If you’re wondering what could cause the stock market’s slide to steepen, look no further than today’s forecast for T-Bond futures. It would appear that the 129^03 bear-market target we’ve been using for months is unlikely to turn the tide.  My new target equates to 30-Year yields of perhaps 4.12%-4.15% — quite enough to shut the pie holes of those who have been saying the spike in rates so far is no threat to the nascent boom in home  prices.
