An exceptional run on Apple stock over the past few days has made Apple's stock value worth more than either of its two most direct rivals combined. A comparison has shown that, as of mid-day Thursday, Apple's market cap of about $456 billion was greater than both those of Google ($198.9 billion) and Microsoft ($256.7 billion). As noted by AppleInsider, Apple was taking advantage of both Google missing targets and bruising its share as well as Microsoft's historic inability to excite shareholders.
