I joined Twitter. Not because I am curious what this celebrity has to say about her kids, or to read that another one is waiting for a connecting flight, impatiently. Twitter allows me to follow news and commentary sources such as Dow Jones' Marketwatch, Bloomberg News and the Wall Street Journal. It assists me in keeping up with what is happening across the globe, while I am observing and analysing financial markets myself.

While I am on Twitter, reading a quote here and a news flash there, I offer my own succinct insights and commentary. Those amongst you who have already discovered the virtues of a Twitter account can add my Tweets to their daily news via @filapek.

For those who have no intention to join Twitter, but would like to stay up to date, below are my Tweets from the week past:
