Editing Conglomerate (company) (section)

===Mutual funds===
With the spread of [[mutual fund]]s (especially [[index fund]]s since 1976), investors could more easily obtain diversification by owning a small slice of many companies in a fund rather than owning shares in a conglomerate. Another example of a successful conglomerate is [[Warren Buffett]]'s [[Berkshire Hathaway]], a [[holding company]] which used surplus capital from its insurance subsidiaries to invest in businesses across a variety of industries.
