a forummer "Vanguard 2015" once highlighted this overlapping called "Diworsification"
http://www.investopedia.com/terms/d/diworsification.aspQUOTE
The process of adding investments to one's portfolio in such a way that the risk/return trade-off is worsened. Diworsification is investing in too many assets with similar correlations that will result in an averaging effect. It occurs where risk is at its lowest level and additional assets reduce potential portfolio returns, as well as the chances of outperforming a benchmark.
The term was coined by legendary investor Peter Lynch in his book, "One Up Wall Street," where he suggested that a business that diversifies too widely, risks destroying their original business, because management time, energy and resources are diverted from the original investment.
Very confusing explanation by Investopedia
Aren't 'similar correlations' and 'too widely' opposite meaning?
Let me explain... one example of diworsification is:
Sime Darby, a plantation company, diversified into banking sector by establishing Sime Bank.
As some of you probably know, Sime Darby eventually sold off Sime Bank.
OTOH, investing in funds with similar correlations (e.g. two Asia Pac equity funds) is NOT necessarily a diworsification. The key is whether those investments drain your management time, energy and resources.
