By the end of this lesson you know the real criteria for choosing a broker -- regulation, fund protection, available markets, execution quality -- beyond who charges the lowest commission.
\nChoosing a broker based only on who charges the lowest commission is a risky oversimplification. You already saw in the previous module that the explicit commission is only part of the real cost of trading -- and it's far from the only relevant criterion for deciding who to trade with.
\nA first criterion is regulation: is the broker authorized by a recognized financial regulator? Trading with an unsupervised intermediary, even if it offers attractive terms, forgoes the protections regulation requires -- like the account segregation already covered in the previous lesson.
\nA second criterion, directly tied to the first, is fund protection: if the broker goes bankrupt, is there an investor compensation fund that covers your money or securities, and up to what limit? This fund doesn't protect against your investments' price falling -- that's market risk, something different -- but specifically against the broker's own insolvency.
\nOther practical criteria matter too: which markets and assets are available through that broker, the quality and real cost of order execution (including the spread already covered in the previous module), and the tools and customer support it offers. None of these criteria replaces the visible commission -- they're all considered together.
\nTwo brokers might offer a very similar brokerage commission, but only one is a member of a recognized investor compensation fund in its country. That difference matters more, should the broker run into trouble, than a few cents of difference in the commission on each trade.
\nChoosing a broker requires looking beyond the visible commission: regulation, fund protection, available markets, and execution quality are equally or more relevant criteria.
\nWhy can choosing a broker based only on the lowest commission be a bad decision?
\nWhat exactly does an investor compensation fund cover, and what does it NOT cover?
