Sajjad1994 How is Icha the cheapest at the beginning of 6 month period?
­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

We need not calculate the price at the beginning of six months for all stocks, right? It is apparent from the data of Icha that it is the correct answer for 3rd part.

It's immediately apparent that it's the cheapest and undergoes the most significant growth, so no need to calculate.

Is it possible to solve it under 2min? it took time to calculate so much
Sajjad1994
The table summarizes the movement of the prices of ten stocks in a portfolio. The percentage change suggests the fluctuation in the price of stock as a function of the price at the end of the previous month. Negative sign suggests that the price decreased. The last column suggests the absolute price of the stock in US dollars on 30th Jun 2016.

You don't have to calculate much, you can sort the table so that you only get the information necessary and working backwards from the questions makes it easier. For example, rather than calculating the volatility of each stock, take the two most expensive stocks and check their volatility then try and find one that's clearly more stable.
