The question refers to a spreadsheet containing monthly returns for Stock A and the market over five years, and asks for the beta of Stock A. In beta calculation, beta = Covariance(stock, market) / Variance(market). Since the actual numerical data from the attached spreadsheet isn’t accessible here, we can’t recompute the statistic directly. The provided answer choices include a single numeric option as the presumably correct beta and a couple of distractors, plus a “None of the other options” choice.

Option 1: '1.27' — This value sits in a plausible range for a stock with somewhat higher systematic risk than the market (beta > 1). If the spreadsheet’s computed beta equals 1.27, this option would be the correct numerical result. The reasoning would hinge on the sample covariance between Stock A and the market being about 1.27 times the market variance.

Option 2: '1.41' — This is another beta value that is plausible for a stock with above-average sensitivity to market movements. If one were to eyeball or miscalculate using a subset of data, or miscompute the regression slope, this could appear—but it would indicate a slightly stronger tie to market movements than 1.27.

Option 3: '0.07' — A beta this low implies Stock A moves almost independently of, or very little with, the market, or it could reflect a calculation error such as dividing by a much larger variance than appropriate or mixing up units. In practice, a beta near zero is unusual for a stock that has any meaningful exposure to market risk over five years.

Option 4: '0.32' — This represents a modest positive beta, suggesting Stock A is less volatile than the market but still moves with it. If the data showed relatively weak correlation or relatively low covariance, this could emerge, yet it would typically not be as small as 0.32 unless Stock A behaved quite defensively.

Option 5: '0.87' — A beta slightly below 1 indicates Stock A tends to move with the market but with somewhat less sensitivity. This value would occur if the stock’s returns track the market reasonably well but with dampened amplitude.

Option 6: 'None of the other answer options here is correct.' — This choice would be appropriate only if none of the listed beta values matched the computed beta from the spreadsheet. Since the prompt provides '1.27' as the answer, this option would be incorrect in the context of the given material.

Given the provided answer field lists 1.27 as the correct value, the evaluation would be that the spreadsheet’s beta calculation produced 1.27. If you had access to the data, you would verify by computing beta as the slope of the regression of Stock A’s monthly excess returns on the market’s monthly excess returns (or via covariance divided by market variance), ensuring consistent use of returns, risk-free rate adjustment if using excess returns, and the same time period and frequency as the data in the sheet.

In summary, the analysis of options shows that 1.27 is presented as the computed beta from the supplied data, while the other numeric options reflect plausible but different beta magnitudes that would result from alternative data patterns or miscalculations, and the 'None of the other options' option would only be correct if none of the numerical values matched the computed beta.
