Watch list of possible upcoming news which will unsettle the market

To be ready for action of trading, I have made a watch list for the possible upcoming news which may unsettle the market,

1.  S&P credit rating: Concerns over the size of United States debt reared their head once again as ratings agency Standard & Poor’s warned that health care costs for a number of highly-rated Group of 20 countries, including the U.S., could hurt growth prospects and harm their sovereign creditworthiness from the middle of this decade.

Here is the link http://www.cnbc.com/id/46202656. However, I am not sure about the exact date, I will keep searching for it.

2.  Greece’s debt

Time is running short. A deal on restructuring Greece’s debt is needed by mid-February if Athens is to avoid missing a 14.5 billion euro debt repayment in mid-March, which will force a default.

3. Also Greece’s debt

Mr. Venizelos (Greece’s PM) said the aim was to conclude talks with the so-called troika of foreign lenders — the European Union, the E.C.B. and the I.M.F. — by the end of the week so that the framework of a new economic program for Greece was in place before a possible meeting of euro zone finance ministers next Monday.

Officials hope the agreement on the second Greek bailout will be followed in March by a decision to construct a bigger firewall for the euro zone at the same time that a permanent €500 billion rescue fund is established. Both steps are seen as crucial for the restoration of market confidence in the single currency.

4. Facebook IPO

Valued at $100bn, Facebook expected to hold record-breaking IPO launch in third week of May.

I have reserved some cash in my 401k and stock portfolio, once the market dipped unrationally, I plan to buy more shares. However, if Euro woe greatly spreads out and there is no solution in sight, I might sell some to be ready to buy more in the future.
