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:

- Noteworthy: JP Morgan has revised RBA's cash rate projections to no change all the way through 2012

- Interestingly, Deutsche Bank sees floor under copper price at US$6600/t. Aluminium expected to prove more resilient as global growth slows

- Citi believes copper will find natural floor at US$6400/t. Buying opportunity selected stocks. Rio Tinto preferred, also keen on PanAust

- Barclays says biggest threat to China is global recession which could trigger 1st hard landing (5.5-6.5%) in 2 decades, policy options avail

- Citi revised USD forecasts, anticipates rallies in medium term. AUD expected to stay below USD parity, EUR projected 1.32 to Dec, then 1.27

- Says Dennis Gartman: All Ords likely on its way to 4250-4300, but rally unlikely to be sustained as Europe's problems are far from over

- Interesting comment by Katheen Brooks at Forex.com: EUR/USD needs to surge above 1.3660 or this rally in equities won't be sustainable

- In case of slower growth next year, GS prefers gold and mineral sands among resources equities and avoid exposure to aluminium and nickel

- New trend in global research: recession in Europe. The question thus becomes: what with the rest of the world? Slower growth guaranteed?
