To calculate the total change in value for the week, we need to add up all the increases and decreases.
Increase = 1423 + 1423 = 2846 points
Decrease = 10 + 813 + 1223 = 2046 points
Total change = Increase - Decrease
Total change = 2846 - 2046
Total change = 800
Therefore, the value of the stock changed by 800 points that week.
The correct answer is 800 points.
