Full disclosure that I got this one wrong the first time too. Being able to leverage the position means greater return on equity, which is an advantage. Or think about your own life, if you want to go buy a house, its a good thing to be able to get a mortgage so you can decrease your initial outlay, right?
2008 Financial Meltdown … was why?.. simply put “leverage” but CFAI says it is an advantage then that is what you answer with… Guess as long as you earn more on it than cost of borrowing then absolutely makes sense but as long as you can afford the leverage
