2016–active retail investor across traditional markets (stocks, REITs, fixed income) and the CS2 skin market since 2023. 479 active positions tracked, 220 historical buys + 79 sells.
Credentials
Active follow-up of stocks, REITs, and fixed income. Methodological background (Sharpe, drawdown, beta, correlation concepts) carried over to skin market analysis later.
Started as a collector of premium pieces (FN, rare patterns). Currently holding 479 active positions — long-term holder profile, not a short-term trader. Full history: 220 buys and 79 sells recorded.
The product was born from a personal spreadsheet maintained since 2023. Motivation: no existing portfolio tracker calculated real net return (marketplace fees + FX slippage + 15% capital gains tax). Instead of solving it just for myself, I turned it into a public product with open methodology.
Editorial philosophy
Numbers before narrative.
Every factual statement on this page is backed by reproducible data: public Steam Market price history, CDI/IPCA benchmarks from the Brazilian Central Bank, monthly active player counts from SteamCharts. The methodology page details the math step by step.
Net return as the default metric.
Traditional portfolio trackers show only gross numbers (pretty, but misleading). Skin Trackers applies marketplace fees + FX slippage + 15% capital gains tax to every reported return. The gap between gross and net over long windows reaches 100 percentage points — hiding it would be dishonest.
No marketplace, no partnership.
The project does not operate skin sales and has no commercial partnership with Steam, CSFloat, or Skinport. That's why I can criticize any of them when the data demands it — something a tracker built inside a marketplace cannot do without conflict.
Nothing here is a recommendation.
The content is analytical and educational. Each reader has a different risk profile, time horizon, and tax situation. CS2 skins are an illiquid, volatile asset dependent on a single producer (Valve) — any position deserves the same due diligence rigor as a small-cap stock.
Conflict-of-interest disclosure
I (Jorgin_) am the solo author of Skin Trackers. I personally hold positions in CS2 skins — 479 active items at the time this page is rendered. The complete buy/sell history is summarized at /historico (live, public for the same Steam ID).
Some skins held may overlap with constituents of one or more STI indices (most likely STI 30 / STI 100). The selection methodology for the indices is purely quantitative (price × listings + history filters) — the indices were defined BEFORE I held any of the current items, and I have not bought or sold a position to influence index composition.
Skin Trackers does NOT operate marketplace activity, does NOT have commercial partnerships with Steam, CSFloat, or Skinport, and does NOT receive affiliate revenue. The newsletter is free; the factsheet is free; the methodology is open. Long-term, the project may offer a paid API tier for professional analysts — that's not the current focus.
Nothing on this site is investment advice. CS2 skins are illiquid digital assets governed by Valve's Terms of Service. Past performance does not guarantee future results. Cross-currency comparisons (USD-denominated index vs BRL/EUR/TRY portfolios) are approximate and depend on FX rate at execution.
