like the others said, depends on its construction and materials used...

my factory string never quit giving me headaches...crept a mile and drove me nuts...i didnt know enough at the time to figure it out...just kept retuning...the shops never offered to twist the cables or check the specs and see how far out of whack they were...after going there a couple times i quickly learned how to tune myself and quit going to the shop to tune...now i know more and it could have been semi fixed, though it would still creep more..

now, my 452x string made by gibblet, i had the peep and loop put on and it NEVER moved on me. going on a year and i havent had to move anything....never had to retune...never had an issue....love it.
