Educational only. Not investment advice. All companies and numbers in the examples are fictional.

Issue 2 · October 2026

Check the numbers behind the headlines before you trust them

10 short lessons on what a number is really answering: why an “insider sold” alert can be shares withheld for tax, how to tell a fresh private fundraise from a yearly update, how to compare company quarters fairly, whether “record profit” turned into cash, how to read yield-curve charts, and how to spot a cherry-picked track record.

Issue 1 · September 2026

Tell a viral trading alert from what the document actually says

12 short lessons on checking a social-media alert against the source: a five-step way to find the right filing, why “just filed” is not “just happened”, what insider buys and sells really show, why a big fund’s quarterly holdings list is a snapshot rather than a buy signal, what crossing 5% ownership means, and why a buyback announcement may not shrink the share count.
