If I were to steelman the other side.....one might argue that the stock market investors....are looking through current bond prices....to a future period when they return to much lower levels.....such that they are front running an expanding ERP by owning stocks now knowing that there is a bond rally to come. I'm not so convinced........i think the US has worked for so long....that its going through what has all the appearances of being a melt up.....as investor pull funds from across the globe in under-performing markets to pile into the asset class with the best 3,5,10yr record....SPY/QQQ....
