Question 5 8 pts Which of the following are true regarding the trade-offs that you must deal with when selecting the number of periods of returns to use in a regression to estimate the firm's beta? Select all that apply ☐ The most recent data is likely to be the most relevant because the firm changes over time, so you would prefer not to use observations that are too old ☐ If you use only the most recent data (such as monthly data for the last year), you may not have enough observations to find a good statistical estimate of beta ☐ If you use too many periods, your statistical estimate of beta will be "too good" as you will have removed all of the noise, and you will not be able to use it because of this ☐ If the firm made any major changes that could impact it's risk, you want to make sure that you include both newer and older returns (from before the change) to capture the risk both before and after the change in your estimate of beta
