Can an overly diversified stock portfolio hurt you?
Too much diversification can make a portfolio worse
Diversification Can (Potentially) Lower Returns
Thus, diversification may cause an investor to miss out on the potential high returns of a specific stock, asset class, or market segment that is outperforming.
Can you over-diversify a portfolio? Yes. Holding 50 stocks rather than 25 may lower your downside risk somewhat, but it can also reduce your profit potential. And at that point, it may be better to consider investing through an index fund, or even a combination of several sector-based funds.
The only risk affecting a well-diversified portfolio is therefore systematic. As a result, an investor who holds a well-diversified portfolio will only require a return for systematic risk. In this article, we explain how to measure an investment's systematic risk.
However, too much diversification can be considered a bad thing and lead to diworsification. Just like a lumbering corporate conglomerate, owning too many investments can be confusing, increase investment costs, add layers of required due diligence, and lead to below-average risk-adjusted returns.
Diversification is not without challenges and drawbacks, however. It can also expose you to several risks, such as losing focus, diluting your brand identity, increasing your costs and complexity, facing more competition, and failing to meet customer expectations.
This would be your interest-based return if you built a 100% bond portfolio overnight. In the long run, if you were to only invest in AAA corporate bonds over time, you can expect a modern yield between 4% and 5%.

It's a good idea to own a few dozen stocks to maintain a diversified portfolio. If you load up on too many stocks, you might struggle to keep tabs on all of them. Buying ETFs can be a good way to diversify without adding too much work for yourself.
Overdiversification happens when the number of investments in a portfolio exceeds a point where the marginal loss of expected return is higher than the marginal benefit of reduced risk. In your existing portfolio, every time a new script is added, it lowers the risk of the portfolio to a very small extent.
Too many stocks can often lead to fewer gains, according to his experience. Cramer learned this lesson while working at his hedge fund years ago. He observed that his portfolio's performance was linked to the number of stocks he held. The fewer stocks he had, the more money he made, Cramer said.
What is considered a well diversified portfolio?
A portfolio that includes a variety of securities so that the weight of any security is small. The risk of a well-diversified portfolio closely approximates the systematic risk of the overall market, and the unsystematic risk of each security has been diversified out of the portfolio.
Which stock is riskier for a diversified investor? For diversified investors the relevant risk is measured by beta. Therefore, the stock with the higher beta is more risky.
The main problem is that an asset does not necessarily suit their goals just because it is familiar. Keeping loyalty to one or several stocks could make their portfolio undiversified. Financial theory says that before making any trades, you should carefully weigh up the potential risks and returns.
Financial-industry experts also agree that over-diversification—buying more and more mutual funds, index funds, or exchange-traded funds—can amplify risk, stunt returns, and increase transaction costs and taxes.
Assuming you do go down the road of picking individual stocks, you'll also want to make sure you hold enough of them so as not to concentrate too much of your wealth in any one company or industry. Usually this means holding somewhere between 20 and 30 stocks unless your portfolio is very small.
Key Points: Concentration risk is usually defined as having more than 10-15% of your portfolio invested in a single position.
But while diversification as a strategy can reduce risk, it can also introduce significant new risk, because it can take a corporation away from its core competences .
Over diversification is possible as some mutual funds have to own so many stocks (due to the large amount of cash they have) that it's difficult to outperform their benchmarks or indexes. Owning more stocks than necessary can take away the impact of large stock gains and limit your upside.
More focused companies are often easier to manage and possess a clear, strategic goal – something that can be lacking with diversified firms. “One of the main reasons that diversification fails is because businesses do not have the right strategy in place,” Shipilov said.
