I have changed my strategy few times… what’s also OK, the more you learn, more you do improvements on any area of your live.
My latest strategy version is very simple:
For blue chips/dividends/etc: I have some historical timeframe targets, like 5Y, 10Y 15Y and 20Y, if a stock has beaten S&P500 in 3 out of these 4 targets, considering reinventing dividends, then I hold it separately, otherwise I will stick to VUSA/QQQ.
Exceptions: Stocks that I manage to buy very low and mighty give a mid-term (at least) return above the market.
Growth: Any company with very good growth potential that are solid already and kind of leader (or almost) in any segment. e.g. Apple, Microsoft, Tesla, AMD, Nvidia, Nee, etc.
ETFs: some for diversification and heavily on VUSA/QQQ.
The rest goes all to Nikola
