If I buy a fund of 10,000 yuan, will I be the most indebted to 10,000 yuan and not lose more?

Buying a fund of 10,000 yuan is right in theory, but the probability of actual realization is almost zero. Even if the fund is chasing up and buying 10,000 yuan, if it encounters a bear market, it will be thanks to 50-60%, that is, 5,000-6,000 yuan. The fund is a stock portfolio. Only liquidation will not lead to delisting, and all losses can only be alarmist.
