you can do that but many institutional investor can not do so. I personally think the money from debt market will flow to other market( stock, commodity, other bond market). people pull money from the most safe bond market(tbond),does not mean they will put into stock market. they can put into corporate bond to get a better yield. The key of lowering treasury yield is that the confidence in market is recovering. That would sustain a good stock/bond market. So I am very bullish on the stock market in midterm
