Explanation of risk24 Sep 2019 19:25
I think saying miniscule margins and unpredictability of construction is both correct and an oversimplification. If you are, say, a jeweller then you sell few products at a huge margin. If you are a supermarket, then you're at the other end of the spectrum: lots of products, small margin.
Construction costs are primarily materials and, to a lesser extent, labour. Materials are not subject to much risk - you know the volume of concrete to pour a slab - but also attract little mark-up. Ditto labour. So construction margins overall are low. And unlike, say, share trading, there really isn't opportunity to make a sudden massive profit.
The risks, for a well run construction company are also relatively low. I take the point about unforeseen ground conditions but these can, and are, mitigated to a large degree by good ground investigation.
But over and above everything, construction is a cashflow business. Unlike the supermarkets, who hold their suppliers by the balls, contractors have to pay their suppliers promptly or lose them. Kier have reduced their supplier payment time. This is probably the strongest single signal that they are in recovery mode and on the way back up. Their now defunct competitors went bust because suppliers stopped supplying them.
To declare an interest, my company works as a supplier to Kier and to all the major supermarkets. I'd rather take a contract with the former than the latter.
The problem for the SP is that a large construction company is like a supertanker. It takes a while to change direction. It's not going to start surfing downwind anytime soon. But it's no longer bashing into the waves either. Don't expect sudden transformation in the figures (or the SP) but do expect a steady recovery over the next couple of years.
None of the above will stop the speculators/shifters, who might just succeed in ruining a pretty good company to satisfy their short term greed.
