<prompt> Human: My bank is offering me a loan 5 years, 4.9. I have started wondering whether it would be a good idea for someone to take a loan and invest it in funds or similar. I am instinctively against it, but Im not sure Ive examined all pros and cons. What do you think?  <response>: As someone developing an ulcer from trading with margin, Id highly recommend against it. 4.9 is pretty hefty, and a single bad market move could wipe you out. Especially if you dont have the money to cover it.
