Yes, it is perfectly acceptable to have a straightforward portfolio. A simple portfolio can actually be advantageous for several reasons. Firstly, simplicity in a portfolio often makes it easier for an individual to manage and understand. This can reduce stress and the likelihood of errors that might come from overly complex strategies.

Secondly, a simple portfolio typically has lower fees and transaction costs. With fewer trades and the use of low-cost index funds or ETFs, investors can reduce the friction that eats into returns over time. This approach also aligns well with many modern investment philosophies, which advocate for long-term holding of diverse, broad-market funds.

Additionally, a simple portfolio is easier to monitor and rebalance, which helps maintain the desired asset allocation through different market cycles. This consistency can be a major factor in achieving long-term financial goals.

Moreover, empirical evidence suggests that simple portfolios often perform as well as, if not better than, more complex ones. The added complexity doesn’t always translate into better returns, and it can divert focus from important factors like asset allocation and risk management.

Lastly, a simple portfolio caters to the principle of minimalism by focusing on what is most important and disregarding noise, thus contributing to a more focused approach to investing.

In conclusion, a simple portfolio can suit a wide range of investors, particularly those who value clarity, cost-efficiency, and a long-term perspective.
