it's really less a "manipulation" event than it is simply the math behind mkt cap weightings.

the NDX is the top 100 by mkt cap (non financial).
every year at this time, they reweight the NDX (and at other times too, but not as many as they do at this time).

the SPX has had more changes this year than normal, but there supposedly was a lot of pressure to take out the microcaps out of the index (ie, BS), since SP500 is supposed to be a large cap index.

there is less subjectivity in picking NDX components than SPX, top 100 is top 100.
