Do you guys know much about these? Are there stocks or bonds?
I know its probably a stupid question, but I am really dumb when it comes to things like that.
Ive been investing in S and P 500 for a long time and that's the only thing I know, but want to learn more about other ones...
The S&P 500 is a large cap index, so it sounds like you don't invest in the Russell 2000 - a small cap stock index. $RYLD holds the Russell 2000 while using an options strategy to try and make extra money. I would not recommend a novice investor start with options strategies.
In general, "covered calls" earn bond income when stocks fall or go nowhere - they will do well at those times. The stock market, however, has very volatile upwards gains during recoveries and surprises - and "covered calls" lose all of that upside. The "call" sells the upside to someone else. You lose big gains in exchange for small dividends.
In Nov 2020, $RYLD gained +8% with an extra +1% in dividends, which sounds like a great monthly return. But it is a covered call strategy on the Russell 2000 ($IWM), which gained +17% that month.
If you are looking to diversify, I'd suggest a look at your stock/bond mix before checking out options strategies.
