The cache
Finance could be understood as the science that seeks to optimize resources while minimizing risk. Most of our emotional well as follow this pattern sound without often we realize. For example, when drive trying to find the shortest way to save money and time to evaluate various alternatives, including shortcuts, while we further optimize the route, usually with some sort of added risk (the famous "there is no shortcut unemployed).
In the book "The hidden logic of life" shows us some interesting, not least the book begins by analyzing the incredible increase in oral sex among young Americans. If we analyze "economically" oral sex is a "price" as low-risk pregnancy and contracting diseases is much lower than that of sex, therefore it would be the most appropriate choice for the small economist in all of us ( and that "small economist" is not a metaphor). Thus, what at first seems an immature behavior is much more rational than we think.
In computing, we have other methods to optimize resources, we can spend the dough on a server or we can install a large system cache. This system is what makes leaving memorized most frequently visited pages, so that when a user accesses the web, rather than having to load and access to the database page shows memorized. It is as if you work on your faq email address and opt, instead of reciting, have tattooed on your hand and save you spell your email.
As mentioned before, many times the resource optimization entails risks, this is what we did with the cache and some of our readers have been almost a week without seeing the site updated.
That was also what happened to banks in the famous subprime mortgage crisis, using a system of "packaging" mortgage (a shortcut to get better performance), but taking too many risks. Is the highest in finance and life, more risk than return, do not give you more turns.
In Cotizalia we read an opinion piece entitled: And the bomb exploded financially. When the search for profitability ignores risk (II). That is to summarize the current crisis on 3 points:
- Fatten the cow until bursting
- The speck in the eye of others and the beam in the
- Peep, peep that I have not been
In Spain it seems that this will not remain with us and to our world of fantasy and color and read with amazement the next release as Invertia "coupled to rapid credit: Spaniards pay more (9.25%) than Europeans consume" .
Consumer credit are two hundred basis points more expensive in Spain than elsewhere in Europe. The national average stands at 9.25% versus 7.21% applied to the forward transactions between 1 and 5 years in the Eurozone. Spain to invest more in the payment card and the recruitment of direct credit, a loan that is not based only on assets and guarantees to support a higher risk premium.
If at the end we will have what we deserve. Like it's because we know a lot of economy, not the poor that Warren Buffet recently said "Is it the economy? I have no idea "
Warren Buffett says that he has no idea of where the economy goes. And because you are not interested, he says, this is not your business. Are words that clash, coming of which is the richest man on the planet, and especially someone who has gained the nickname the Oracle of Omaha.
Of course, that what is involved is not to the economy if not to finance, which is certainly a guru. Meanwhile, other "gurus" are dedicated to predicting $ 200 oil, which go to whether you will or not but the truth is that it gives some fear.
In fine, friends, be very careful with the cache.

Os dejos this theater, which explains the subprime mortgage market and those who are
Presenter: George Parros, you are an agent of investments
George Parros: I am, yes.
Presenter: And as you have checked the "pulse" of the financial market.
George Parros: Yes, one could say so.
Presenter: And last summer there were a lot of turbulence .... ... Volatility.
George Parros: If tremendous
Presenter: And what is the cause?
George Parros: Well we must remember two things about the market: The first is that it consists of very sharp and sophisticated people. Heads are the big world. And the second is that financial markets are driven by feelings.
Presenter: What does that mean?
George Parros: What does that mean? Well, things are going normally, and suddenly, without more, of these sophisticated people saying, My God! What will happen? Oh We've lost everything! What will we do? Ah ... .... ¿Salto for sale? Jumped out the window. Everyone. SOLD! , SOLD!
Presenter: Yes.
George Parros: Precisely ... and then one of those sophisticated people saying, "You know, I think everything is going well." And they all say, "I agree. We are rich, are rich "
Presenter: "Buy, Buy, Buy"
George Parros: Buy, buy, buying, yeah. And to call that "market sentiment".
Host: Yes .... Surely we are exaggerating a bit.
George Parros: Ah, well I do not know in August last year, when markets plunged in London is a well known firm issued a statement said, and I'm quoting, market players do not know whether to buy in rumor and sell on the news, do the opposite, no two, as the wind direction.
Presenter: Yes, and this is the kind of rigorous analyzes the salaries that these companies are huge.
George Parros: And some days later when the situation improves, a senior ABM said and I quote, back to happy days again
Presenter: No money to buy that kind of mature wisdom.
George Parros: Probably not. These people receive millions in bonuses.
Presenter: There have been actual causes behind the volatility of the market. Especially in the U.S. for many mortgages made to people who can not pay for properties that are losing value
George Parros: Where are the subprime mortgages.
Presenter: Subprime, if .... How does that?
George Parros: Imagine, if you are able to sit in a black unemployed demolished a porch, with a sleeveless T-shirt somewhere in Alabama. And a guy comes and asks Do you want to buy this house before it falls? We provide the money.
Host: And this guy is a banker.
George Parros: No, no. It is a seller of mortgages. Your salary depends on how many venda. So your assessment is very objectionable.
Presenter: Yes, yes, absolutely. And then what happens?
George Parros: Well, a bank buys the debt, the mortgage and other debts with similar packaging
Presenter: Without going into detail about ....
George Parros: No, no ... It's too boring ... so that is packaged and then goes to Wall Street. And something extraordinary happens. Somehow these packages risky debts, ceases to be and becomes a structured vehicle debt.
Presenter: A SIV
George Parros: If a SIV.
Presenter: OK, and then someone like you goes and buys it.
George Parros: Yes, and then call someone in Tokyo and I say, "Look, I got this package You want to buy? I wonder what's in it?. I would not have the slightest idea. I wonder how much I ask, I say $ 100 million. I said okay, and that's all. That is the market.
Presenter: And presumably happen several times with the same package. And if someone like you will make money with it.
George Parros: Do not expect to do anything. It is hard work ....
Presenter: On which these packages are very debt arriegasdas Why attract investors?
George Parros: Because these funds are very good free names.
Host: You mean companies that are respectable?
George Parros: No, no. Nothing to do with his reputation. You have very good names. They are very creative. For example, there is a well known firm, Bear Sterns, who has two such funds. They lost so much money they announced that they would get $ 3.2 million to keep one foot. Yet investors lost money
