Percentage change between two numbers A & B can be calculated as: (B-A)/A * 100 For example, if a stock price increases in value from $123 to $145 the percentage increase is: (145-123)/123 * 100 = 17.9% Alternatively, if a stock price decreases in value from $145 to $123 the percentage decrease is: (123-145)/145 * 100 = 15.2% The technically correct answer to the scenario of $145 stock dropping to $123 is a -15.2% change in price. The original answer is semantically correct because the user calls out percentage "decrease", but you cannot have a drop in value and a positive % change outcome.
