I've got a 1.5x leveraged portfolio over on IBKR that is currently yielding ~2.9% dividends across a wide range of sectors. I am paying ~1% in margin fees at the moment, so I basically get to use their money for "free" on the growth side (of which there is plenty right now). It is turning into quite the comfortable safety blanket.
I almost feel like this is not in the spirit of the topic posed here because of how mundane and uninteresting stock investments are, relatively speaking. I am far more interested in reading through all of the tales of crazy side projects that have turned into something more.
