Berly Sam Varghese

Founder and Editor, Investor Sam
Dallas–Fort Worth, Texas

Berly Sam Varghese is the founder and editor of Investor Sam: an engineering and technology leader with 18+ years building the systems large enterprises run their operations on, and a private investor in public markets since 2010. Berly designed the AI-assisted pipeline that produces the site's articles and spot-checks a sample of them by hand.

What I am, and what I am not

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 whose career has been about 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.

Background

For 18+ years I have built the systems enterprises bet their operations on — across rail, banking, payments, travel and telecom. Since 2016 that work has been at BNSF Railway, as a consultant through HCL Technologies; today I own the architecture, end to end, of the platform that plans every BNSF shipment — hundreds of thousands of active shipments. I hold a Master of Computer and Information Science from Cleveland State University.

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. 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.

What I cover

  • •Reading primary filings — 10-K, 10-Q and 20-F — and finding the few numbers in them that decide the question.
  • •Forensic accounting screens: Altman Z for distress risk, Piotroski F for fundamental momentum, Beneish M for earnings-manipulation indicators, and the specific situations in which each of them is meaningless.
  • •Sector-specific analysis, because a bank, an insurer, a REIT and a SaaS business cannot be read with the same ratios.
  • •Data integrity itself — when a figure on this site has been wrong, how it was wrong, and what changed so it stops being wrong.

How I work

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.

Most articles here are drafted by an AI-assisted pipeline I designed. I spot-check a sample of them by hand rather than reviewing every one. 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.

When something here is wrong, I would rather hear it than not. Corrections go to [email protected] and the correction policy is on the editorial standards page.
