The clearest evidence of a retreat from physical gold can be seen in the holdings of the world’s largest gold-backed exchange traded fund, SPDR Gold Trust, down more than 20 tonnes to about 1,111 tonnes since December 29. “As long as risk aversion is low investors will prefer equities to the metal because physical gold is a synonym for fear,” said Eugen Weinberg, commodities analyst at Commerzbank. The stampede to gold is likely to resume later this year, when tighter monetary and fiscal policy to rein in potential inflation and government deficits respectively reinforce fears of financial, political and economic instability.īut for now, many investors expecting a more benign environment than they have seen in the last couple of years and wanting to keep their exposure to gold have shifted their money from the physical to bullion producers. currency continues its ascent and makes the precious metal more expensive for holders of other currencies. Gold’s popularity will return because investors fear inflation and sovereign downgrades, even if the U.S. Of calling spline_filter on the original input.A man carries a bowl of gold at SJC gold factory in Ho Chi Minh city January 22, 2010.

Way such that the last point and initial point exactly overlap. Red shift is a key concept for astronomers. The input is extended by wrapping around to the opposite edge, but in a The input is extended by wrapping around to the opposite edge. ‘grid-wrap’ ( a b c d | a b c d | a b c d) This mode is also sometimes referred to as whole-sample The input is extended by reflecting about the center of the last The input is extended by replicating the last pixel. Occurs for samples outside the input’s extent as well. The same constant value, defined by the cval parameter. ‘grid-constant’ ( k k k k | a b c d | k k k k) Interpolation is performed beyond the edges of the input. The input is extended by filling all values beyond the edge with ‘constant’ ( k k k k | a b c d | k k k k) This mode is also sometimes referred to as half-sample The input is extended by reflecting about the edge of the last Value is as follows (see additional plots and details onīoundary modes): ‘reflect’ ( d c b a | a b c d | d c b a) The mode parameter determines how the input array is extendedīeyond its boundaries. The order of the spline interpolation, default is 3.

The two axes that define the plane of rotation.
