Understanding equities from the ground up — public study notes
About this series
"I bought some well-known stocks" or "I'm dollar-cost averaging into an index fund because someone said it's good" — these are perfectly fine starting points. But as you continue, questions pile up. This series fills in those gaps, one topic at a time.
- No jargon-first approach — we explain what's happening in plain language, then attach the technical terms
- Read in any order — there's no sequence. Start with whatever interests you
- Written while learning — the author's own study process becomes the content
