Swine Flu Update

Cliff Notes for “Swine flu: One Killer virus, three key questions.”

swine flu virusBy Ilene

Brendan Maher and Declan Butler, authors of a recently published Nature article “Swine flu: One killer virus, three key questions,” set out to answer three questions about the H1N1 virus. Here’s what they found. 

How does it kill?

Sherif Zaki, head of the infectious-disease pathology branch at the Centers for Disease Control, discusses his team’s observations from their pathological studies.    

1.  The H1N1 virus penetrates deep into the alveoli (the terminal air sacs in the lungs). In contrast, the seasonal flu viruses tend to infect cells higher in the upper airways. This deep penetration is reminiscent of the action of the H5N1 avian flu virus. Zaki commented: “[H1N1] is like avian flu on steroids.”  Why might this be?

Zaki says that his observations fit well with recent research looking at the mechanism of infection. A group led by Mikhail Matrosovich at Philipps University Marburg in Germany and Ten Feizi at Imperial College London studied sialyl glycans, glycoproteins that the flu virus binds to in order to gain entry to human cells. Although seasonal strains of H1N1 bind mostly to versions of the glycoproteins known as α2-6, the researchers found that the new pandemic H1N1 can also bind to a version called α2-3, which is found in greater proportion in the lower respiratory tract.

2.  In patients who have died, co-infection was common with H1N1.  Zaki’s group observed infection with bacteria such as Staph aureus or Streptococcus pneumoniae in about a third of the fatal swine-flu cases. However, in the remaining two thirds of fatal cases, the virus was lethal alone.  The damage seen in the lungs is characterized as ‘diffuse alveolar damage,’ reflecting a very difficult to treat state of respiratory distress syndrome. According to Zaki’s research, about 90% of the fatal cases had some underlying medical condition.

Zaki expects the number of flu cases to increase as the flu season “ramps up.”

How does H1N1 spread?

Brendan Maher visited Peter Palese’s laboratory at Mount Sinai School of Medicine where testing for how the viruses spread is being carried out. Researchers John Steel and Anice Lowen compared the transmissibility of H1N1 to that of seasonal flu using a guinea pig model. Their data indicate that the H1N1 virus transmits as efficiently as seasonal flu viruses, which is consistent with real-world data showing…

Bank Index Breakout? Stock Market Bulls Sure Hope So

Courtesy of Chris Kimble

One of the most important sectors of the stock market is the banking industry and bank stocks.

When the banks are healthy, the economy is likely doing well. And when bank stocks are participating in a market rally, then it bodes well for the broader stock market.

In today’s chart, we look at the Bank Index (BKX).

As you can see, the banks have been in a falling channel for the past 20 months. As well, the banks have been lagging the broader market during this time as well – see the Ratio in the bottom half of the chart above.

Recent rotation in multiple foreign currencies hints at the fact that a new stage of the “Capital Shift” process is taking place and that skilled technical investors need to pay very close attention to how these currencies continue to react over the next 3 to 6+ months.  In the recent past, most of the world’s foreign currencies were declining in value while the US Dollar continued to strengthen.  In fact, we authored many research articles about these trends and how weakness in foreign currencies will drive new foreign investment into the US stock markets for two simple reasons; strength and security. 

Now that a few of the world’s most ...

Review of Andrew CardWell RSI with Wyckoff price waves

RSI measures relative strength of price action of a set period versus prior set periods. It helps review the price swings or waves, the power of each price thrust into new ground, or lack of it. Price thrust like many things relies on energy, and energy is not a constant, it has a birth, a life and a death and relative strength helps us see that cycle.

Look Out Bears! Fed New QE Now Up to $165 Billion

Courtesy of Lee Adler

I have been warning for months that the Fed would need new QE to counter the impact of massive waves of Treasury supply. I thought that that would come later, rather than sooner. Sorry folks, wrong about that. The NY Fed announced another round of new TOMO (Temporary Open Market Operations) today.

In addition to the $75 billion in overnight repos that the Fed issued and has been rolling over since Tuesday, next week the Fed will issue another $90 billion. They’ll come in the form of three $30 billion, 14 day repos to be offered next week.

That brings the new Fed QE to a total of $165 billion. Even in the worst days of the financial crisis, I can’t remember the Fed ballooning its balance sheet by $165 bi...

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...
