You're advising a trading firm after leadership notices a meaningful decline in activity on one of its core trading businesses. The drop could reflect a market-wide shift, normal seasonality, a client behavior change, or an internal issue such as pricing, risk settings, or a workflow problem. The team wants a clear way to separate signal from noise and decide when to treat the issue as a true business problem.
How would you approach a sudden drop in trading volume?
