We reported the bad numbers of PC shipments in Q1 earlier today, and since then Microsoft stocks have dropped by around 4.4% to $28.93 at the time of writing. Not only that, but other technology stocks have dropped, too.
Dell, HP and Intel were down in stock prices riding the news of Q1 shipment numbers. Research firm IDC had partly blamed Windows 8 for the drop in PC sales, noting that HP's shipments declined 24% year-over-year, backed up by Dell's numbers which dropped 11%. Now several Wall Street analysts have downgraded Microsoft stock, so I'm sure we'll see it tumble more in the coming days and weeks.
