find the aroc and iroc of a company stock prices

Choose a company and do a web search to find their stock prices over the past several years. (I have found that a search via bing.com often shows a graph of the prices over time right away, but you can find this info via other search engines too.)

Name of the company you chose: _________________________

a. Compute the average rate of change over a 2-year period. Let January 2015 be t=0 and p be the stock price.

First date and stock price ________________ _________________

Second date and stock price _________________ __________________

AROC (rounded to two decimal places):

Interpretation:

b. For the company you chose, estimate the instantaneous rate of change at the beginning of your 2-year period by choosing two points close together, for instance one week apart. Interpret your answer. (Hint: When calculating the IROC, it might be helpful to remember that 1 week is 1/52 of a year.)
