杠杆基金的杠杆是指数基金与债券基金的结合体，它可以通过借款等方式来放大投资收益，从而获取更高的投资回报。简单来说，杠杆基金就是通过使用借款等手段来放大投资收益，以较小的资金获得较大的收益。

杠杆基金通常采用“1+X”模式，即投资者可以通过支付一定比例的保证金来获得“X”倍的杠杆投资效应。例如，若投资者支付10%的保证金购买一只“2倍杠杆”的杠杆基金，则该投资者可以获得相当于自身投资金额两倍的投资收益。

然而，杠杆基金的投资风险也会相应放大。如果市场走势不利，投资者将面临更大的亏损。因此，在选择杠杆基金时，投资者需要对自身的风险承受能力和投资目的有清晰的认识，并选择适合自己的杠杆比例。

The leverage of a leveraged fund refers to a combination of index funds and bond funds, which can amplify investment returns through borrowing and other means to obtain higher investment returns. Simply put, leveraged funds use borrowed funds to amplify investment returns, allowing smaller funds to obtain larger returns.

Leveraged funds typically adopt a "1+X" model, which allows investors to obtain "X" times the leveraged investment effect by paying a certain percentage of margin. For example, if an investor pays 10% of the margin to purchase a "2x leverage" leveraged fund, then the investor can obtain investment returns equivalent to twice the amount of their own investment.

However, the investment risk of leveraged funds will also be amplified accordingly. If the market trend is unfavorable, investors will face greater losses. Therefore, when selecting a leveraged fund, investors need to have a clear understanding of their own risk tolerance and investment goals, and choose a suitable leverage ratio for themselves.
