Berkshire Hathaway drove the price higher
When its IBM deal hit the wire,
So the charge could be made
Of an insider trade,
Since Buffett knew he was the buyer.
In a case of self-fulfilling prophecy, Berkshire Hathaway's purchase of 5.4% of IBM for $10.7 billion prompted a 12% surge in the technology services company's share price once it became public. Although large purchases of public shares must normally be disclosed in 13F filings, the SEC grants about 60 confidentiality waivers every quarter, allowing investors to accumulate shares without driving their prices up. For his part, Mr. Buffett has overcome his fear of tech companies by recognizing in IBM an entrenched service provider with a protective "moat" against would-be competitors. Notwithstanding new highs in the share price, Mr. Buffett believes that, for IBM, the best is yet to come.
Hat tip to... somebody on Twitter for the insider trading joke, and apologies for forgetting who it was.
