Interesting, so you are redefining the word stockbroker to include all roles that do NOT involve stockbroking? Nice. And even further you've gone on to explain to me how your incorrect interpretation of the industry is the right way to look at things.
Let's get some rudimentary definitions out of the way:
"A stockbroker, also called a
Registered Representative, investment advisor or simply, broker, is a professional individual who executes buy and sell orders for stocks and other securities through a stock market, or over the counter, for a fee or commission. Stockbrokers are usually associated with a brokerage firm and handle transactions for retail and institutional
customers."
A quant:
"A person who analyses a situation or event, especially a financial market, by means of complex mathematical and statistical modelling."
A trader:
"A
trader is person or entity, in
finance, who buys and sells
financial instruments such as stocks, bonds, commodities and derivatives, in the capacity of agent, hedger, arbitrageur, or speculator."
Now, tell me, what does a Quantitative Analyst working on a pricing model for a new strategy in a quant hedge fund have to do with Barry at an IDB (e.g. BGC, ICAP) calling up his buddy Steve (the trader) at GS to help execute a large block trade so that he can shave off some commission off of Steve and probably meet up with Steve later for a boozy one in Mayfair? Nothing.
Try again.
