Analyst Note
| Greggory Warren, CFA |With wide-moat-rated Berkshire Hathaway already giving us a decent glimpse of its buying activity during the first quarter, there were only a few things in its recent 13-F filing that we would consider new information. When Berkshire reported earnings earlier this month, it noted it had purchased $51.1 billion and sold $9.7 billion of equity securities during the March quarter.
