Interesting! I had thought about it too. If you correlate QCOM stock price and housing between 2000 and 2006 you’ll get some answer. I don’t think that high tech jobs were the sole reason, but sure think it was a contributor. I know some people who sold a bunch of QCOM options to put down around 30% for ~600k homes. I think these people bid up the prices and others started relying on exotic mortgages to compete with them, which sort of fed the frency.
