# Portfolio Alchemy – How Small Changes Create Big Differences

Building a trading portfolio is a kind of alchemy.

It’s not just about finding profitable strategies — it’s about how you **combine them**.

Even when every strategy works well individually, their **correlations, volatility regimes, and weighting** determine whether your portfolio reaches new equity highs or struggles with drawdowns.

In my live trading, I discovered how **small structural changes** — like adding two strategies or slightly reducing index exposure — can transform overall performance.

The blue line shows the optimized version of my portfolio, while the orange one represents my live results.

Both use robust strategies tested over 15 years — the only difference lies in portfolio construction.

That’s what makes trading an art.

A mix of logic, statistics, and intuition.

A kind of modern-day **alchemy**.
