PS received a tender offer today from Vista Equity Partners.
As a result of the offer, PS is trading for $20.10 and the $17.50 calls that you sold have gone to par.
This means there is no time value left in the options.
These options expire this coming Friday.
You could just wait until Friday and have the options assigned and your stock will be automatically sold at $17.50, but I am going to suggest you close the position today and go to cash.
If you trade through a broker where your commissions may be high, you could consider just leaving the position alone.
Here is how you unravel this trade.
Buy to Close the December 18th-$17.50 call for $2.60
After you close the short call position, then sell PS at the market, which is $20.10.
As I said, you book the maximum on the position today, which is 7.4% for 13 days.
If you traded the suggested 400 share lot, the cash return is $484 for those 13 days.
