Quote from rmorse:
Most can be borrowed. You will require a locate on any of them, not on the easy to borrow list. Most require locates and have negative interest rates. If you're just day trading, you only need the locate. The negative interest rate is not an issue.

@churchill I did this exact trade a few years ago. logistical nightmare having to rebalance the sides daily. Profits were minimal and you're exposed to a black swan event (if markets drop by 25% in a day, the 3X long will go against you greater in dollar terms than the 3x short will go for you (asymptotic approach to zero)
Summary, lots of headache, minimal reward
