Task prompt

What the agent was asked to do

The client is looking to execute our rebalancing recommendations. Identify the stock with the highest Absolute Beta Reliability during the worst 10 trading days in Q3 2025, defined as the worst 10-day cumulative return of the F&B Sector Index. For each stock, compute: - Beta Predicted Return = Beta Coefficient × 10-Day Return of the F&B Sector Index - Absolute Deviation = |Stock 10-Day Return − Beta Predicted Return| - Absolute Beta Reliability = 1 − (Absolute Deviation ÷ Stock 10-Day Return) Reply back to me in a message with the company name, and the highest Absolute Beta Reliability and its Absolute Beta Reliability value. Round numbers to four decimal places.

Grading rubric

Criteria and grader verdict (showcase run)

States that the company with the highest Absolute Beta Reliability value for the worst 10 trading days of Q3 2025 is PepsiCo
Fail
Evidence: <TEXT_RESPONSE> says, “Monster had the highest Absolute Beta Reliability: 0.9086.” Assessment: The criterion requires stating that the highest Absolute Beta Reliability company is PepsiCo. The response names Monster instead, so this fails.
States that PepsiCo's Absolute Beta Reliability value for the worst 10 trading days of Q3 2025 is 314.3131%
Fail
Evidence: <TEXT_RESPONSE> says the value is “0.9086.” Assessment: The criterion requires stating PepsiCo's Absolute Beta Reliability value is 314.3131%. The response provides neither PepsiCo nor 314.3131%, so this fails.
