To solve this problem, we need to calculate the percent increase or decrease for each stock. The formula is:
Percent Change = [(Current Price - Purchase Price) / Purchase Price] × 100
We’ll go one by one.
---
a. Visto Networks, Inc.
Purchase Price = 20.75
Current Price = 43.625
Change = 43.625 - 20.75 = 22.875
Percent Change = (22.875 / 20.75) × 100 ≈
110.24% → Increase
---
b. Time Warner
Purchase Price = 7.5
Current Price = 9.175
Change = 9.175 - 7.5 = 1.675
Percent Change = (1.675 / 7.5) × 100 ≈
22.33% → Increase
---
c. Microsoft
Price = 22 (this is purchase price)
Current Price = 25.22
Change = 25.22 - 22 = 3.22
Percent Change = (3.22 / 22) × 100 ≈
14.64% → Increase
---
d. Amazon.com
Purchase Price = 11.5
Current Price = 9.85
Change = 9.85 - 11.5 = -1.65
Percent Change = (-1.65 / 11.5) × 100 ≈
-14.35% → Decrease
---
e. Dell Computers
Purchase Price = 71.5
Current Price = 68.45
Change = 68.45 - 71.5 = -3.05
Percent Change = (-3.05 / 71.5) × 100 ≈
-4.27% → Decrease
---
f. Ford
Purchase Price = 31.5
Current Price = 18.375
Change = 18.375 - 31.5 = -13.125
Percent Change = (-13.125 / 31.5) × 100 ≈
-41.67% → Decrease
---
g. Sears
Purchase Price = 61.5
Current Price = 68.375
Change = 68.375 - 61.5 = 6.875
Percent Change = (6.875 / 61.5) × 100 ≈
11.18% → Increase
---
Now, let’s count how many stocks went up vs down:
- Up: Visto, Time Warner, Microsoft, Sears →
4 stocks
- Down: Amazon, Dell, Ford →
3 stocks
So more stocks increased than decreased.
Also, looking at the big picture — even though some dropped a lot (like Ford), others rose significantly (especially Visto). So overall, yes — it was a good day for stocks based on this sample.
Final Answer:
a. +110.24%
b. +22.33%
c. +14.64%
d. -14.35%
e. -4.27%
f. -41.67%
g. +11.18%
Yes, it was a good day for stocks because more stocks increased in value than decreased.
