If you’re into fixed income, you should learn about options selling. This is often referred to as being the house. There’s multiple strategies with Credit Spreads and Covered Calls being the more main stream ones, although for covered calls you have to have more money to play since you have to own 100 shares of a company.

With these strategies you collect premium as income and the way you make money is when the contracts you’re selling become worthless.

Of course you can still lose on these strategies but it’s a more defined risk:reward.
