Portfolio methodology
How SignalTrack computes public portfolio numbers and writes their summaries.
Data
Every position comes from transactions: buys, sales and transfers with price, amount and date. Prices of listed coins update every few minutes; the portfolio value is stored hourly.
Weights and concentration
A weight is the position value divided by the portfolio value. Concentration is the combined weight of the three largest positions. Stablecoins, meme coins and market-cap groups (top 10, top 100, the rest) come from coin tags and market rank.
Return vs Bitcoin
The 30 and 90 day return uses the modified Dietz method: new money added during the period is not counted as profit. Bitcoin is measured over the same dates.
Risk profile
A rule, not an opinion: speculative when meme coins reach 20% or coins outside the top 100 reach 50%; conservative when BTC, ETH and stablecoins reach 70%; aggressive when altcoins reach 60%; balanced otherwise.
Targets and track record
Price targets are the author's exit levels. Track record counts the author's published signals that SignalTrack verified against market prices.
Texts
Summaries are written from the computed facts only. Every number and date is inserted when the page is served, so it matches the current data. A validator rejects text with numbers or coins outside the facts, relative dates, advice or forecasts.
Indexing
A public portfolio is indexed by search engines when it has at least 3 positions.
