How this is measured: The daily balances come from eToro; the calculation is ours: time-weighted, deposits and withdrawals removed. The line shows what the money did, not how much was added. Net of all costs that arise in the account. The account is publicly viewable at eToro. It has run since May 2025, and so does the series.

What Thermik does

It buys what is rising and staying calm while it does: shares in an intact uptrend, measured across several horizons.

How much a position weighs is decided by its own volatility. Calm names carry more, restless ones less.

Once a month the book is rebuilt. What loses the trend leaves; what has it may move up.

No forecasts, no news, no opinion. Rules applied the same way every month.
