Given that firms adapt their plans as events unfold, the early readings on investment intentions for a given year often turn out to be wrong. We can see the extent of this by comparing the early estimates for a given year with the final (seventh) estimates in the Capex data.
This is shown here based on the third estimate, which is what we currently have to hand for this financial year (Graph 8). We can see that even over the course of just a few quarters, business investment can turn out to be quite a bit higher, or quite a bit lower, than the most recent reading from the survey suggests.
