Kanpur Investment：The survivor of A shares is biased; can A shares be rising without quantification and short tools？Professor Liu is not clever

Source: Snowball APP, author: Hai Zejun, (USAAF) conducted a study of the damaged aircraft returned to the base during World War II. At that time, statistical scientist Abraham Wald was requiredAnalyzing how to increase the survival rate of bomber. In sight, the U.S. military believes that the armor should be strengthened on the places where there is the most bomb marks on the plane, but Wald has proposed a very critical insight.

Wald pointed out that the distribution of bullet marks observed actually represents the part where the aircraft can withstand damage and safely returns.In other words, these bullet marks are not the cause of the crash of the plane.Really fatal injuries occur in areas that have no magazines, because those who have been killed by fatal blows have no chance to return to the base at all, so they cannot be counted.Based on this observation, Wald suggested to strengthen armor in areas with less bullet marks to protect the vulnerability that may cause airplanes to be unable to return.

This theory was later known as the "Survivorship Bias", which describes the phenomenon that only pays attention to the survivors and ignores the sample, which leads to the problem of error conclusions.Wald's opinion not only changed the layout of the airline, but also emphasized the importance of consideration in the data analysis, even if they did not show directly in the data set.Kanpur Investment

Based on this theory; we can see a clear thing; what is the survivor deviation of A shares?

A paragraph of Professor Liu made the A shares roll into a strange circle of demolished; seeing that we have stock index futures, stock index options, conversion fusion;

Now the quantification and high frequency are also allowed to be short.

After canceling the trading loan, did Professor Liu look forward to the incremental funds?

Is the marketing market active?Has the market rising market rising?

Obviously not.

During World War II, several major mistakes in the German Nazis were that there were no strategic air force; there was no strategic bomber.

The United States became the hegemony after World War II, mainly relying on the establishment of a strategic Air Force; strategic bomber.

One night, a million people in the cities of the Tuqi people were scratching the sac.Cancel all the stock index futures and options;

Cancelled the quantification, is it backward?Is it equivalent to making the development right of finance, just like a strategic bomber, so he locks himself?

Lock the development of your own financial market;

What should I do in the next 20 years?Those stupid leeks who are stupid follow the bricks' shouts are all dead; what should I do in the market?

The survivors of A shares are the scholars, including Professor Liu Jipeng, you, you, you have never traded A shares;

You have not operated exchanges, securities companies, fund companies, etc.; In your minds, there is no even a complete framework for the healthy development of the healthy development of the transaction environment.

Why are the modern British financial experts, the chairman of the Federal Reserve and the vice chairman from Wall Street and investment banks?

People have seen fat pig running and eating fat pork.

And where do you guess what the pig looks like, a group of people who paint blindly.

The deviation of A shares is to discover a point; it feels that there are a lot of short tools; the actual overall size is not particularly large.Including the trading business.

It is actually the prototype of stock futures.It's just a bit unfair.

Here, think about it, does the Indian stock market have no stock futures?Is there no stock index futures?Is there no stock index optionKanpur Stock?No right certificate?

Why has the Indian stock market rising?

You should not study deeply, the Indian stock market is also a bulk stock marketHyderabad Investment. Why has it been rising?

Why do we have been falling?

Just throw out a short timeHyderabad Stocks?

It's all canceled, did it rise?

What else to cancel?

If foreigners establish A shares stock futures, stock index futures, stock index options, etc.; Establish more complex financial derivatives; then, is it the biggest loss of our financial power?

The financial market has been occupied by others, our own market.

This is not to say, the key is to cancel, can you rise?

As an expert, there is no basically participation in the market; there is no experience in market operations; there is no even the full process planning of the market; even if the development of the market is not mastered; emotional condemnationIs it?

I have no doubt that Professor Liu's personality.But I suspect your level.

You scoffed at the market T+0 at the time, saying that this was a source of risks to make investors lose money; now I feel that quantitative high -frequency T+0.001 has made money in the market;

The shorter this separation time, is it risk or a chance?

Are you schizophrenia?Or is knowledge lacking?

What experts do you?

One day a day, five people, and six people, the stirring market is smoky;

Watching the US stock market has broken a record high again, breaking 40,000 points; Dow Jones; the stock markets around the world are breaking the new high; India, Japan, etc. are breaking the new high.We rescued the market year after year; our A shares fell for a long time.

What is this?

Ask you again, is the real estate mortgage leverMumbai Stock Exchange?Is the down payment leverage?Is it the option for the property market T+0?Is it lever to reduce real estate loan interest?

Why dare not oppose it?

In fact, we India, there is no economics, and there are no financial experts; Tsinghua University I believe there are some people who can be called a professional scholar;

In fact, these "pseudo -experts" who are fired now can't even talk about professional scholars.

Your understanding of economy and finance is too shallow.

Therefore, A shares have a big decline and turbulence; most of them are given by these people; there is no way.
