LatticeworkTHE EVIDENCE DESK

A free, open walkthrough

A fact is not a thesis. Connect the two.

Start with one assumption, inspect a source, and record what you still need to learn. These examples show the process before you create an account.

Illustrative research, not actual user records, recommendations or a track record. Assumptions and responses below are teaching examples written with the benefit of the displayed evidence—not claims about what someone believed before a filing. Reported values come from the linked SEC filings.

Example 1 · AAPL

Does reported cash flow answer my question?

1. Write an assumption you can question

“The business can generate cash after the spending needed to sustain it.”

2. Inspect what was actually reported

Nine months (year to date) · year-over-year · USD

Company-wide figures, not per-share results. Different share classes can show the same issuer facts.

Both values reported in the current filing. Income is not margin; operating cash flow is not free cash flow. These facts do not explain the cause of a change.

Current: 116,996,000,000 USD · prior: 81,754,000,000 USD.

What this does not establish: Operating cash flow is not free cash flow. It excludes capital expenditure and can be affected by working-capital timing. A year-to-date comparison is not a single-quarter result.

3. Record a response, not a forced conclusion

Illustrative response: investigate further. Read the cash-flow statement and capital-expenditure disclosures over matching periods. Check working-capital movements before judging whether cash generation is durable.

Reconsider if: Repeated weakness in cash generation after necessary investment would make me revisit this assumption.

In My Research, your review preserves the source and thesis versions you considered. Revising your thesis saves a new version instead of rewriting the old one.

Example 2 · MSFT

Does higher profit prove stronger margins?

1. Write an assumption you can question

“Growth can be sustained without persistent deterioration in operating profitability relative to revenue.”

2. Inspect what was actually reported

2024-07-01 → 2025-06-30

Change: +20.78% ($26.71B)

Both values reported in the current filing. Income is not margin; operating cash flow is not free cash flow. These facts do not explain the cause of a change.

Exact values and SEC concept

us-gaap:OperatingIncomeLoss

Current: 155,237,000,000 USD · prior: 128,528,000,000 USD.

What this does not establish: Operating income alone does not establish a margin change. Revenue may grow faster or slower, and the annual result can hide changes within the year. These figures do not explain why results changed.

3. Record a response, not a forced conclusion

Illustrative response: investigate further. Compare operating income with revenue for the same periods, then inspect management’s discussion of costs and business mix. Decide whether the evidence concerns this assumption.

Reconsider if: Persistent deterioration in operating profitability relative to revenue would warrant a closer review, not an automatic trade.
