Ohoh, this might be a real problem for the near term continued up trend.
NYSE 52wk highs
I have never highlighted this chart before, on a quiet day like today, it might be offering a warning to the bulls. It looks like we have negative divergence.
The market itself still looks broadly okay for further up moves, but we are certainly seeing a possible warning. We'll only know in a few more days. A move under SP'1390 would be short term confirmation of some kind of new down cycle.
Good wishes for Thursday
