Of course making money is always the key issue. That (not completely facetious) comment aside:
On the practical side, in many firms IT is struggling with being clear, transparent, and intuitive in their handling of multiple curves and their associated risks. Stumbling over your own systems is an annoying way to lose money. These risks can be surprisingly ...
Two Day-Traders went to go eat (after the market closed of course!). One of the traders orders a steak and has a hard time cutting it. He then asks for a sharper knife... when he unfolds his cutlery the knife hits his plate and falls out of the table and lands right by his foot which was slightly sticking out of the table. The other trader looks at him and ...
there is no stealing of data unless you delete it from the original source. Let me elaborate, as the semantics are very important here. Stealing, even with quotes around it, "Stealing" requires that something is removed from the original place. You steal car. You copy a file, as such data is protected via copyright when it can and other subsequent acts that ...
"Individual Craftsmanship"...I am not sure how you want to apply this skill set later. Craftsman to me means someone who simply applies a tool set, it does not imply (according to the dictionary definition) whether professionally to earn money or in order to teach or treat it as a personal hobby. So please let me comment on all three:
Professionally in the ...
While amsh's answer definitely gives you what you need for interview purposes, for any visual learners like me, here's what running through all possible paths ends up looking like.
Another thing I might consider bringing up in an interview context would be the intuitive reasoning behind why it works out this way. In other words, just explaining that a 15% ...
There are a few things:
Active absolute return managers tend to underperform passive benchmarks after fees. So if you can get a manager that can outperform a passive benchmark (perhaps who has a mostly passive strategy with some active tilts), then you are
Your scenario of a portfolio dropping 48% is not realistic. Most asset ...
The first reason is the answer to this question :
should I bother invest in your fund and not simply invest in the S&P500 etf ?
The second is :
Are you a fraud ?
If someone claims to use a long only strategy with stocks from the S&P500, you expect his fund returns to be correlated to the S&P500 to some extent. If it is not the case => fraud.
Summary Answer: Those are interested to benchmark against indexes who sell such index products (pricing data, trade marks, rights to use and publish), and of course portfolio managers because they look generally much better when indexed against indexes than when being assessed through risk-adjusted returns. The general public is sadly just too uninformed to ...
Some more references. Here are three starting books:

for risk + statistical approach: Risk and Asset Allocation, by Meucci;
for microstructure: Market Microstructure in Practice, by Lehalle and Laruelle.
As regards the free sources, the best place where you can find material about credit risk management is defaultrisk.com; it is a website where are collected (almost) all academic (and not) articles and working paper, references and researchers.
Moreover, as regards the forums, I think you should try visiting Credit Risk Group at Linkedin; it is a very ...
What are some indicators that a given security might be inefficiently priced?
What about efficiently priced (i.e., how can we estimate the
degree of information already baked into price)?
You would need to get lower level data than what was used in this paper that was referenced here. The MSF data is probably fine for the paper, but if you were to ...
You have a correct understanding. There is a subtle difference in that Knight effectively distinguishes uncertainty from chance. It could be argued that there is no such thing as chance in the Bayesian posterior density. To understand why, imagine that you were holding a strictly fair coin and you were going to gamble with an unknown stranger who would ...
If you would like to obtain a job as a quant first you have to pass a job interview in a company. During the job inteview you will be asked about basic math (derivative, integral, limit, etc.), stochastic analysis (martingale, Wiener process, Poisson process, etc.), ODE, PDE, SDE, risk measures, Black-Scholes model, short-interest rate models, Value at Risk, ...
The simplest workaround is actually to forget that Macauley duration exists. I actually feel very strongly about this: Macauley duration shouldn't be taught in school, should be mentioned only in passing in textbooks (if at all), and belongs only in the history section on Wikipedia.
This is because it's more or less useless in practice. When practitioners ...
The papers mentioned in Taleb's CV are not linked to actual PDF files.
To get them, an advanced search on Fooled By Randomness website will do the job,

The search can be refined for particular articles.
I have heard good things about Epps but haven't read it. Hull is aimed at less technical people and can get a bit turgid.
I have my list of recommended books with discussion at
