I don't trust brokers and their re-rating, I lost faith in them during dot.com boom and bust, months after the SP of dot.com darlings started their journey south, the majority of brokers were still advising "buy" and only switched to "sell" when the companies joined the 99% club.
I don't mind if the SP reaches 100p in the next six months providing that it revisits the 50's region first.
Your statement about "a nice uptrend that is going to continue for few years" really shows that beauty is in the eye of the beholder. I look at the chart and see that there has been a breakout of the main downtrend red line, but it stalled way below the previous high. This is the fifth attempt at a breakout. All previous four failed (OK, maybe only the first three, the fourth one did stop at a higher low). Maybe it's fifth time lucky. Maybe not. A sudden turn south from here would classify as a false breakout and constitute a classic bull trap.
The truth is that nobody really knows, maybe the SP could indeed carry on north for years to come.
