Determination of where, when, how, and how much 
capital to spend and/or 
debt to acquire in the pursuit of making a 
profit. An investment decision is often reached between an 
investor and his/her 
investment advisors. Depending on the type of 
brokerage account an investor has, 
investment managers may or may not have tremendous leeway in making decisions without consulting the investor himself/herself. Factors contributing to an investment decision include, but are not limited to: capital on hand, projects or opportunities available, general market conditions, and a specific 
investment strategy.
