It's not a good sign, especially the big drop in oil.
Manufacturing activity is drying up, and oil is a huge component.
Tech hype will be hit the hardest.
Twitter will withdraw its November IPO because of market conditions.
I noticed that as well because I follow KBH as a barometer on long term interest rates. If the dollar continues to be debased, and it most certainly will be, there might be a plausible argument to buy houses. Go out long on the lending curve, preferably a 30 year fixed mortgage, and repay the loan with increasingly cheapened dollars. You never pay off the loan early under this scenario. The problem is that lending standards have dramatically tightened, as was proper in light of the subprime fiasco, and a huge component of home sales is all cash offers from investment syndicates and hedge funds, and they rent the homes out for income. This is artificial demand at least in the traditional sense of home ownership.
The temporary prop can and will turn on a dime, at any point rents do not cover the cost of capital.
That could happen when the general population wants to rent beyond their means.
