Have red two books recently, but would like to just do a quick summary but not thorough analysis here, as I shouldn't have put too much time on here. May re read them in the future.
1. Freakonomics by steven d.levitt and stephen j.dubner
- Peel off one layer or two of seemingly logical "common sense" by applying statistical tools of econonics to determine the direction of correlation and discover hidden links.
- Human works for incentive and that's what economist interested to figure out and model it, from micro to macro.
- Examples touched on:
a) school teachers - cheating?
b) sumo wrestlers - match rigging?
c) Ku Klux Klan - incoherence of roles exposed lead to its demise
d) real-estate agent - incentives work against you?
e) drug dealers - except the top mafias, most don't earn enough, but endure and hope to make it big one day
f) criminal rate fall - self-contradicting explains from so-called experts and hidden link with abortion legalization
g) parenting - does nurturing / parenting really matter?
2. The origin of brands by al & laura ries
- A fascinating book from marketing gurus that build its theme around the law of natural selection in business world - divergence. It argues that like natural selection, products and brands expand in such a way that split into more and more branches, instead of convergence. This book gives a lot of examples and it's definitely eye-opening even though you may not agree with the central theme 100%.
- Different technologies do not converge, but each technology split further into more sophisticated field to cater for niche market.
- Convergence may not always fail when value of convenience are created but convenience only has small roles to play in the overall business market.
@@@@@@@@@@@@@@ Welcome! 欢迎!@@@@@@@@@@@@@@
Welcome to my virtual home. This is a little private space for me to put my thoughts and share my feelings since 2005. Due to my wide range of interests, there are perhaps too many tags. I would explain some of the less obvious tags:
"About Life" is really about how I have been pondering about life and what enlightenments and paradigm shifts I had experienced.
"About Psi" contains most topics about happiness, optimism vs pessimism,
confidence, comparison, pride and prejudice and other psychological aspects.
"About Logical Thinking" is about my own way of interpretating and explaining
certain issues, aiming to debunk (or create?) superficialness of them.
"About Ideology" is about my thoughts on big concepts like freedom, justice,
fairness in society and religion.
"About Society" is more about my observations about the society, often through interactions with different peoples.
"My Country" reveals my frustration, critics and hope
on my homeland - Malaysia.
"My Little Pieces" has more short posts though mostly are written in Mandarin.
While I do have some posts on book reviews and business, I am planning to
separate them into author-specific and content-specific blogs. Stay tuned.
Enjoy your reading!

Two useful sites for investment knowledge
These two local sites can help you to grasp solid knowledge and insights about investment ideas and tools.
http://www.moneytalk.sg/
http://www.wisewealthbook.com/
There is another book that I recommended to another friend who asked me on how to start studying investment. You can borrow it from any library.
"Financial services in singapore - Tan Chwee Huat"
Sometimes I feel like sharing out of what I have learnt but I think at this infant stage, I would be better off spending time to read and absorb instead of writing out to share. Without the vast knowledge and experience, my work may look like a rubbish as compared to those blog articles.
And hence, I recommend you to read both sites as the starting point of your endeavour, if you, too, would like to embark on the same quest.
Currently I am reading on ETF, while some friends are studying CFD and options on equities. Looking forward to leverage the knowledge gained across.

古人管理之道
加强和辅助管理的工具多不胜数,但我总觉得,能用工具而不去深究道理的,只是工匠,而非大将。无心于道,再多的术也是徒然,能学不能精。
或许我有偏见,趋势读了MBA的,可能还不如稍懂中国历史的更懂得管理。古人的智慧,顺手捎来就能当管理的金科。一句“得人心者”,可得天下;一本资治通鉴,可治天下。
知人善用
赏罚公平
轻重分明
职责明确
传交有序
刚柔并济
软硬兼施
【这篇文章和这些总结,憋了很久才在今天写出来。现时的我只能空口说,但我不害怕证明自己,当机会到来时。】

