I'm on record as having called the housing crisis, the oil spike, and the dot-com collapse. See
Downside, where I've been making occasional predictions since 2000 based on fundamentals. Take a look at 2006-01-01 on "News" on the Downside site, which I own.
It's not that hard to detect a bubble. The fundamentals will tell you that. For housing, the median house price is normally about 2x to 3x the median income. That ratio hit 4 for the US nationally and went as high as 10 in some markets, like California. It was obvious that something had to give. The housing market was running on "greater fool theory", which never works for long.
But predicting
when a bubble will collapse is tough. Both I and Burry expected it a year or two earlier than it happened. It was blindingly obvious that something had to break. But when? The Fed kept interest rates artificially low for several years longer than they should have, which both postponed the inevitable and made it worse when it happened. As William McChesney Martin, Chairman of the Fed in the 1960s, wrote, it is the duty of the Fed "to take away the punch bowl just as the party gets going". Greenspan failed in that duty.
Burry had to maintain his short positions for longer than was comfortable, and he bailed out just before things really tanked.
From a more general perspective, part of the problem was the refusal to recognize the runup in housing prices as inflation. We used to hear talk of a "wealth effect" from increasing housing prices. But that was fictitious, and we don't hear that phrase used much now. House prices are vastly underweighted in the CPI (a change in the 1980s), and this distorts our view of inflation.
