I'm Bing Bing, the person who runs Bong Stocks

I planned this site, built it, and keep it running every day. Bong Stocks is not a company; it is a site run by one person. The planning, the data collection, the calculation rules, the layout and the bug fixes are all mine.

I am not an analyst and not an investment professional. I don't think I'm qualified to tell anyone which stock to buy, and this site never does. What I do is take scattered public data and put it into a form a person can actually read.

Why I built it

When I started investing, the frustrating part was how hard it is to understand a single company. Portals give you numbers, but they never tell you what the numbers mean. Is a P/E of 12 cheap or expensive? What does this company actually sell to make money? Does yesterday's filing matter or not? The things I actually wanted to know were not organised anywhere.

Brokerage research is written in professional language. Videos and forums lead with conclusions rather than evidence. A beginner ends up either trusting someone else's conclusion or buying blind. I thought there should be something in between: you make your own judgement, but the material you need to judge should be there, in plain language.

The obstacle was scale — over 2,600 listed companies in Korea. One person cannot read them all. So I used AI and automation. Machines read the filings, compute the metrics and draft the text; I decide what standards to apply and whether the output is right. That division of labour is documented openly in AI & Automation.

What I actually do

• I set the standards — P/B for banks, NAV for holding companies, forward P/E for semiconductors whose earnings swing. Deciding which metric leads for which sector cannot be automated, so I classified and organised it by hand.
• I look for what's wrong — I open pages and check the figures and labels myself. When something looks off, I trace the cause.
• I stop the same mistake recurring — when I find an error I don't just patch the page. If the rule caused it, I change the rule, re-run every company, and add an automated check that catches it in future.

For example, large-cap automakers trading below book value were once labelled “overvalued” — an artefact of comparing against the sector median. Instead of editing those pages, I added an exception to the rule, recomputed everything, and built that case into the checks that run on every update. Those records are published in Corrections.

Principles I hold to

• No recommendations — no buy/sell opinions, no price targets, no stock scores or rankings. This isn't a preference; it's enforced in code. Text containing such language fails the automated check and is not published.
• Public data only — FSC market data and DART filings, sources anyone can see. No brokerage research or paid data is republished.
• No hidden formulas — every calculation and assumption is written out in Methodology.
• If I don't know, I say so — where there isn't enough basis to estimate, the value is marked unavailable rather than invented.

Conflicts of interest and editorial independence

When money is involved, readers deserve to know up front who could influence what is written here.

• Holdings do not shape the write-up — I do invest in Korean equities. But every figure on this site is computed by formula, and the written analysis follows a fixed protocol with automated checks. There is structurally no point at which a particular stock can be talked up or down. The site produces no buy/sell opinions and no price targets, so it is not the kind of writing a holding could profit from.
• No paid coverage — I do not accept money or equivalent consideration from companies, asset managers, brokerages or PR agencies to cover a stock or ETF, to change what is written, or to alter where something appears. There is no sponsored or affiliate content; if that ever changes, it will be disclosed on the page itself.
• Advertising does not touch the content — Google AdSense ads run to cover hosting and data costs. They are served automatically, and no advertiser influences any stock's figures or narrative. Ads are visually separated from the content.
• No stock gets removed — I do not delete unfavourable facts or take down pages at a company's request. If a fact is wrong it gets corrected, and the correction is logged in Corrections.
