Systematic Portfolio Research for Independent Investors
TradingAlgo Mosaic helps investors review global equity markets through weekly model portfolios, transparent selection rules and risk-aware validation.
TradingAlgo Mosaic is designed for independent investors and financial professionals managing meaningful capital, who want a disciplined framework for reviewing equity markets without relying on market noise or discretionary opinions.
Independent investors
For people who manage their own portfolio and want a structured weekly reference before making allocation decisions.
Risk-aware capital
Most useful when portfolio size makes diversification, transaction costs and research cost proportionate to the capital managed.
Active portfolio review
For investors willing to review model portfolios, benchmark context, drawdowns and weekly changes before acting.
Not a signal service
Not designed for investors looking for short-term trading calls, guaranteed returns or personalized financial advice.
Risk comes first
Research is useful only when the risk is visible.
TradingAlgo Mosaic presents model portfolios as standardized research outputs. The service is built to make assumptions, history and limits easier to inspect before an investor decides whether a portfolio is suitable for their own circumstances.
Benchmark context
Each market report compares model behavior with a reference benchmark.
Drawdowns shown
Historical declines are part of the analysis, not hidden behind performance summaries.
No performance promise
Past results, simulations and backtests are evidence to review, not forecasts or guarantees.
Investor responsibility
Position sizing, suitability and final investment decisions remain with the investor.

Every investment process begins with strategic asset allocation.
Once an investor has decided how to allocate capital across major asset classes, such as equities and bonds, and geographical regions, for example United States, Europe or Japan, the next decision is how to gain exposure to each market.
The most common solution is to invest in a broad market ETF, which provides transparent exposure to a well-defined benchmark.
TradingAlgo Mosaic offers an alternative.
Instead of holding every stock in the benchmark, it applies a transparent quantitative framework to identify a concentrated portfolio of stocks that best represents the market at that point in time. The portfolio is reviewed weekly using predefined selection rules based on trend, stability and portfolio construction principles.
The objective is straightforward: to provide a systematic alternative to passive index investing, seeking to outperform the reference ETF while maintaining a transparent, disciplined and repeatable investment process.
Investment decisions always remain with the investor. TradingAlgo Mosaic provides standardized research and model portfolios, not personalized investment advice.
Illustrative example based on US equities and SPY. The same framework can be applied to other supported markets and reference ETFs.

Portfolio Construction
Your signals are transformed into a portfolio framework: universe selection, position sizing, diversification rules, rebalancing frequency and risk limits.
Validation and Stress Testing
The strategy is tested on historical data to understand behavior, drawdowns, turnover, benchmark comparison and the conditions where it works or struggles.
