1. Don't cry because it's over. Smile because it happened. 

Well, it was fun while it lasted.

Index-rebalance strategies, the talk of the town just a few short years ago, are seemingly on their last legs these days. 

The strategy, which amounts to betting on stocks being moving in and out of popular indexes like the S&P 500, hasn't been generating close to the returns it once minted for multi-strat hedge funds.

Now, some firms are cutting their losses and moving on, Insider's Alex Morrell reports. That's meant portfolio managers who were previously fawned over are now heading for the exits.

In this town, your luck can change just that quickly.

From Citadel to Millennium and Point72, Alex has a list of nearly a dozen PMs focused on the strategy who have departed this year.

What doomed the index-rebalance strategy is a tale as old as time on Wall Street. A handful of firms figure out a way to make money. Everyone else catches wind. And before you know — zap — that opportunity is gone faster than you can blow your bonus on a summer house. 

Of course, every end is a new beginning. Times are tough now, but as Alex notes in his story, not everyone is completely giving up on the strategy.

Because if Wall Street has taught us anything, it's better to get in at the bottom than the top. 

More on the no-good-very-bad-year for index-rebalance strategies.
