There’s a chart signal that’s generally more reliable than a weather forecast and currently Marks & Spencer Group (LSE:MKS) are displaying it quite explicitly.

In fact, we could even say that “this isn’t just a chart signal, it’s an M&S chart signal” with a reasonable hope that our projected outcome will prove to be correct.
Of course, there’s always a fly and always some ointment, but visually this one looks pretty amazing.
The chart extract below shows a green line representing the price level above which we require the share to close, potentially presenting a scenario where some real price growth can be anticipated.

Essentially, in a textbook example of our thoughts, share price closure above 360p should make movement to an initial 375p almost certain. Our secondary, if exceeded, calculates at a future 393p. This sort of near-10% price recovery would emplace the share price on a path to a long-term 428p.
But of course, this is the stock market and it’s rare for something as obvious as this to appear. Thus, we should suspect that a trap for traders is looming, aside from the absurd (but real) detail of “that’s what they’d want us to think!”
To be blunt, we do anticipate M&S enjoying an upwards surge and given share price movements since July, it looks pretty confident.
The share price needs to close below 330p before the need to buy “these are not just any running shoes, these are M&S running shoes...”
