BE rose ~20% before its S&P 500 inclusion was confirmed. What does history suggest happens next?

BE rose about 20% in the five trading days before its S&P 500 inclusion was confirmed, then another 5.4% after the announcement.

I looked at 63 historical S&P 500 additions. The median announcement reaction was about 1.6%, and names that had already run up significantly before confirmation tended to see much less additional benefit into the rebalance.

That doesn’t mean BE has to follow the historical pattern. Its own fundamentals, momentum and market environment matter much more from here.

Curious how others are thinking about the balance between the inclusion catalyst and BE-specific upside.
