Why it's here
From the multi-manager mirror screen
Whale Rock's long book returned +64.7% over the same window where Leopold's mirror did its run — a top finisher among 10 tracked managers, and well ahead of SPY (+25.5%). Concentrated tech growth — internet, software, semis, and AI supply-chain names (Celestica, TTM, Advanced Energy).
About Whale Rock Capital Management

Trado tracks this manager as a mirror strategy + positioning signal. The backtest replicates only the disclosed equity longs (value-weighted, rebalanced each quarter) — options and short exposure are not copied. This is positioning intelligence, not investment advice.
