Sornette and Johansen show log-periodic oscillations on an accelerating pre-crash price rise as a critical-point precursor, though not under the names super-exponential or discrete scale invariance.
“the overall accelerated increase before the crash as much a s two years before it and its decoration by large scale oscillations whose linear frequency increases”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
