give it your best effort to be objective, instead of being offensive.
Yepper do! As so many cos. announced buybacks of shares (which may not ever happen, nor are they obligated to fulfill,) one does need have a look around and ask themselves: "Self, where are the potential buyers of shares/investors?"
That old saw about how a co. views their common stock as undervalued, and announces a buyback is usually pretty much propaganda, and market media fluff.
As expected, no replies was my answer. Why would anyone buy a home they have to pack a lunch to visit, with a shower#$%$/shine, and wash/rinse/repeat to go to a job to pay for it?
Not according to their very own guidelines, and parameters. As I have previously stated, no fed has asked me for my employment status, nor that of my two (2) sibs who are also unemployed, and not not on any UI or public assistance programs.
It the polltakers are missing me and 2 of my 4 sibs, what else have they overlooked?
The is no blood in a turnip. Greece has the upper hand by being the stepsister who owes, and big time.
Give 'em all you want, they don't have a robust economy, and there is not a foreseeable way to pay back the staggering debts they have encumbered.
OK. I've been unemployed since 2008 or prior. I've never collected a penny of UI monies, and am ineligible to do so for years. Not one person from any gov agency has polled the 2 of my other sibs who are also unemployed, and not on UI, nor myself. I'd call their results a bit skewed, wouldn't you?
And when a man isn't working, he's usually devastated. We gals who are unemployed take any downturn a bit more in stride; at the end of the day, if I'm not covering my expenses, zero of my money goes into your pocket. Especially here in SoCal. I'd like to see a line item report as to which employers are paying wages which employees can afford to puchase homes within a reasonable (45 minutes, with traffic,) commute.

As if beating lowered estimated earnings is considered a plus? That game has been played too often, and at least a 15% correction is necessary to clear out the bar room, and sweep the floors. A 30% drop would be a buying opportunity.
I'm a registered Republican, and Elizabeth Warren is our next President. Some of her thoughts I like. Her political party is opposed to mine, but she's a well rounded woman, and I admire a few things I've seen in her public view.
DAQWYAKTA. And yes, I may chose to purchase some shares of oil and and gas stock that may have slippled during this rerun. I'm not SEC, and they already know about me, because I have highlighted their less than stellar attention to many items in the financial markets.

Ternary plot of different colors of Ag-Au-Cu alloys
Pure gold is slightly reddish yellow in color, but colored gold in various other colors can be produced.
Colored golds can be classified to three groups:
Alloys with silver and copper in various proportions, producing white, yellow, green and red golds; typically malleable alloys
Intermetallic compounds, producing blue and purple golds, as well as other colors. These are typically brittle but can be used as gems and inlays
Surface treatments such as oxide layers
Pure 100% gold is 24 karat by definition, so all colored golds are less than this, with the common being 18K (75%), 14K (58%), and 9K (38%).

