Pretty much it in a nutshell, uber low interest rates deter people from savings or cash, thus money flow into equities and tangibles like real estate or gold.
My father always had a saying, “Nothing goes in a straight line”. So yes these bull markets become bear markets and then reverse course again. Market timing is scary and even the pros dont always get it right. Be diversified. Play it a bit more safe as you age.
As for the NASDAQ or QQQ yes it is more volatile, with technology you are betting much more on innovation or things to come. In recent times, the FANG stocks have really driven this rise, but they are THE ECONOMY now. Overlay AAPL or APPLE over that chart and you will see what drives it.
I would also add that Covid on many levels has driven segments of this market. Sitting at home has driven people to even more technology, more electronic gadgets to work from home, Apple, more deliveries from Amazon and Target.
And in addition, young people seem hip on investing, they have their gadgets and apps and are adding small amounts of money to play in the Wall Street game as they see it. From Crypto trading to the REDDIT stock crowd funders and crashers... interesting times.
Agreed
