I am not a financial advisor, a broker, a fund manager, or a research analyst at any institution. I hold no securities licence and no finance qualification, and I am not registered with any regulator. Nothing on this site is personalised advice, and I am not permitted to give it — nor do I want to.
What I am is an engineer who has spent his career making large, messy datasets trustworthy, and a private investor who got tired of paying for research that would not show its work. Investor Sam is the tool I built for my own decisions, made public. That is the entire claim, and I would rather state it plainly than dress it up.
For nineteen years I have led the engineering behind systems enterprises bet their operations on — across rail, banking, payments and travel. Most recently I served as the architecture authority for the trip-planning platforms of North America's largest freight railroad: the system that re-plans hundreds of thousands of shipments, millions of times a day. I hold a Master of Computer and Information Science.
That background is the relevant one here. The hard part of this site is not opinion — it is ingesting SEC EDGAR filings for 8,200+ companies, reconciling inconsistent XBRL tags, catching the filer whose share count is off by a factor of a thousand, and refusing to display a number we cannot trace. That is a data-engineering problem before it is a finance problem.
I have invested in public markets on my own account since 2010. Earlier in my career I paid off roughly $450,000 of professional-school debt, which is where the no-shortcuts, show-me-the-arithmetic habit comes from. I own positions in some of the companies this site covers; where that is relevant to something I have written, it is disclosed on the piece.
Every article is written to teach a method that transfers to any company, worked through with figures you can look up on this site and verify against the filing. I do not publish price targets, model portfolios or trade calls.
I review and approve every guide before it goes live, and I review the generated summaries on company pages. Where a page's narrative was drafted from filing data by a language model, it says so on the page. The scores, ratios and statements themselves are computed arithmetically and are never written by a model.
