Johnson tells Martin that communication speed is SAMN’s current highest priority. All of SAMN’s competitors have increased their communication speeds in recent months, and Johnson says management wants SAMN to be faster than its competitors. SAMN’s trading desk is located in a residential area far from downtown where the exchanges it works with are located. SAMN’s trading team is relatively large with experienced investment professionals, and the firm recently invested in fast computers with the latest algorithms.

Which of the following changes should SAMN make to address its key priority?

选项：

A.

Hire more investment professionals

B.

Upgrade to more complex operating systems

C.

Move the trading desk physically closer to the exchanges it works with

解释：

C is correct. The speed required by electronic traders is affected by fast communication and fast computations. The shorter the distance between the trader and the exchange, the faster the communication. Many exchanges allow electronic traders to place their servers in the rooms where the exchange servers operate, a practice called collocation.
