With all of America's 401k's flowing into equities and with CNBC continually saying bonds are the worst trade around, one has to determine if continuing to buy here is the smartest way to go or take partials, roll up your stops and raise cash rather than buying this top.
Technically the monthly chart shows MACD posed to bear cross although the month is far from over. The bollinger band is flattening out which does not say to "buy" here but remain cautious and sit on hands.
Here TLT for a quick glance at the monthly and yeah, it's still selling. Could see a temporary bounce (here or there) but overall, the trend is still down so equities (or cash) it is.
I believe traders are taking profits at this fibonacci extension ahead of the June FOMC meeting and why not. The 10 year Treasury has been on a move and if the Fed doesn't raise (which most don't think it will) it can return to oversold and ramp up again before September.
