Anyone who knows anything about investment banking knows that BILLIONS of dollars trade hands everyday, from institutional investors alone.
One of my best friends works for Commerzbank in Germany, and within his first couple years of college (so he was what, 20 or 21) had well over €1 million to play with DAILY. Investment banks have so much fucking money to throw around its not even funny. Hell, my cousin is an investment banker in New York and his boss made over $900 million last year on his salary alone.
Not saying this kinda stuff doesn't concern me, just saying that its easy to be taken out of context.
