The FTSE100 is clearly in a bear market
It's running under the Ichimoku cloud, the 50 day MA is turning lower, RSI moment is bearish and major UK stocks are heading back to their March lows. There seems to be a small section of UK stocks that are doing well, but even those are looking a little overstretched now.
Levels to look out for 5,700 and major support at 5,550.
I have linked to my last idea where I went over in detail the bull and bear cases for the FTSE should you want to learn more.
