Abstract
Using different descriptions of the Cuntz semigroup and of the Pedersen ideal, it is shown that $\sigma $-unital simple $C^*$-algebras with almost unperforated Cuntz semigroup, a unique lower semicontinuous $2$-quasitrace and whose stabilization has almost stable rank $1$ are either stable or algebraically simple.