White gold is an alloy of gold and at least one white metal, usually nickel, manganese or palladium. Like yellow gold, the purity of white gold is given in karats.
White gold's properties vary depending on the metals and proportions used. As a result, white gold alloys can be used for many different purposes; while a nickel alloy is hard and strong and therefore good for rings and pins, gold-palladium alloys are soft, pliable and good for white gold gemstone settings, sometimes with other metals like copper, silver, and platinum for weight and durability, although this often requires specialized goldsmiths. The term white gold is used very loosely in the industry to describe karat gold alloys with a whitish hue. It is a common misconception that the color of the rhodium plating, which is seen on many commercial pieces, is actually the color of white gold. The term "white" covers a large spectrum of colors that borders or overlaps pale yellow, tinted brown, and even very pale rose. The jewelry industry often conceals these off-white colors by rhodium plating.
A common white gold formulation consists of 90 wt.% gold and 10 wt.% nickel. Copper can be added to increase malleability.
The strength of gold-nickel-copper alloys is caused by formation of two phases, a gold-rich Au-Cu, and a nickel-rich Ni-Cu, and the resulting hardening of the material.
The alloys used in jewelry industry are gold-palladium-silver and gold-nickel-copper-zinc. Palladium and nickel act as primary bleaching agents for gold; zinc acts as a secondary bleaching agent to attenuate the color of copper.
The nickel used in some white gold alloys can cause an allergic reaction when worn over long periods (also notably on some wrist-watch casings). This reaction, typically a minor skin rash, occurs in about one out of eight people and because of this, many countries do not use nickel in their white gold formulations.
Rose, red, and pink gold
"Red gold" redirects here. For the deciduous Australian Red Cedar tree, see Toona ciliata. For other uses, see Red gold (disambiguation).
Rose gold is a gold and copper alloy widely used for specialized jewelry. Rose gold, also known as pink gold and red gold, was popular in Russia at the beginning of the nineteenth century, and was also known as Russian gold although this term is now obsolete. Rose gold jewelry is becoming more popular in the 21st century and is commonly used for wedding rings, bracelets, and other jewelry.
Although the names are often used interchangeably, the difference between red, rose, and pink gold is the copper content: the higher the copper content, the stronger the red coloration. Pink gold uses the least copper, followed by rose gold, with red gold having the highest copper content. Examples of the common alloys for 18K rose gold, 18K red gold, and 18K pink gold:
18K Red gold: 75% gold, 25% copper
18K Rose gold: 75% gold, 22.25% copper, 2.75% silver
18K Pink gold: 75% gold, 20% copper, 5% silver
12K Red gold: 50% gold and 50% copper.
Up to 15% zinc can be added to copper-rich alloys to change their color to reddish yellow or dark yellow.
During ancient times, due to impurities in the smelting process, gold frequently turned a reddish color. This is why many Greco-Roman texts, and even many texts from the Middle Ages, describe gold as "red".
See also: Crown gold
The highest karat version of rose gold is also known as crown gold, which is 22 karat. Eighteen karat red gold may be made of 25% copper and 75% gold. For 18 karat rose gold, typically about 4% silver is added to 75% gold and 21% copper to give a rose color. 14 karat red gold is often found in the Middle East and contains 41.67% copper.
High-end flutes are very commonly made of solid rose gold, the most common alloy being 14K.
Some gold copper-aluminium alloys form a fine surface texture at heat treatment, yielding an interesting spangling effect. At cooling, they undergo a quasi-martensitic transformation from body-centered cubic to body-centered tetragonal phase; the transformation does not depend on the cooling rate. A polished object is heated in hot oil to 150 - 200°C for 10 minutes then cooled below 20°C, forming a sparkly surface covered with tiny facets.
The alloy of 76% gold, 19% copper, and 5% aluminium yields a yellow color; the alloy of 76% gold, 18% copper and 6% aluminium is pink.
Further information: Electrum
Green gold was known to Lydians as long ago as 860 BC under the name electrum, a naturally-occurring alloy of silver and gold. It actually appears as greenish-yellow rather than green. Fired enamels adhere better to these alloys.
Cadmium can also be added to gold alloys but there are health concerns regarding its use. The alloy of 75% gold, 23% copper, and 2% cadmium yields light-green 18-karat gold. The alloy of 75% gold, 15% silver, 6% copper, and 4% cadmium yields a dark-green alloy,
Grey gold alloys are usually made from gold and palladium. A cheaper alternative which does not use palladium is made by adding silver, manganese and copper in specific ratios to the gold.
All the AuX2 intermetallics have crystal structure of CaF2 and therefore are brittle. Deviation from the stoichiometry results in loss of color. Slightly nonstoichiometric compositions are however used, to achieve a fine-grained two- or three-phase microstructure with reduced brittleness. A small amount of palladium, copper or silver can be added to achieve a less brittle microstructure.
The intermetallic compounds tend to have poor corrosion resistance. The less noble elements are leached to the environment, and a gold-rich surface layer is formed. Direct contact of blue and purple gold elements with skin should be avoided as exposure to sweat may result in metal leaching and discoloration of the metal surface.
Gold-aluminium phase diagram
Purple gold (also called amethyst gold and violet gold) is an alloy of gold and aluminium rich in gold-aluminium intermetallic (AuAl2). Gold content in AuAl2 is around 79% and can therefore be referred to as 18 karat gold. Purple gold is more brittle than other gold alloys, (a serious fault when it forms in electronics), as it is an intermetallic compound instead of a malleable alloy, and a sharp blow may cause it to shatter. It is therefore usually machined and faceted to be used as a "gem" in conventional jewelry rather than by itself. At a lower content of gold, the material is composed of the intermetallic and an aluminium-rich solid solution phase. At a higher content of gold, the gold-richer intermetallic AuAl forms; the purple color is preserved to about 15% of aluminium. At 88% of gold the material is composed of AuAl and changes color. (The actual composition of AuAl2 is closer to Al11Au6 as the sublattice is incompletely occupied.)
Blue gold is an alloy of gold and indium. It contains 46% gold (about 12 karat) and 54% indium, forming an intermetallic compound AuIn2. While several sources remark this intermetallic to have "a clear blue color", in fact the effect is slight: AuIn2 has CIE LAB color coordinates of 79, -3.7, -4.2 which appears roughly as a greyish color. With gallium, gold forms an intermetallic AuGa2 (58.5% Au, 14ct) which has slighter bluish hue. The melting point of AuIn2 is 541 °C, for AuGa2 it is 492 °C. AuIn2 is less brittle than AuGa2, which itself is less brittle than AuAl2.
A surface plating of blue gold on karat gold or sterling silver can be achieved by a gold plating of the surface, followed by indium plating, with layer thickness matching the 1:2 atomic ratio. A heat treatment then causes interdiffusion of the metals and formation of the required intermetallic compound.
For the colloquial term black gold, see crude oil.
Black gold is a type of gold used in jewelry. Black-colored gold can be produced by various methods:
Electroplating, using black rhodium or ruthenium. Solutions that contain ruthenium give a slightly harder black coating than those that contain rhodium.
Patination by applying sulfur- and oxygen-containing compounds.
Plasma-assisted chemical vapor deposition process involving amorphous carbon
Controlled oxidation of gold containing chromium or cobalt (e.g. 75% gold, 25% cobalt).
A range of colors from brown to black can be achieved on copper-rich alloys by treatment with potassium sulfide.
Cobalt-containing alloys, e.g. 75% gold with 25% cobalt, form a black oxide layer with heat treatment at 700 - 950 °C. Copper, iron and titanium can be also used for such effect. Gold-cobalt-chromium alloy (75% gold, 15% cobalt, 10% chromium) yields a surface oxide that's olive-tinted because of the chromium(III) oxide content, is about five times thinner than Au-Co and has significantly better wear resistance. The gold-cobalt alloy consists of gold-rich (about 94% Au) and cobalt-rich (about 90% Co) phases; the cobalt-rich phase grains are capable of oxide-layer formation on their surface.
More recently, black gold can be formed by creating nanostructures on the surface. A femtosecond laser pulse deforms the surface of the metal, creating an immensely increased surface area which absorbs virtually all the light that falls on it, thus rendering it deep black, but this method is used in high technology applications rather than for appearance in jewelry.
Oxide layers can also be used to obtain blue gold from and an alloy of 75% gold, 24.4% iron, and 0.6% nickel; the layer forms on heat treatment in air between 450–600 °C.
A rich sapphire blue colored gold of 20-23K can also be obtained by alloying with ruthenium, rhodium and three other elements and heat-treating at 1800 °C, to form the 3–6 micrometers thick colored surface oxide layer.
