Good morning
of course, strong buy and buy stocks are the ones I prefer to buy. There are others which I bought at the time and which have evolved into watch/hold or hold. In my opinion, these are less attractive stocks to buy at present.
But you'll probably be able to find good reasons why you think these stocks are still buying opportunities. The reverse can also be true: stocks that I consider buying opportunities may seem unattractive to you. What's important is that you're comfortable with what you're doing.
As regards the weighting of stocks, I always buy for the same fixed amount, after which it depends on price fluctuations. As I have 20 stocks in total (16 from the global dividend growers strategy and 4 from the swiss value dividend stocks), and as the stocks are not very volatile, we stay around 5% per stock.
