Billionaire investor Bill Ackman's plans to turn real estate company Howard Hughes Holdings into a diversified holding company will not impact how his investment portfolios buy and sell stakes in companies.

Ackman has for months been pursuing Howard Hughes in a bid to create the next Berkshire Hathaway.Berkshire Hathaway was a textile company when Warren Buffett acquired it in 1965. The legendary investor and his partner Charlie Munger merged two other companies — Diversified Retailing and Blue Chip Stamps — with Berkshire in 1978 and 1983 before closing the textile firm's failing business in 1985.

The deal would give hedge-fund manager Bill Ackman’s firm a 48% stake in the company known for master-planned community developments.
