Analyze tracking errors between ETF and stock market index in the last decade

5571521786922_.pic_hd.jpgSummary: In this article, under the context of Hong Kong’s Mandatory Provident Fund scheme (MPF), we find that some Exchange Traded Fund (ETF) occupy large holdings in a particular MPF fund. By calculating the tracking errors over the past ten years, the year of 2008 stands out with the highest tracking error, which corresponds with the global financial crisis. In other years with more stable stock markets, ETF performs relatively well. We also calculate returns between two ETFs and the indexes they track respectively; the results turn out to be different.

We use Python as a calculator, rely on pandas to read csv files downloaded from Yahoo Finance, and time series to present data in the form of charts.

Background

Hong Kong has a rapidly aging society. According to the Population Projections released by Census and Statistics Department, HK is expected to have a third of its population that aged 65 and above by the mid of 21st century. There is a growing concern over the issue of social security especially for the elderly, since the burden for the employed population in the future to take care of the retirees will be unbearable.

轉載:如何標準化數據可視化之「美」?

轉載自 全球深度報導網 Repost from Global Investigative Journalism Network (GIJN)

Original Article(本文由簡體中文轉爲繁體中文)

媒體在數字化轉型中,越來越多地用數據可視化作為呈現方式。但許多可視化的作品只是追求形式上的美感,沒有實現數據可視化真正的功能:清晰有效地傳達信息,使讀者更形象地理解數字背後的含義。媒體推出的可視化新聞良莠不齊,水準忽上忽下,卻少有懂行的同行或讀者給予反饋。本週的數據新聞給讀者介紹由Perceptual Edge網站創始人、信息視覺化專家Stephen Few提出的一個標準化衡量規則,評價可視化是否達到了必要的效果。

Few認為,標準化的規則能讓大眾針對同一個方面給予評價,而不只再用空泛的語言描述一些模糊的印象。他認為,可視化的效果分為兩大類,分別是信息豐富性(Informative)和情緒感染力(Emotive)。前者考量的是數據可視化能讓讀者接收到多少信息,後者則衡量能否讓讀者產生一定的情緒反饋。在這兩大類之下,還有七個細分的小標準。信息豐富性涵蓋了五個維度:實用性、完整性、讀者接受度、真實性和直觀性。情緒感染力有兩層含義:一個是美感,另一個是用戶參與度。

Data News of the Week | U.S. Gun Control Debate and the Media

There were more than four months after the 2017 Las Vegas shooting, which is the deadliest mass shooting* committed by an individual of the States. As the largest gun-holding ratio (per capita) country around the world, USA has long been debating the gun control, yet, no consensus has been able to achieve. That’s also why media play a huge role in formulating the public debate and policy-making of gun control. We will discuss the two following reports by BBC (America’s gun culture in 10 charts) and The Telegraph (One mass shooting every day: Seven facts about gun violence in America) to illustrate the strengths and limitations of media coverage on the gun control.

*Mass shooting: When an attacker killed three or more victims in an indiscriminate rampage. Before 2013, the number was four. Continue reading “Data News of the Week | U.S. Gun Control Debate and the Media”

Data News of the Week | Trump Lies and His Job Promises

It has been more than a year under Donald Trump’s administration. Trump has made a lot of groundless claims and job promises which happen arbitrarily. Some newsagents keep a record of it and visualize the frequency. To criticise the act of the president in a more grounded way, The New York Times compares the lies frequency between Trump’s and the former president Barack Obama. We also dug deeper into one of his promises in his election platform which is job creation and employment enhancement. From which, we adopted a project from ProPublicaThe following will discuss the visualization, the use of words and the effects of the two projects.

The Rise and Rise of ICO in late 2017

If you still don’t know what is “blockchain” or what is “bitcoin”, The recent work from Max Galka will assure you this is the high time to do some self-study, or you will miss the birth time of “another Internet”. The idea of ICO, Initial Coin/Chain Offering, is an analogy of IPO. With the inception of “smart contract” capability, fundraising, a process to exchange currency to certificate, can be done in a distributed manner. The “currency” in the chain world can be Ethereum, NEO, BitCoin, … The “certificate” in the chain world is called “token” so the ICO process is also referred to as “token sale”. The convenience of ICO gains rapid growth with crazy capitals pouring into this field. Just check out this interactive/ animated token sale history.
