There's an interesting shift happening in the S&P 500—companies aren't staying put in the index as long as they used to. The average tenure has been shrinking, which signals some real changes in how capital markets work.

This trend tells us something bigger: market rotation is accelerating. Whether it's due to tech disruption, changing investor preferences, or just the brutal pace of modern competition, blue-chip status isn't a lifetime guarantee anymore. Companies face constant pressure to adapt or risk getting cycled out.

For traders and investors, this is worth paying attention to. It suggests the traditional "buy and hold" landscape is evolving. New players are breaking in faster, while legacy names are losing their grip. The same principle applies across crypto markets too—velocity and innovation trump stability more than ever.
