Explanation


Statement 1: As the statement says about the most expensive stocks, sort the table by price. It is clear that Ceta and Gati are two of the most expensive stocks now that their price has changed horizontally. Both have the least change in price, hence the statement is correct.

Answer: True

Statement 2: Sort the table by price of the stock; the two least expensive stocks are Dega and Icha. Compare horizontally. Dega has two negative price improvements; hence, it must not be the stock with maximum growth over this period. The statement is incorrect.

Answer: False

Statement 3: Similar to statement 2, the cheapest stock in the beginning of the period is Icha which went highest during this period. The statement is correct.

Answer: False

­Icha's price on 30th June = 6.99

Now work the percent change in the backward.

6.99/122.7*100 = 5.70

5.70/119.1*100 = 4.79

4.79/152.8*100 = 3.13

3.13/141.7*100 = 2.21

2.21/121.2*100 = 1.82

1.82/131.7*100 = 1.38

So the price at the beginning of 6 month period was $1.38, and is the cheapest.

­The two least volatile stocks are also the two most expensive ones. => True
Sort by Price on 30th Jun 2016 ($) => the 2 most expensive ones are Ceta an Gati
  • As per the table, most of the % change of these stocks are quite small, less than 5%
  • Sort by % change of each month, the % change of these stocks are always among those most near 0
=> least volatile

The cheapest stock at the end of the six months period is the one to undergo maximum growth over this period. => False

Sort by Price on 30th Jun 2016 ($) => cheapest stock is Dega
Icha underwent a higher growth (all 6 months experienced higher increase than Dega)

The cheapest stock at the beginning of the six months period is the one to undergo maximum growth over this period. => True

The cheapest stock at the beginning of the six months period => Icha because
  • the price at the end of 6 month period is one of the smallest
  • underwent highest growth (all 6 months experienced very large percent increase)

Q.1. The two least volatile stocks are also the two most expensive ones.
Sort the table by price given in the last column. The most expensive are ceta and Gati. If we quickly scan the 6 months changes, we can realise that the two remain in the range -5.4 to 4.1, while others change over a much wider ratio. YES

Both 2 and 3 are based on the the stock with maximum growth. When you scan by price, the second cheapest has the maximum growth, so

Q.2. The cheapest stock at the end of the six months period is the one to undergo maximum growth over this period.
NO

Q.3. The cheapest stock at the beginning of the six months period is the one to undergo maximum growth over this period.
The second cheapest has a growth of 31.7%, 21.2%, 41.7%, 52.8%, 19.1%, 22.3, while the price was just 6.99
Surely the price initially would be less than at least half. The cheapest at 5.57, on the other hand has very limited growth. So surely second cheapest was the cheapest at the beginning. YES
