A fairer comparison
Compare every company through the same lens.
A metric only becomes useful when the definition stays consistent. Openbook puts each company through the same scoring framework, so differences are easier to interpret.
- Put Growth, Momentum, Profitability and Valuation scores side by side.
- See the financial inputs behind the scores, not just the final number.
- Separate potential reward from the risks that could undermine it.

Valuation in context
A cheaper stock is not always better value.
Compare valuation alongside growth, quality and expectations. A lower multiple may reflect an opportunity, or it may reflect a weaker outlook.
- Review multiple valuation measures instead of relying on one ratio.
- Set the price against expected earnings growth and profitability.
- Use the gap as a research prompt, not an automatic conclusion.

The useful question: is AstraZeneca's higher multiple justified by its growth and profitability profile, or are expectations already demanding?
Performance over time
Compare direction, not just a single snapshot.
Two companies can report similar margins today while moving in opposite directions. Trend comparisons reveal whether financial quality is strengthening, stalling or deteriorating.
- Follow revenue, earnings and margin trends across reporting periods.
- Spot widening gaps and potential inflection points earlier.
- Move from the comparison into each company's full research page.
