IBM shareholders have had a brutal few weeks, and if you have been following our coverage you saw most of it coming in stages. On 14 July the stock fell just over 25 percent in a single session, the worst day in at least 58 years of trading records and quite possibly the worst since the company’s predecessor listed in 1916, after CEO Arvind Krishna pre-announced second quarter numbers below consensus. Shares that closed at $290.23 the day before, near its recent high, now hover just above $200, with roughly $67 billion of market value gone in a day.
