Seeing how VOO and other US Index funds track A LOT of tech rn, what happens when tech pops and/or if they kinda just fizzle out? Has it ever happenned before that any big stock-sector just suddently died and that crashed the fund?
I lnow ot sounds silly amd that's why funds are used as a backbone for the whole bogglehead deal in case another crash happens, but i'm still wondering