转载:模糊理论与投资本质
【读感:写得挺好的……就算所用的类比未必完全恰当(实际上有哪个类比不能被挑不可比性呢?),仍能带来启发。善于从实际经验中总结出成功的战略,确实是最关键;至于技术分析(Technical analysis)和避险操作(Risk management),尽管我还未深入了解,但我相信仍有其可取之处。】
模糊理論與投資本質
陳信得 投資生活家
本期發刊日:2005/06/13
在跟一位醫生談起中西醫的優劣點時,結論是兩種醫學體系各有優點。因為,中醫強調整個系統的關聯性,因此不會有著頭痛醫頭腳痛醫腳的問題。而西醫則強調實驗與科學性的證據,不會以無法驗證的理論作依據,而是透過扎實的驗證所以可以持續的進步。然而,西醫的最大問題就在於由於人體太過奧秘複雜,因此無法發展出一套涵蓋諸如穴道、氣、五行、、等等可以完整解釋的系統來。然而,雖說這兩種醫學體系都有著其結構性的問題,但卻都能夠幫忙人們解決大部分的治療問題。
這種現象有點兒像現代科學的渾沌理論(Chaos theory)與模糊理論(Fuzzy theory)。因為,這兩種理論街受所謂的模糊現象的存在,偏重人類的真實經驗,而不主張用繁雜的數學分析模型來解決問題。並且運用機率、多值邏輯來說明解決問題,而非傳統的笛卡耳二值邏輯。換句話說,就如同諾貝爾得主波耳的不確定論一般,提出人類永遠無法真正知道基本粒子的真正位置與方向。換句話說,類似這種跟造物主投降強調人類的有限而無法全知,竟成了現代量子物理學的基本概念。而事實上,現代中西醫學也同樣以這樣的真實面貌來昭告人們醫學的有限性。
雖說,現代科學中的尖端物理學與醫學已經宣告人類相關各種知識的有限性,但在投資世界中卻有著不少專家與學者仍然抱持著科學、知識至上的觀念,想強行解釋、預測攸關投資的各種現象與變化,而其中最讓人印象深刻的就是技術分析與避險操作。技術分析的基本假設就是萬事都有固定的週期與變化模式,意即未來就是過去的複製。所以,技術分析的計算交易資訊都是過去的資料,諸如過去一年、一週一月的成交價、成交量。而後再將這些資料用所謂的數學模式來計算,並加以預測未來變化。技術分析看起來洋洋灑灑道理與公式一大堆,但是成效到底如何呢?只要看看外資法人對於個別股票價位的分析與預測內容,就會發現這些專家根本沒有人將技術分析當作一回事。因為,我們從未聽聞外資法人有著諸如『聯電帶量突破二十元後就會上漲到30元即50%的技術關卡』奇怪說法的。
至於,近幾年大為風行的避險操作與避險基金,號稱利用各種高明的數學模式可以使得投資人迅速獲利,這一年來只見虧損累累。事實上,這種操作正如使人迅速獲利但也曾使得很多人或基金一夕之間發生重大虧損,也沒有什麼可傲人之處,反而看起來跟賭博沒什兩樣。因為,一般常見的賭博的賺賠也是如此起起伏伏無法長久致富。
事實上,渾沌或模糊理論觀念的核心就在於這世上有很多事是人們無法清楚釐清其中的因果對應關係。然而,這種事實卻無礙人們可以持續進步、成長與致富。就以投資世界而言,根本不存在諸如端午節效應、經濟成長就會造成股價上漲等簡單的因果關係。因為,每一年的端午節都有著許許多多的因素影響著股價變化,而且每年的影響因素也不盡相同。因此,投資人去預測或分析這種關係實在沒什效益與效果的。
雖說,正如模糊理論所言,單純的數學模型無法解決複雜問題。然而,波耳的不確定論卻又提供一個樂觀的解決方案,那就是即使人們無法了解或計算出每個基本的粒子的動態與位置,但卻無礙人們運用這科學現象來提出革命性的新產品造福人類。而真實投資世界恰如真實的量子世界一般,它不存在單純因果或二值邏輯的架構,但人們卻可以利用過去成功的經驗如同模糊理論般加以運用而致富。所以,如果投資人想要在投資世界中如同投資大師般常保獲利,那麼就應該善用他們的成功經驗來投資致富。而不要妄想如同技術分析或避險操作般,想運用數學模式來投資致富。因為,這種做法的下場是可以想見的。

