Investing in Singapore


The main index ETF (What is an ETF?) in Singapore is the one that tracks the Straits Time Index SDPR STI, which lists 30 Singapore blue chips.
The STI went down recently (over the past 2 months) therefore it would look like a good time to buy. 

Other indexes available in SG:
  • US: tracks the US S&P index: SPDR S&P500 ETF
  • China: United SSE 50 China ETF

Brokerage Firms

You have to open 2 accounts: 1 with a brokerage firm and one CDP account as explained here.


ETF recommendations 2016:
  • buy Korea/China
  • buy Indonesia
DBS ETF recommendations 2016:
  • Thailand: expect a rebound because of low oil prices.
  • Philippines: strong Peso because of steady stream of remittances coming from foreign workers.

Make Decisions Based on Estimates

My current job involves quantification activities, in particular to estimate the impact of process improvement changes. I have been browsing a book called How to Measure Anything by Douglas Hubbard that brings a whole toolset and methods to go about this.

The main idea in this video is that you can make decisions based on simple calculations rather than relying on human judgement alone. There are at least 3 tools to help with measurement: decomposition, confidence intervals, and Monte-Carlo simulation.

From SOX to Scrum: We've Come a Long Way...

If you're a hard-nosed developer you might not like the methods brought in 'from above'. You might think that scrum for instance is just another annoying management fad that is being imposed to you by ugly trolls.

Well stop mumbling like an old lady because it could be much worse. You don't really know what pain is until you've been through compliance changes such as Sarbanes-Oxley where any handoff between teams becomes an opportunity for setting up a quality gate and multi-layered document sign-offs. Customers are made guilty for requesting changes, developers are made guilty from any deviation from the plan...

Out of all methods/standards I was exposed to over over the years I prefer the agile family where the feedback of users facing a working product is the main driver for everything else. And agile is focused on making that feedback happen as often as possible. Check out this video shot between Tokyo and Singapore:
