The last time I wrote about the shares of Marks and Spencer (MKS) was just before the world of Covid-19 kicked in globally. Back then I concluded that “at least the incoming Marks & Spencer CFO knows how to admit a wrong strategy”, and over the last 27 months or so M&S shares have gone down and up. This morning’s rise, after full year numbers publication, of about 11% has taken the shares back to the level of just over 180p of when I last wrote about them. Is the turnaround actually working?
