Comparable companies, two years later

Another 0.7% stopped without a precise date, possibly only after those two years.
Test of the method
The method was tested on the 497,762 companies of July 2024. Each company was given the bankruptcy share of the same profile a year earlier, in July 2023. The expectation was that 1.6% would go bankrupt within 24 months. In fact 1.7% went bankrupt.
| Group | Expected | Actual |
|---|---|---|
| 1 | 0.2% | 0.2% |
| 2 | 0.3% | 0.5% |
| 3 | 0.5% | 0.6% |
| 4 | 0.7% | 0.8% |
| 5 | 0.9% | 0.9% |
| 6 | 1.3% | 1.5% |
| 7 | 1.6% | 1.8% |
| 8 | 1.8% | 1.8% |
| 9 | 2.9% | 3.1% |
| 10 | 5.6% | 6.1% |
A company that went bankrupt had a higher expected share than one that kept going in 74.5% of comparisons. The level depends on the economy. In a year with more bankruptcies than the year before, the actual share is higher than the expected one.
This is an observation about 6,920 companies, not a prediction for PROTOSSYS. The sector does not count, because the KBO no longer lists a sector for a company that has stopped. By sector, mostly the survivors would count, which would paint too rosy a picture.
