What is your prediction, market going down?
It can continue to diverge in the short-run, and in fact can diverge again and again in other short runs, without warning and at any point. That's my foremost prediction. And a chart like this will never pin-point a top or bottom.
But can I predict that the chart will continue to experience short-term divergences yet continue following the long-term path as it's done thus far? If I didn't, well that might be something akin like fighting a long-term trend, indeed.
I think the chart says that market has been pricing in the next 2 year's worth of crummy bank returns relative to it's lending activity in the market for the past two years. You can lead a horse to liquidity...
