What is transaction cost analysis?

Transaction Cost Analysis (TCA) is a process used by financial professionals to evaluate the costs associated with trading securities, such as stocks or bonds. It helps firms understand the explicit and implicit costs incurred during trading, including commissions, fees, market impact, and slippage. By analyzing these costs, firms aim to improve trading strategies, enhance execution quality, and reduce unnecessary expenses. TCA is essential for ensuring best execution and regulatory compliance in financial markets.
