I am somewhere in the middle between your sentiment and Srumpyjack's. I crystallised a gain several times last year as the price kept rising and my last sale was at £14.10 in February this year. I still hold more in SMT now than in January 2020, so I tend to sell to catch the rises. As it happens I would of course have been better just to have held them all but how do we know? My policy is to invest in the likes of SMT and then as gains arise sell and buy something else, usually with a decent dividend. That does two things, gives me a bit more income and a bit more diversification. I do not necessarily buy something new, it might just be a top up of one or two existing holdings.
