You are analysing U.S stock markets. You have been provided weekly adjusted close prices
for NASDAQ (National Association of Securities Dealers Automated Quotations) Composite
index, Intel Corporation (INTC), and Microsoft Corporation (MSFT) for the period of
January 2010 – December 2019.
Data available via Resources – Assessment resources — Assignment folder.
Please complete the following questions:
1. Calculate weekly holding period returns for the NASDAQ index, Intel Corporation
(INTC) and Microsoft Corporation (MSFT) stocks prices, respectively.
2. Which one has the highest relative risk among the weekly returns of NASDAQ index,
INTC and MSFT? Provide evidences.
3. Assuming Normality, what is the probability of the INTC returns above 3%? What is
the probability of the MSFT returns being between -2% and 2%?

Model A: Assuming a linear relationship between INTC returns and MSFT returns.
Model B: Assuming a linear relationship between INTC returns and MSFT returns
and NASDAQ index return jointly.
6.1: For model A, is the intercept coefficient significant at 5% level? is the slope
coefficient significant at 1% level?

and interpret it.
