This is a weekly measure
(Although through much of 2017 'weakly' would have been a more appropriate spelling)
A good sized jump on the week to 116.5
- from last week's 115.1
4 week MA is around 115.6, longer run average is around 112.9 .... so back above both this week. It does tend to jump back and forth around the 4 week MA though (maths, innit?)
