writing style... pounding head

i'm searching for articles related to the portfolio aggregation approach...
now then the search is very inefficient because i simply have that one term to search for -___-
it could be a many eyed monster with many names, so how??
so how??
currently listening to some house/tech stuff by a deustche man called Sash... now dear Sash... he's a good ol' fellow who has put together many lovely little tunes.. including this one with the japanese man talking away in it..

so portfolios eh? do u think sash could make a song about them?
hmmm......
