What statistical tools does a analyst (financial) require? I just graduated in engineering where I have a very strong background in pure maths, but unfortunately I didnt study any statistics in my course. I know calculus, probability theory, measure theory, analysis etc. But I have not done any courses on regression etc.
I am planning to apply for several "analyst" positions at various banks/investment firms in the coming months.
Amongst some of them, they specifically require the applicants to have a good knowledge in statistics.
What statistical techniques/concepts do I need and should I learn (self study), that an financial analyst would require? Basically I will be analysing and computing statistical and financial data, what techniques should I learn? Should I start with regression, time 
series etc.?
As taken from wikipedia, this is something I would probably be doing:

Financial analysts use spreadsheet and statistical software packages
  to analyze financial data, spot trends, and develop forecasts. On the basis of their results, they write reports
  and make presentations, usually making recommendations to buy or sell
  a particular investment or security. Senior analysts may actually make
  the decision to buy or sell for the company or client if they are the
  ones responsible for managing the assets. Other analysts use the data
  to measure the financial risks associated with making a particular
  investment decision.

So what statistical concepts/tools/techniques/methods do I need to study, in order to do the above (in the quotes)?
I just got the book George Snedecor: Statistical Methods, but what main concepts/techniques are most important/most used by analysts? I'd like to quickly start into those topics first.
 A: Maybe you want to take a look in Statistics and Finance: An Introduction by David Ruppert. It covers a wide range of topics but none in detail. The author actually written this book with engineers in mind and it's very application-oriented.

A: Take a look at these lecture notes for Financial Data Analysis from University of Chicago's Financial Math Program to get an idea of topics. Rene Carmona's Statistical Analysis of Financial Data or Ruey Tsay's Analysis of Financial Time Series or An Introduction to Analysis of Financial Data with R might be good as well.
A: There are a number of statistics books targeted for business and finance.  You will find that they emphasize regression and time series.  In the case of financial data volatility is an important concept and so the more recent GARCH models that tend to be covered in advanced courses may be important.  When I taught business statistics I used an earlier version of this book by McClave and Benson.
Its table of contents should give you an idea of what topics are important in business and finance.
