Summary: 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.

Summary: In this article, we crawl and analyze the top 250 films evaluated by DouBan users, find their preference on specific directors, types and regions, and also see trends of movies in different regions, particularly in America and Hong Kong.

In general, the best ways to reflect a movie’s preference and prevalence are through box office and ratings. But box office is biased since lots of movies are blocked in China and people are likely to be affected by several factors. Thus, it’s more objective to examine it through ratings.
Douban Movie is a famous Chinese film rating site, with millions of users watching, rating, and commenting on movies day by day. Considering a large number of Douban users and the relatively objective measurement, data from the Top 250 list is suitable for our analysis.

Tech-savvy readers can jump to the database directly. Like before, the dataset is modelled as a graph, namely treating the Officers, Intermediaries and Addresses as nodes and their relationships as links. Neo4j is one widely adopted graph database. Its web user interface, called “neo4j browser”, allows journalists to visually expand and explore a graph. The query language “Cypher” is a superset of relational query (SQL), full-text search and graph pattern matching. Its flexibility and built-in graph algorithms allow experienced journalists to systematically study the underlying graph. The download page on ICIJ includes snapshots of four neo4j databases exported in CSV format.
