Am I over diversifying my portfolio? ›

Over-diversification occurs when each incremental investment added to a portfolio lowers the expected return to a greater degree than the associated reduction in the risk profile.

If you have many mutual funds under one investment style, your portfolio is over-diversified. This increases your risk as well as investment costs. Having too many individual stock options is another sign. This will require you to constantly review and monitor your investments.

A stock portfolio focused on dividends can generate $1,000 per month or more in perpetual passive income, Mircea Iosif wrote on Medium. “For example, at a 4% dividend yield, you would need a portfolio worth $300,000.

At the same time you're compounding risk, over-diversification can dilute returns, because if you have too many investments, the positive contribution of one won't be big enough to have an impact.

In your existing portfolio, every time a new script is added, it lowers the risk of the portfolio to a very small extent.
