Becoming an investor has many stages. One of the first is moving from high-yield savings accounts to US Treasuries.
After you get a taste of Treasuries, you may seek higher yields by investing with a little more risk.
Baby bonds sit higher on the capital stack than equity (stocks). Therefore, investors get more safety because they will get paid before stocks.
Using baby bonds and Treasuries in tandem won't be difficult because they perform well at various times. You just need to find the one that is out of favor at the moment. Good Luck!
