I'm very sure. he puts out a yearly newsletter and lists his blue chips. In early 2000 1 year before the morgage boom he purchased progressive reality of southern california which ironically was the starting point of the whole housing boom across the country. it was his blue chip year after year. Berkshire is known for buying undervalued companies and turning them around, why was this realty undervalued unless they knew the boom was coming? They have rebranded this now as Berkshire realty. I try to tell people that Buffett is a fucking scum. You don't think him and his billionaire banker friends didn't orchestrate the whole thing, they saw a ripe opportunity with housing and fucked over this country.
Buffett hasn`t bought into Mcdonalds since the 90s moron.
http://beta.fool.com/shmulikarpf/2013/03/21/why-hasnt-buffett-bought-mcdonalds-yet/27513/Yet, Mr. Buffett hasn't bought a single share of McDonald's over the years.
Why Not?
It's a mystery indeed. Yet, I'll try and provide two quick suggestions as to why the Oracle of Omaha left McDonald's untouched.
The company operates in a franchise business model. More than 90% of the company's stores are externally managed by franchisees and not directly by the company. Buffett has never invested in a company with such a massive franchise model. Management, as capable as it may be, will never have full control over all of different stores and franchisees.
McDonald's doesn't really have a strong economic moat, which is a must for any of Buffett's investments. Think about it for a second. Unlike American Express, nothing of McDonald's is proprietary or patent-protected. Unlike Coca Cola, McDonald's doesn't have a secret hidden recipe in a safe. It makes very tasty, cheap burgers, but other rivals know how to make cheap and tasty burgers as well. Put simply, McDonald's has a great brand, but not such a great economic moat.
