It is recommended to continue holding it. First of all, if you want to arbitrage, you must redeem it when the economy is good at 20 10. Even at 10, the final net unit value is only about 1. 1. At that time, we also lost money, just a little less.
Don't redeem the money unless it is urgent. Lost nearly half. Why are you still redeeming? This does not include inflation.
If you are optimistic about this fund. Have knowledge in this field. Then buy another 20 thousand. Share the risk equally. Personal advice. I hope I can help you. . .
