Unlevering and Relevering beta when Levered Beta is readily available on Bloomberg/Yahoo Finance?

Quick question here. In interviewing prepping, I have come across the idea that to calculate a company's levered beta you must look at a universe of comparables, unlever their betas, take the median, and then relever it with your target company's cap structure.

This makes sense, but my only question is why would the hell would you go through that trouble if levered beta for the target is readily available on Bloomberg? Is Bloomberg's figure inaccurate in some way?

Let me know.

Thank you, that makes sense. I was scouring the internet for an answer and was unable to find it. Might be an indication that it was a stupid question lol.

The levered beta you see on bloomberg is an estimate based on historical returns against the benchmark. Stock market returns are very noisy, so the beta you see on there is not the most accurate, just look at the standard error of the bloomberg beta to have the proof.

The idea of taking the comps’ unlevered beta is that you increase the sample size due to a larger number of firms that are hopefully similar enough to your target. Therefore, this estimate is likely closer to the “real” beta of the company simply due to less noise in the estimate.

Also, this measure of beta is closer to a long-term estimate because in the long-run, companies become mature and start to look and operate very similarly, so you can make the argument that the beta of the comps is a close estimate to a long-term forward looking metric, which we need for a dcf (dcf looks at long term average cash flows)
