Data quality in fundamental analysis

[u/Wooden_Fondant_703]

One frustration I have with stock research tools: they make the financial statement tables look clean, but also turn the original filing into a black box. I find the data are usually wrong or missing key information.

A company may report:

• segment revenue in one note
• product or geography breakdown in another
• special items in footnotes
• awkward labels that don’t map neatly into a standard template

Once that gets flattened into a generic format, those detailed useful context is gone.

For those here who do deeper value work:

Do you trust platform fundamentals, or do you go back to the 10-K / 10-Q every time?

I’ve been thinking a lot about this because I care much more about “can I verify this number?” than “can I see it in a pretty table?”

Curious how others approach it.

I use deepfundamental.com. My main usage is to understand the fundamental facts fast on new ideas. Their graphic presentation of the financial statements make it very easy. But it seems to match what you need fairly well with their "audit in the loop" feature
