For the US stock market, 70% of its rise in 2021 is attributable to a small handful of stocks ie AAPL MSFT NVDA TSLA GOOG etc. Hence the good returns for index investors in the S&P 500 and the Nasdaq. It would not surprise me if this continues to be so in 2022 as these are big liquid stocks with great sales and earnings and hence institutional favourites. Some such as NVDA and AMD look poised for even further growth if the market and Fed cooperates. The irony is that some investors don't like TSLA or AAPL yet they invest in index funds of which their performances are largely driven by these very two stocks and a few others!
Like it or not, tech is still the engine behind any long growth followed by medical/biotech and consumer brands. It's been so for the longest time and will be for the future. Hence, always look for new stock ideas in these 3 groups before others.
