I’ve spent 24 years as a civil & structural engineer designing and verifying bridges across Europe, Asia, the USA and Australia — today I lead a bridges engineering team in Brisbane. Bridge engineering is a discipline where the numbers have to be right: every load is calculated from stated inputs, every assumption is written down, and someone independent checks the work before anyone drives over it.
This site applies that same discipline to stocks. For years I ran these models privately for my own portfolio and self-managed super fund — a DCF engine, quality tests, a workbook that interrogates one company for weeks. StocksDeepDive is that engine opened to the public: every input stated, every estimate flagged in red, and the judgment always left with you.
About
StocksDeepDive is built and run by Andres Moreno, a private investor in Australia.
It didn’t start as a website. It started as a personal stock scanner and a very long Excel workbook - tools built to study businesses with a Buffett/Munger-style value lens: compute what the model says a business’s cash flows are worth, test its quality from reported fundamentals, and read what the price has been doing. Over the years the scanner grew a DCF engine, quality calculations, psychology and discovery readings, and a research workbook that documents one company for weeks at a time.
At some point the obvious question arrived: why not open the numbers up? So this site is that - the same engine, the same data work, made public.
Two principles carried over from the private version, unchanged:
The numbers must be honest. Whenever a figure rests on a default or an average because real data wasn’t available, it’s shown in red. An estimate is never dressed up as a fact. I built that rule for myself, because fooling yourself is expensive - it applies just as much now that you’re reading the numbers too.
Value and psychology are different measurements. What the model computes from a business’s cash flows and what the crowd has been doing to its price are reported as separate numbers on every page. Most tools blur them; this site states each one plainly and lets you draw your own conclusions.
The site is free while it launches. When subscriptions open, founding members keep launch pricing. If you want a stock added to the Rational Compounder research list, or anything here doesn’t make sense, use the Feedback button on any results page or email rationalcompounder@stocksdeepdive.com - I read everything.
This site presents factual information and calculator outputs only - it does not provide financial product advice or recommendations; see the disclaimer in the footer. I may own stocks analysed here.
