Advice on SBI, ITC

Hi,
I have following counters at following levels. I am a longterm invester and I can hold them for more than a year. Can anyone suggest me whether I should keep holding them? or whether I should avg these shares so that I can get about 20-25 % returns after 1-1.5ys time period.
Name : Price SBI : 2000 ITC : 220 Nagarjuna Fertilisers and Chemicals : 52
Thanks in advance. Parag
