I am planning to trade a small fund (US$ 1m) focusing on HK stocks, long/short. Stamp duty in HK is very high 10bps, but its a govnerment thing, gotta suck it up. The thing is I find the borrow costs there quite high, often in mid 10%. Is it common ? How can I carry shorts for a few months being charged that kinda rate. Do you guys encounter the same issue?
