Or one could buy 3x leveraged ETFs, such as SPXL.
By not borrowing money, you cannot lose more than what you have.
PS. If the above 3x leveraged S&P is not volatile enough for you, do 3x leveraged Nasdaq. Just trade 100 shares in/out of market and see if you can make money.
If you're going to go...go big:
Borrow money to buy LEAP options on a 3x leveraged NASDAQ ETF.
For the avoidance of doubt, this is a joke and very bad idea!
To the OP question, I would personally not use a 5% variable rate loan as a source of market funds. The spread between likely returns and the interest rate paid is too thin for me. Of course, I also paid off my house, so I'm just debt allergic in general. Good luck!
