I guess your boss will reply: the expectation of a martingale is its present value.

Why Shreve's is such a good book is because it has an excellent balance between theory and examples (and very gentle explanation). If anyone has any experience in trying to read those treatises in the most abstract branch in mathematics, with utter abstractness and conciseness, you will love the...

The best education is get into the market. But you said you got a job offer and still needs interviews? What do you mean "final attempt at MFE education"?

I don't really mind which company produces the software, as long as the software is useful and "well-behaved"...

BTW, as you had mentioned it I just realize I didn't get any crash or 'frozen' issue so far which was really the trademark of windows... Windows 7 does improve a lot to be fair

I used Mac for several years and turned to Windows 7 (dual boot) few months ago, so far I am satisfied with my windows experience... the main problem I had with Mac was the lack/compatibility of softwares which are popular in the PC world, I still remember several frustrating moments which I...

An entry level T420 is priced (without coupon) a couple of hundreds cheaper than the MacBook....

I am still having hard time using the trackpoint...isnt it hard to adjust or am I not yet getting the "feel" for it? Apple's trackpad is simply the best. I can used my MB smoothly just using the trackpad alone without a mouse, but I can't speak the same for other laptops. I'm still stunned by...

another point: the machine is surprisingly cool even running some heavy applications for long time. I don't know why it is not taken as selling point (only discover it after few days of usage) as I have some bad experience with other laptops that can really be used to cook.

MC method for American option is non-trivial. What methodology did you use?

MBP was one of my considerations but have ruled it out because of its price (for the same configuration with T series). Also I have a MB (quite old model) and my desktop is an iMac, so I don't really need another apple product line... so far very happy with my new toy and is playing around...

That's great choice, Andy. However I am outside US so there aren't many options.. it took me quite some efforts to search around for bargains already and the machine is priced very competitively in US compared with other countries

I got the one with i5, 8G RAM, 320G7200, but feel a bit pity that the screen is not 1600x900, it's configured so can't be changed...But overall I am very happy with it, actually feel quite surprise for the quality. I haven't seen the real T420s but from what I know T420s is slimmer and lighter...

I just received my T420 today... With all respect the machine makes me feel like all laptops I have ever owned look like buying from Toysrus...I bought it from other online outlets and there are quite few bargains around...should check if you want one. This is my first tp and I love it!

Have you bought you new toy yet?

The book "Implementing Derivatives Models" by Clewlow and Strickland might be a good source

This is one point that I want to try thinkpad: its toughness. Don't need to worry about my machine anymore when carry it around

Really tempted by this machine. It got prefect specs for my need and look rock solid! this would be my first thinkpad so want to get some idea from people from quant industry

any reviews?

"Let me give you an example: a good friend of mine interviewed with Algo Trading desk of a major European bank in HK. He's top-notch, but had no prior programming experience." So what does you friend study?

If you're going to StonyBrook for PhD you should meet people here http://www.scgp.stonybrook.edu/ especially the donor

Compared in terms of 1. skills set, 2. money, 3. reputation, 4. potential in the future? Assume both are quantitative oriented.

Let's take Hull's as an example (I choose this just because it is so widely used. I like the book myself and nothing against the author). Assume each class can sell 10 of them and it is used not just in US, but around the world, so I think it wouldn't be too exaggerate to assume there are 1000...

How much people can make if they publish a well-known textbook like this one or Hull's? Is it lucrative? There is new edition every 2 years, especially those well-known undergrad books.

You need the boundary condition, i.e. the payoff function, to start off the calculation. Read the method carefully. x is the underlying asset.

The N-1 term appears in variance instead of sd? N-1 is used instead of N because N-1 will make the sample variance unbiased.

I understand your frustration with Chinese "modern culture". However I am sure there are many talented people out there, some of them lucky, some of them not that lucky, and these above average people are waiting or already actively pursuing opportunities outside their radius. From what I have...

May be the quote I used was misleading. I didn't mean to specifically addressing Tao when I wrote that. What I meant to express is that there is higher potential for talented people to standout if there is right environment for them. BTW Tao obtained his PhD in Princeton and showed great talent...

I think what others have been saying is that if you didn't receive very positive reply from other interviews or even has difficulty in getting an interview, then you better accept the offer. It is better to get in the door at least. However if you feel OK in other interviews and interviews seem...

This is true. Most of the well-known scientists with Chinese ethic are somehow have connection with the US. I believe it is the system of the country that matters. Talented people need freedom for them to blossom. However given the massive population of China (it is a common mistake to think...

@DominicConnor it's an interesting article. I'm quite surprised to know that there are more quants in NZ than Japan in your database. could u share with us roughly how many quants are there in different Asian cities?

It's quite off-topic and I'm afraid the conversation is starting to get more and more silly.

I have few friends who work in Japanese banks. These banks are not that generous in terms of compensation. Also they tend to put some constraints on you which may seem a bit inflexible. However Japan itself has a lot of interesting culture/traditions and people are very civilized.

Just curious what are the professional topics?

ThinkDifferent has a point.

Mandarin is used in China, Taiwan, Singapore and Malaysia, and people speak in Cantonese is likely to understand Mandarin as well, so Mandarin is the way to go. However for foreign people (especially white), it's not a good idea to speak fluent Mandarin, just basic is enough. By knowing some...

It may happen. In the very long run, it's possible that it may not even be useful in knowing Mandarin because Chinese people by that time will mainly speak in English and I'm afraid if you speak "too good" Mandarin you'll be looked down by those people.
