Those are companies people don't get attached to. Apple and other tech companies are a much more personal choice, generally. It probably also helps because those people are excited that Apple is making more money, allowing them to deliver more new and innovative products then would be possible with lower cash flow.
I guess I must be old school, I'm a consumer and I think about my wallet before the corporations treasure chest. Apple isn't pumping most of the profits back int the company or paying it out to shareholders. It's sitting in the bank. Or maybe they have something unimaginably huge in mind and I guess that is a possibility.