小小想法
想当然而……我觉得
投资就好像出海捕鱼,你永远得冒着没顶的危险,所以每分准备都不能少,每份收获都是恩赐。
投资就好像武术,宗派林立各有特色,如何海纳百川自成一派最重要。

Book: Wise Investing Made Simple
[Wise Investing Made Simple - Larry E.Swedroe]
I am putting what I understand from this book, by picking up meaningful sentences and restructuring it accordingly. I don't know if I am putting too many sentences here, but it's a good book that worths your time, so go borrow or buy and read it.
I drafted my originial summary last October accordingly to Chapters.
This book is pretty easy to read with good analogies.The author has strong belief in "passive investing by building a globally diversified portfolio". He builds his arguments around two central themes:
1. Efficient Market Hypothesis (EMH)
- Efficient market is a market in which trading systems fail to produce excess return and it is difficult to persistently exploit mispricings. Everything currently knowable is already incorporated into prices.
- Even the market is not perfectly efficient, it's close to. It is not impossible to uncover mispricings (incremental insight), but cost of efforts are likely to exceed the benefits.
- Successful trading strategies self-destruct because they are self-limiting
2. Risk and expected return should be positively related
- Value stocks are stocks of risky companies, hence it provide large and persistent premium over growth stocks to compensate the risk.
- High price reflects low perceived risk, and thus low future returns should be expected.
From these, he thinks that
- Active investing is loser's game. The odds of success by competing against the collective wisdom of the market are so low that it is imprudent to try. Of course there are survivors, but is it by skills or by chance? It's purely random. Outstanding performance does not persist. As an evidence, the top list of funds or top fund managers are different each time. Will you believe that there are coin-tossing gurus?
- Active investing is myth created by Wall Street because broker earns no matter you win or lose. Brokers make the overall game a negative sum game. They made active investing exciting but investing, however, was never meant to be exciting. It is meant to be about providing you the greatest odds of achieving your financial goals with he least amount of risk.
- Most market forecasts are based on economic forecasts and economists' forecasting skill is about as good as guessing. Investors should treat economic and market forecasts by so-called "experts" (gurus) as investment graffiti - the only value they have is as perhaps entertainment. And "You make more money selling the advice than following it." [Counter? Isn't him one of them?]
He also debunk the following myths:
a) Stocks in the long run will surely earn - Stocks are risky no matter the length of investment horizon. And that's exactly why its returns are high. [Counter? It is not about how long or how short, it is about timing. But then again, how do you know?]
b) Buy what you know - Familiarity breeds investment by creating an illusion of safety. People over confidently confuse familiarity with knowledge.
c) Buy what everyone knows - Mistake of confusing information with knowledge that you could use to generate above market returns. Trends tell little about future profits. Demand may rise but market can be over-supplied.
Whether you believe in passive investing or not, two important advices are:
* There is nothing new in investing, only the investment history you don't know.
* Never treat the highly unlikely as impossible.
Great examples are:
# The Nikkei index hit 40,000 in 1989 and now it's below 10,000.
{Fueled by low-interest mortgages, real estate prices in Japan had risen so high that by the end of the 1980s just the land under the Imperial Palace in Tokyo was nominally worth more than all the real estate in California. Then, in late 1989, the bubble burst and real estate prices plummeted, leaving Japan's financial institutions saddled with toxic mortgages and facing bankruptcy.}
Read more.
# In 1900 the Egyptian stock market was one of the largest in the world. Now it's no where. {It was public knowledge that when lumped together, the Cairo and Alexandria Bourses rated among the world's top five Stock Exchanges. Egypt's economy was at an all-time high and the number of companies traded in the Cairo Bourse alone had reached 228 with a combined capital of 91 million pounds.
But like the swing of a pendulum, the high state of euphoria disappeared overnight. Prudence having given way to high-risk speculation, what had started out with a real estate boom in Egypt, ended in what became known in the annals of speculative history as the Crash of 1907.
Some historians concede that the money panic of 1907 started in Alexandria, Egypt, with the failure in July of a large bank - Cassa di Sconto. Japan was hit next, then Germany, then Chile. By October, the fallout reached Europe and the United States. In Egypt, the overextended banks folded up one after the other. }

