Equity put option written

The previous put option I had written against the HK Tracker Fund (2800) expired without being exercised and I pocketed the premium.

Yesterday I wrote another one month put option against the HK Tracker Fund at a strike price of HK$14.42 per unit (the market price was HK$15.32 at the time). The annualised yield is about 15% (assuming the option is not exercised).

Whil I have made money on all my option trades this year, given the extent of the market's advance, I would have made more money by simply buying the underlying.
