| Indicator | Score | Reading |

| Crowding Risk lower is better · high confidence | 20/100 | An under-owned, thinly-covered theme relative to AI/compute-style trades; valuations have if anything been marked down. |
| Reflexivity Risk lower is better · high confidence | 47/100 | Mostly earnings-grounded, with leverage risk concentrated in the PE-owned procurement-software corner. |
