The problem is that there's usually a time lag in such instances.
Fact was that in the past (the Moir era), everything was said to be positive and peachy. Now, an analyst in an investment bank will look at the financials but is quite unaware of what us enthusiasts knew. That was a culture of relentless cutting and under-investment that was only going to end in failure. Hence, the share price generally fared ok whilst the dividend was being paid (and at a frankly unsustainable level).
Now you have the opposite. The UK bus business is clearly turning around (in some areas, more prominently than in others). The US Student bus is perhaps stabilising whilst Transit continues to do well. The UK rail has had a cashflow drop (as anticipated) but generally, the news is ok rather than exceptional.
It'll take some really positive news, restoration of a dividend and, dare I say it, time to pass for the sins of the past to be forgotten
and then you'll see the share price increase!!
