In Play ® - Yahoo! Finance - The basics of investing.

Crystallex has been a speculative stock for years... the permit has always been "one month away".

No longer... 

10:39AM Crystallex announces the Director General of the Administrative Office of Permits has denied request for the authorization to affect natural resources (KRY) 1.65 -0.03 : Co announces it has become aware that the Director General of the Administrative Office of Permits at the Ministry of the Environment and Natural Resources of Venezuela has issued a communication to the Corporacion Venezolana de Guayana, the owner of the Las Cristinas concessions, denying a request for the authorization to affect natural resources to carry out exploration activities in the mining area of Las Cristinas in Sifontes, Bolivar State. In issuing the communication, the Director General cites sensitivities surrounding indigenous peoples, the small miners and the environment in the area generally known as the Imataca Forest Reserve, which contains a number of mining projects, which like those of Crystallex, are seeking the required permits to continue their development and exploitation. The communication by the Director General appears to be in conflict with the Las Cristinas EIS approval, Construction Compliance Bond Request and Environmental Tax request issued by the MinAmb (that Crystallex posted and satisfied last summer) and the communication appears to be in opposition to all mineral mining in the Imataca Region. (stock is halted)

Why Things Cost $19.95: Scientific American

People following price in stock investments will appreciate this.

University of Florida marketing professors Chris Janiszewski and Dan Uy suspected that something fundamental might be going on, that some characteristic of the opening bid itself might influence the way the brain thinks about value and shapes bidding behavior. In particular, they wanted to see if the degree of precision of the opening bid might be important to how the brain acts at an auction. Or, to put it in more familiar terms: Are we really fooled when storekeepers price something at $19.95 instead of a round 20 bucks?

Holiday Patterns/FinancialCalendar.Com - Thousands of Holidays, No Vacations

FinancialCalendar.com is the source of worldwide calendar data.

There are similar year-to-year variations in the number of weekends, with the result that the number of working days can also be very variable (see chart below). The different weighing methods produce different numbers (an average of 259.1 days on a population-weighted basis, 251.4 for GNP and 251.6 for stock market capitalization) because many countries with below-average GNP work a six day week.

This gives rise to an interesting economic question: Should GNP be higher in years when there are more working days? Not being economists, we're not qualified to answer that question. However, we can point out that the effect is very significant in some years. For example, in 2032 there will be 0.9% more working days than in 2031 (see chart below).

A great way to justify purchasing a couple of these for your home/work PC for something other than just gaming.
