddle low break
even point, then the position is closed for a
profit.
For example, I wanted to add more oil and
gas drillers in late February. On Feb. 22,
sold the OIH 140 straddle for +10.02. It
could now be bought back for -6.60 with
a good profit, but I hope OIH will fall to
130 so I am waiting. With only one week to
expiration, the 145 protective calls are only
bought if there is a very rapid rise.
IV was around 38% on Feb. 22 and is now
around 32%. Trade should not be made
if IV is historically low.
The main risk is immediate rapid price
rise before enough theta decay has occurred
for a guaranteed profitable trade. Therefore
idea works best for ETFs because of the
risk of takeovers.
I am looking at entering the same trade
using XAU probably April 127.50 straddle
around March 21 assuming IV stays around
it historical 37%. If XAU price falls as I hope,
I will buy the same dollar amount of metal
stocks since the XAU component stocks
mostly have hedged too much of their
production.
In the past, I have sold puts as a way to
enter positions, but I think selling gamma
is a much better idea.
Is there something seriously wrong with
this idea?
