Can someone confirm the correct Jensen's Alpha formula? I've seen two versions used throughout the material and I don't understand why. Maybe I'm just overlooking something. One version adds the Risk Free Rate to the Price of Risk while the other one subtracts it. Examples below

Version 1 = Expected Return (portfolio) - (Risk Free Rate

**+**Beta (portfolio) [Expected Return (Market) - Risk Free Rate]

7:12 minutes into the Instructional Video: Amenc, Chatper 4.

Version 2 = Expected Return (portfolio) - (Risk Free Rate

**-**Beta (portfolio) [Expected Return (Market) - Risk Free Rate]
