I did pretty much this a couple years ago for a while. It worked, it did generate some extra return, but also never anything really substantial. I stopped because the few shares (CH listed & mainly CH exposure with high dividend yield) I was doing it with became too expensive, and I wasn’t happy anymore with the downside risk. Ultimately it’s a nice idea, but you really need to understand and be comfortable with you risk profile.
Edit: I did subsequently follow-up with various methods to improve my portfolio yield and/or enhance other elements like this, but recently ended up going back to good old buy and hold and nothing else.
Tell me more?
