It's the most visible cost of trading, but not the only one: the spread (the difference between the price at which you can buy an asset and the price at which you can sell it at any given moment) is always paid, even though it never appears as a separate cost line, and depending on the broker or market, custody fees or currency-conversion fees can add up too. These costs matter especially when trading frequently -- each trade pays its own cost, which adds up -- or with small amounts, where a flat fee weighs proportionally more."},"relations":{"requirement":[],"contrast":[],"related":[{"concept":{"id":19,"slug":"trade-settlement","term":"Trade settlement","shortDefinition":"The process, after an order executes, in which ownership of the securities and the corresponding money is formally transferred between buyer and seller.","longDefinition":"Executing an order (finding a counterparty and agreeing on the trade) is not the same as settling it.

It isn't deciding a new asset allocation: the target allocation stays the same, and rebalancing is the action of readjusting the portfolio relative to it, not changing it. Without rebalancing, a portfolio can drift over time toward unwanted concentration risk, already covered in Module 3, and lose part of the benefit of the diversification decided in Module 2. It involves buying and selling, which carries a transaction cost and can generate a real tax cost that must be weighed against the benefit of correcting the drift."}}],"calculatedBy":[]},"curricularPosition":[{"id":16,"moduleId":5,"slug":"what-costs-and-fees-does-trading-involve","title":"What costs and fees does buying or selling involve?","summary":"You recognize the costs of trading beyond the broker's visible commission: the spread and, depending on the case, custody or currency-conversion fees.","bodyMarkdown":"## Objectives\n\nBy the end of this lesson you recognize the costs of trading beyond the broker's visible commission: the spread and, depending on the case, custody or currency-conversion fees.\n\n## Content\n\nThe most visible cost of buying or selling is the brokerage commission: what your broker charges to execute the order, either as a flat amount, a percentage of the amount traded, or a combination of both.
