WB might well have gotten those three blue chips WITHOUT trading them, by way of Inheritance from his prosperous US Congressman/stock broker father who died at age 60 on April 29, 1964, around the time Berkshire Hathaway was launched as a holding company. Entirely reasonable for BRK to emulate some of Pop's favorite holdings, especially widely held blue chips like JNJ and perennial WB/Munger favorite, Wells Fargo.
I don't understand about the Walmart shares. WMT didn't go public until 1970. Warren's inheritance has never been publicly spelled out.
Several online sources say WB became a millionaire around 1962 and was involved with a lot of stock via several investment partnerships.
