I am new to writing covered calls and would like someone to offer some education to me. I purchased 100 TIE on 11/29/05 for 60.75 and sold 1 dec 60 for 3.50 expecting about 4% return for 19 days. Stock closed today @68.99.Dec 60 call at ask 9.50. Would it be advisable to roll up to a Dec 65 (bid 5.10),roll up to Jan 65(bid 8.00)or just sit tight and more than likely have the stock called for my 4% gain? What is the best strategy for roll-ups? Thanks in advance.