The First Step
From this moment on, I will start to write something about investment. This is not because I have mastered it and can start giving lectures, but on the contrary, I have just made the first step and like to save my knowledge gained and observance along the future journey. I do not mind if you find my "eureka" moments are like "what-so-big-deal" or "so-what", as everyone has their own journey to explore. I would feel glad if you could grab something out of them, and even better if you could share out yours or point out my mistakes or misconceptions.
The first step has always been important, and subsequent few steps are even more important as they serve as the soil to grow. A rock solid foundation is the key to everything. I feel sorry to my partners that you may find me like to dilly-dally, talk more than walk or putting more emphasis in other aspects, but this is really my style. I always want to change, and in fact, I am the greediest one who want to change to become better in every aspects, but I believe there is a right time for every change, risen out of the need or consequences. Before I could sense that the moment has come, I preserve my determination and keep my memory well. But when I finally sense it, and I say I want to change, I do really mean it. The dilly-dallying is just the prelude for the main plot. Just like my English, like my Excel skills, like my emotional balance, like my expense management, like my exposures...(Oh...I don't mean to brag...please forgive me)
I am setting my mindset right first before stepping out. To me, investing is just a tool to set myself free financially to move on to do great things; no doubt I need to know how to excel in using this tool but I would not like to see myself get addicted into numbers and alphabets at the expense of life's balance and beauties. That is easier said than done as consequences do change people and money has the cunning power to twist even the purest soul, so I am putting a reminder here for myself, for myself in the future.
I shall now begin to walk, and talk the walk.

Entrepreneurship
I am actually reading materials on the topic of "entrepreneurship" on-line, as part of my preparation for ENS. I've been linking contents from lectures, questions from assignments and pass year papers, and also web sources to predict what sorts of questions could be asked. I've got a flow chart in my mind but I shouldn't bother you too much with it.
"Entrepreneurship" has become a buzz word for new generation like us. We are fascinated by the success stories of Google, Facebook, and bla. We imagine ourself to emulate their success (at least for one second), craving for the "great superb fascinating idea". In fact, quite of a lot of us had at least took some actions. But how many of us will succeed in the future? To answer this question, we need to understanding few things.
Firstly, are entrepreneurs born or made? The same old debate of nature (heredity) and nurture (environment) applies to this context too. Both are essential but which factor is more important? Personally I think environment is way more significant. What you believe now is shaped by what you had experienced from the past.
Secondly, assuming entrepreneurs are bred by circumstances, what is your drive to achieve success and how strong it is? For people with backgrounds like us, that leads to two possible scenarios and reasons behind:
Scenario A: Tried out on few ideas but failed to create big success. Motivation eventually faded off and thus giving up the idea of becoming entrepreneur.
Possible explanations:
- The true reason behind to become an entrepreneur is not strong enough to keep motivation high. Why do you want to an entrepreneur in the first place? Money? Success? Do not want to work for others? Want to help others? Better future for kids? Can benefits from fulfilling this desire exceed all possible costs?
- It's hard to get out from comfort zone. For most of us that are going to finish tertiary education and graduate soon, we didn't grow up in a harsh upbringing. We never experienced famine so we never really appreciates food. We never experienced poverty so we never really appreciates money. We take a lot of things for granted. I am not saying that we are living in a wrong way but that to a certain extent reduces our alertness and weakens our drive.
- "If you have nothing then you have nothing to lose". For many successful entrepreneurs, entrepreneurship is their only opportunity to establish themselves in the society. For us, it's just one of the choice. The difference in mentality, desire and motivation couldn't be greater.
Scenario B: Successful entrepreneurs.
Possible explanation: Needless. Meaningless.
My opinion is that default scenario for us is scenario A. How to reach scenario B? If only we have a burning desire for this, at the expense of other life elements. And then a totally new mind set. Environment that had brought us up may be a curse in disguise if we don't aware of our own weaknesses.
But anyway, be entrepreneur or not, I believe that all of my friends will have a bright future. Cheers.
