With the development of economy and technology, there are more and more investment options available today. However, limited capital has always been a problem facing most retail investors. In order to optimize investment planning under the condition of minimum investment, investors need to fully understand their own risk preference, expected return and investment horizon. Proper asset allocation, choice of investment products, cost control and risk management are the key factors to consider.

Setting reasonable expectations for limited capital investment
For investors with limited capital, it is important to set reasonable expectations in terms of return on investment. High returns usually come with high risks. So chasing unrealistically high returns with small amounts of money is unlikely to work out well. Investors should set compound annual return targets of 8%-12% which are viable over the long run.
Choosing investment products suitable for small amounts
Many traditional investment products like stocks and bonds require certain account minimums. Luckily today there are more accessible options for small investments like robo-advisors, fractional shares, ETFs and mutual funds which allow easy diversification even with limited capital. These products provide opportunity for steady compounding over time.
Maintaining low costs through passive investing strategies
Investment costs like commissions and fees can significantly eat into returns on small investment accounts over time. Choosing passive investment products like index funds and ETFs which have low expense ratios is key to optimizing returns. Actively trading will also incur more transaction fees which should be minimized.
Managing risks through proper diversification
Limited capital increases the downside risks of concentrated bets. Proper diversification across different assets classes, market sectors, geographies and companies is essential to reduce portfolio volatility and drawdowns. Periodic rebalancing also helps lock in gains and maintain target allocations.
In summary, with thoughtful planning, diligent research and discipline, it is possible to achieve viable investment returns over the long run even starting with limited capital. The keys are setting reasonable expectations, choosing suitable investment products, minimizing costs and managing risks through prudent diversification.
