Unit 2 · Level 2 · Diversification
Diworsification
Legendary fund manager Peter Lynch coined the word 'diworsification': adding holdings that add complexity, not protection. Picture an investor proudly holding 40 funds: a 'World Tech Leaders' fund, a 'Digital Innovation' fund, a 'US Growth' fund... open the fact sheets and the top holdings are the same handful of mega-cap names, over and over. Forty tickers, one bet.
Free to play. No ads, no token, no account needed to start.
What you get asked
Jonas owns 12 different technology funds. How diversified is he?
Diversification lives in the underlying holdings, not the number of wrappers. Twelve overlapping tech funds ride the same wave up and the same wave down.
What determines how diversified your portfolio really is?
Look through the wrapper to the ingredients. Two funds with different names and identical top-10 holdings are, for risk purposes, the same fund.
Owning many funds with the same top holdings adds ___, not diversification.
Extra funds mean more fees, more admin, and more tax paperwork, often with zero extra protection. Diworsification is effort spent making a portfolio worse.
Put the overlap check in order
Ten minutes with fact sheets tells you more than any fund name. Most 'complicated' portfolios simplify into one or two broad funds without losing anything but fees.
What's the simplest genuinely diversified core for a long-term stock portfolio?
One boring global fund out-diversifies a drawer full of theme funds: every country, every sector, one low fee. In diversification, ingredients beat packaging. 🐜
