Investing in ETFs

My foray into U.S stock market started in 2022 when I signed up for Moo Moo.
Not knowing which stock to invest in, I decide to go for index ETF for a start since ETFs can be a low cost and inexpensive way to gain access to broad spectrum of stocks spanning different sectors, industries and geographical regions.
My pick then was VOO, it has helped to generate better and high returns through a basket of stocks, enabling diversification on my portfolio of safe assets in cash, money market funds, Tbills etc.

Looking for growth stocks was next on my radar,  and tech stocks being the rage then, has me embarked on TQQQ (triple returns or risks). I also sold covered call on TQQQ to generate some additional returns.

For newbies, anyone not knowing where to start or stock to pick, or not having the time to conduct research on companies, investing in ETFs tracking the index is a good way to add to your portfolio, the market will self adjust to add new counters that make the grade and drop off those lack lustre ones.
