Handling $1.5 million in cash to maximize returns requires careful consideration of your financial goals, risk tolerance and time horizon.

Here are some possible options: 1. Invest in the stock market: Consider investing some of your cash in the stock market.

You can choose to invest in individual stocks or invest in stock funds.

Stock market investments generally have higher potential returns, but they also come with higher risks.

2. Invest in real estate: Buying a property, especially a rental property, can provide you with steady cash flow and capital appreciation.

3. Bond market: Buy government bonds or corporate bonds, which can provide relatively stable returns, especially for investors with low risk tolerance.

4. Invest in Internet financial products: Consider investing part of your funds in high-yield savings accounts, debt crowdfunding or other Internet financial products.

5. Diversify: Create a diversified portfolio that spreads funds across different asset classes to reduce risk.

6. Consult a financial advisor: If you are not sure how to invest, consider consulting a professional financial advisor who can provide personalized advice based on your specific situation.

No matter which investment method you choose, adequate research and risk assessment are required.

Also, make sure you have enough emergency reserve funds to cover unexpected expenses.

Most importantly, set clear financial goals so you can measure the success of your investment.
