I think beta is calculated within a sector. So if beta stays at 1 then its equivalent to investing in the sector index fund if such a thing exist (not in nepal ofcourse). But mostly index fund i see are a best performing stocks in a exchange that are mix of different sectors.
Beta is just a measure of past correlation. it is not indicative of what the stock might do in the future.
theoretically, that is what should happen.
