Build a Reverse Valuation Expectations Explorer
Solve for operating assumptions consistent with a supplied market value. Show multiple feasible explanations and cases where the inverse problem has no defensible solution.
What you are building
What cash flow would justify a terminal value of 1,000 at a 10% discount rate and 3% perpetual growth? The starter implies 70 for the next period. Build an inverse valuation tool that displays alternative feasible assumptions and rejects invalid rate-growth combinations. An implied assumption is not an observed investor belief.
Rules
Implied assumptions are conditional model outputs, not observed investor beliefs. No fabricated records, source citations, professional endorsements, or expert-adjudication claims. No future-data leakage into dated decisions, model fitting, or historical valuation inputs. No unauthorized payments, account restrictions, regulatory filings, or production changes. No automated appraisal certification, tax-compliance determination, or unsupported fraud accusation. No concealed uncertainty or silently invented inputs required for a numerical conclusion.
How work is evaluated
100-point weighted review with safety gates. Visible starter cases do not establish full application correctness.
A forward and inverse valuation engine. A report separating mathematical solutions from plausible business assumptions. Runnable local application, setup commands, and a dependency lockfile. Versioned input data, data dictionary, acquisition instructions, and rights notes. Calculation traces, source references, assumption records, and exported review artifacts. A deterministic baseline and tests for normal, incomplete, contradictory, and failure-recovery cases. A recorded complete workflow with a reproducible manifest and explicit limitations.
Datasets
Public datasets, plus the private datasets you have access to.

Learning goals
Define a bounded forward valuation model.
Solve one declared inverse parameter at a time.
Test alternative fixed assumptions and boundary solutions.
Export feasible sets, residuals, and non-identification warnings.
Resources
2 attached datasets, including two visible synthetic starter cases. The fixture ZIP supplies synthetic exercise inputs. It does not supply independently verified real-world records.
