Was reading the wiki on QQQ and stumbled upon this:
The only time the index is to be rebalanced again is if:
One company is worth 24% of the index.
Those companies with a weighting of at least 4.5% constitute 48% of the index.
That latter condition is kind of close to being met, but what would happen if triggering a rebalance resulted in that condition being met again? Doing another rebalance wouldnt change anything in that scenario. Would they just live with it?
