@Dr.Dung, if that Tien Dzung is you, do you use astrological forecasts for the Vietnamese stocks?

@giangle

no, i'm not good enough to do that

the funny thing is that I met a few people in VN who used "phong thuy" to predict the stock market

Well, you never know. Since everybody is speculating, it may be a strategy to try as many others. If they end up beat the market, probably not because of "phong thuy" though .

Mr Dzung,

I know that there is no short sale in VNmese stocks, but since your company has many clients' shares, can it borrow those shares and sell short(like the banks that take the short deposits of clients for long term lending)? With such capacity it can always return shares to clients when needed.

You are a famous mathematician and now are a director of an IPA's division, do you still work as math prof? How do you compare the two jobs, what is more challenging or interesting?

Thanks

i heard that you could short the vnindex & some VNese stocks with an offshore account, though we never tried that

I really like the idea of using "Phong Thuy" and astrological forecasts to predict the stock market since they certainly correlates to human behaviour.

However, the (quant?) questions among many others are: how much they are correlated?, what are the affect lag time and the appropriate investment time horizon? ...

Hi, I'm a new comer. I've been doing some studies on anomalies in Vietnam's stock market and found very clear evidence of weekend effect. However, as far as I know, weekend effect is mainly explained by shortsellers' behavior. Can anyone give me an idea on this problem? Is there any chance that securities companies are using their cusomters' accounts to bet on the downside potential of the stock market?

Hi walker,

It is interesting to learn your finding about stock return anomalies related to weekend effects. I would love to read your finding in more details if you are willing to share.

regarding the weekend effects, how did you define monday return? also, if possible, please check if the anomalies are different between before and after Feb. 2007. it is also a good idea to trim out outliers (e.g. remove those in the top and bottom 10 observations in term of return) and see if your finding is still consistent. I expect to see different results.

Hi ngtridung,

Thanks for the nice idea of trimming out outliers. I'm quite busy now with the graduation thesis. Be back with this study soon and share with you the results.
