Curious: how do folks experienced in shares rebalance their portfolios, if at all? I know many are averse to selling, ever (eg Thornton's "If the wish to sell appears, take two aspirin and lie down") but do most folk here who are doing well periodically rebalance their portfolios? If so, how often (every 6/12 months)? Or do you prefer to just hold forever, regardless of the composition or the balance of your shares:cash(/?) ratio?
