# Applied cases: see the research method in use

> Practice source-based project analysis with a dated public-filing case. Separate reported facts, calculations, interpretation and open questions.

Applied cases show the method on identifiable source material. Each case states its period, evidence and limits, so readers can distinguish historical observations from calculations and interpretation.

## Start here

[An annotated project analysis: NVIDIA's FY2026 filing](/academy/applied-cases/nvidia-filing-analysis/)

The case uses a dated issuer filing to examine revenue, gross margin and direct-customer concentration. It reproduces the arithmetic, explains the limited conclusions and leaves further questions open rather than manufacturing a target price or project score.

## What you will practice

Preserve the source period and units. Identify who prepared the document. Reproduce a calculation. Explain what the numbers do not establish. Turn unanswered questions into a focused research plan.

This Academy case is not an evaluation submitted by one of Orbitrum's named experts and is not added to the project's scoring history.

## Choose your perspective

**For experts:** use the format to make the difference between reported information and your interpretation easy to inspect.

**For readers:** check whether a conclusion goes beyond the material shown and whether its date matches the question you are asking today.
