I bought a call option on stock xyz on 11/1/2010. On 12/1/2012, I exercise the call option to buy the stock. The call premium that I paid is added to the cost basis of the stock.
Does my holding period for this stock starts on 12/1/2012 (date of exercising the call option)? Or 11/1/2010 (date I acquired the call option)?
TIA.
