If the loss of buying a fund is too large, you can appeal, and the court will determine the sharing of the loss as appropriate. The seller of the fund bears the investor's obligation of appropriateness in the sales process, that is, selling the appropriate products to the appropriate customers, and undertaking the obligation of reasonable recommendation and appropriate sales. The core content includes knowing customers, knowing products and selling properly. If the seller fails to do this, or there is no evidence to prove it, it is that there is a fault in the buyer's investment loss and he should be liable for compensation.
