Do people believe that markets can turn very quickly? I was just thinking that there was plenty of queuing for high rises in Sydney back in '03 / '04, and the market suddenly turned. Business hasn't suddenly died in Sydney: unemployment is still low, bars, restaurants, etc are still doing good business. The interest rate rises, petrol and food price increases just started to bite.
If anything, I would imagine a 'sudden' increase in salary would drive people to buy properties that they can't really service (but they can't tell because they don't have the experience). How many people in Perth are mortgaged to the hilt even with their suddenly high salaries? It's always a gamble if your exit strategy when things go bad involves selling to a bigger idiot: when circumstances deteriorate for you, it probably will for others.
Shares for mining companies, for example, are off their highs. Why? Surely their fundamentals are great too. Just because the fundamentals are good doesn't mean prices can't overshoot (and vice versa). The biggest crashes occur when people both overestimate the fundamentals AND prices overshoot even those optimistic expectations. There's no shortage of ore in the world, but there is a current shortage of mines to extract them. How long before new mines come on line?
I still think the issue is growth expectations. Investors in Perth are looking for 20%, 30% growth that can't be sustained. If growth expecations 'cool' back to 8%, those investors are going to sell and go for something else, driving the price and growth down. Assuming the market is driven by people (both PPOR buyers and investors as that's the only way you can justify buying at 3% yields) who expect 30%, what are they going to do when growth winds back to 8%? It's like companies whose shares get pummelled when they miss earnings by a penny. Fundamentals may be perfectly fine but current prices are based on expectations of the future. If the expectation suddenly shifts.....
