Transaction Cost Normalization

Cost

Transaction Cost Normalization (TCN) represents a suite of techniques designed to mitigate the impact of trading frictions on portfolio construction and performance evaluation, particularly relevant in markets characterized by high volatility and fragmented liquidity. It aims to level the playing field by adjusting returns to account for the costs incurred during trading, providing a more accurate reflection of underlying asset performance rather than the effects of execution strategies. This is especially crucial when evaluating strategies that involve frequent trading or operate in markets with significant bid-ask spreads, such as cryptocurrency exchanges or options markets. Effective TCN allows for a clearer assessment of alpha generation, separating skill from the inherent costs of market participation.
