When you do tend to hold then you should really be having that strong will that you should stick into it no matter what happen or the condition of the entire market specially when theres some dump or crash
then its just impossible that there wont be any tingling feeling for you to consider on having a sell to cut loss but if you do have already fixed up your mind on something like this then you wont
really get surprised but instead you would really be seeing rather an opportunity for you to enter since everything is cheap.
