Diversify, But Don’t Overdo It

 


A Coffee Table Conversation - Disadvantages of Diversification

It was a relaxed Sunday evening. Four cousins - Aditya, Priya, Ria, and Rohan -had reunited after months. Over coffee and laughter, the conversation drifted from old memories to new-age investments.

“You guys won’t believe how many stocks I hold now,” Rohan said, proudly sipping his cappuccino. “Last count - 52!”

“Whoa,” Ria raised an eyebrow. “Are you running a mutual fund or what?”

They laughed, but Aditya leaned in. “Rohan, that sounds like over-diversification to me. You might want to rethink it.”

“Wait, I thought diversification reduces risk?” Rohan asked, confused.

Priya nodded, “It does - but only to a point. Go beyond that, and it starts working against you.”

“How so?” Rohan asked. And so began a mini masterclass.

1. Diluted Investment Quality

“Think of it this way,” Aditya explained. “There are only so many genuinely great companies out there. If you own too many stocks, you’ll inevitably include mediocre or poor-quality ones. That dilutes the impact of your best picks.”

Rohan frowned. “Makes sense. I did buy some stocks just to ‘fill out’ sectors.”

2. Portfolio Becomes Unmanageable

Ria jumped in. “And with so many holdings, can you really track them all? News updates, earnings reports, business changes... it's exhausting. A bloated portfolio often means less control and more stress.”

Rohan chuckled nervously. “I’ve definitely lost track of some of them.”

3. You May Just Be Mimicking the Index

“Here’s the ironic part,” Priya added. “If you’re spread too wide, you might as well have bought an index fund. But you’re paying way more in brokerage or fund fees and putting in more effort. It’s like paying extra to manually replicate what a single fund could do.”

“That stings a bit,” Rohan admitted.

4. Subpar Returns

“And let’s talk returns,” Ria said. “If you mix high-quality stocks with weak ones, your overall performance suffers. It’s like mixing gourmet coffee with instant powder -you ruin the flavor.”

“Not to mention the emotional side,” Aditya added. “When markets fall, people panic. With too many investments, it’s harder to know what to sell or hold. So they sell the winners and hold the losers - classic mistake.”

5. Lack of Personal Oversight

Priya nodded. “And if you rely too much on mutual funds or managers, you stop paying attention. One bad quarter, one shift in market trend -and you’re the last to react.”

Rohan leaned back, thoughtful. “So you’re saying - less is more?”

“Not zero diversification,” Ria clarified. “Just strategic diversification. Hold enough to manage risk, but not so much that it becomes clutter.”

“There are several other downsides,” Aditya added, “but these are enough to rethink our approach.”

As the coffee cooled and laughter resumed, Rohan made a mental note to review his portfolio that night.
