I used to think this but then realized, active fund managers who don’t understand Tesla (most of them) will want to add TSLA to minimize their risk against the index and then try to beat the index with other positions that they do understand.I think you're misunderstanding what benchmarked against means.
It means they want to beat the results of the index.
Why would you mirror something you are trying to do better than?
They held 0 TSLA because they felt it would not help them BEAT the index results.
If a managed fund that charges significant fees were to report "Hey we exactly matched the returns o a passive S&P index fund!" their customers would wonder WTF they're spending their money on with those fees.
Buying into stocks NOT in the index is literally the only way to beat it
Again- how does that make any sense?
At that point they're just a passive index fund- not an actively managed fund trying to beat the index.
If you want to BEAT the index, mirroring it is exactly the way to insure you fail at your one job.
So pre-inclusion, an active fund manager either thought TSLA would do worse than the index as a whole, and bought 0.
Or she thought it would beat the index as a whole and bought shares (see ARK as the most obvious example of such a fund).
The same is true post inclusion.
