Beta as described: Standalone risk, or not?

The intro to this article very clearly states:

Beta is important because it measures the risk of an investment that cannot be reduced by diversification. It does not measure the risk of an investment held on a stand-alone basis, but the amount of risk the investment adds to an already-diversified portfolio.

However, the Estimation section goes on to say:

The relative volatility ratio described above is actually known as Total Beta... Total beta captures the security's risk as a stand-alone asset..., rather than part of a well-diversified portfolio.

So, which is it? — Preceding unsigned comment added by Kronn8 (talk • contribs) 20:35, 16 February 2019 (UTC)
