This free snapshot doesn't read filing or proxy text, so the auditor-quality and governance checks that can lower a grade were not evaluated (auditor quality, say on pay, board independence, going concern). Those checks only ever lower a grade, so the full analysis can land below the grade above but never above it — treat it as the most favourable reading, not the settled one.

Monolithic Power Systems, Inc. earns a C (Mixed — selective) forensic quality grade, and its balance-sheet distress test reads 11.6, placing it in the Safe zone. 1 forensic signal was flagged in its latest SEC filings, led by cash conversion.
