It's been crazy lately, more than 90% of the tickets have fallen every day, and from January to now, 14 of the 21 trading days have been green.
The CNI 2000 Index is this month, GEM refers to **, Science and Technology 50**
Alas, anyway, I'm too lazy to complain, A shares are not angry, and it is useless to scold.
I can only look at the U.S. stocks, and now it's all up to them to take flight.
Recently, there was a ** I'm quite concerned about,Dow Jones Industrial Average ETF (513400),It will be listed on the A-share market in the near future.
This ** tracks is:Dow Jones Industrial Index, is an old cannon with a history of 140 years, and it will also give you a simple science popularization.
First of all, the rules of preparation of Jones Industries are extremely simpleIt selects a representative** from each sector (except for transport and utilities) and then selects 30 votes to be included in the index.
These 30 votes, their share-weighted performance, make up the Dow Jones Industrial Average.
I found this index construction rule to be really interesting.
1. First of all, it will not chase up and down, will not take over because of how good the first ticket rises, because it only selects the leader of the subdivided industry.
2. Secondly, the industry distribution is also quite balanced, medicine, consumption, science and technology, finance, all walks of life are leading, basically full coverage.
3. The weight distribution of ** is very special, and the index is weighted according to the stock price. The current index is market capitalization-weighted, and the Dow Jones is based on the stock price, in fact, this is not very scientific, after all, if the stock price is small, the stock price can be very high.
But why has the ** weighting method been used, it is also in 1884 when the information was not developed, and it was convenient to calculate the index, so it was used.
For example,The constituents of Dow Jones Industrial look like this:
Among them, the stock price of United Health is the highest, more than twice as expensive as Apple, which is also its unreasonableness, and later the modern index has changed its rules.
So who wins and who loses when Dow Jones Industrial vs. S&P 500?
In the nearly 34 years since 1990, the difference between the two increases can be said to be a millimeter, Dow Jones**times, S&P 500**14.2 times
However, in the short term, the Dow Jones' earnings are not as good as those of the S&P 500, which has been around for the past five years, and Dow Jones**
The volatility and retracement of the S&P 500 are significantly higher than those of the Dow Jones
The reason why this is the case is simple.
First, the Dow Jones is ** weighted, and the relationship with market capitalization is limited
The S&P 500 is market capitalization-weighted, and the strong are always strong.
In recent years, FAMAG has risen and everyone understands.
Second, the Dow Jones index only selects industry leaders, and some tech giants are not selected.
For example, Apple and Microsoft have entered, resulting in the absence of Amazon and Google.
But the fact is that the more fmaga in recent years, the better, so the Dow Jones has naturally underperformed the S&P 500 in recent years.
But the reincarnation of heaven, who can say for sure in the future?
If the internet continues to YYDS, the S&P may be stronger, and the Dow Jones may be better in turn.
To sum up, I thinkThe Dow Jones Industrial ETF is a diversified, low-risk, low-volatility version of the S&P 500 ETF.
Those who do not have a special preference for Internet technology and prefer a more balanced type can also be used as an alternative to the S&P 500 ETF.
But I personally still think that in terms of the rationality of the preparationThe S&P 500 may be superior to the S&P 500, which combines the advantages of the former with improved weighting rules.
In terms of yesterday's operation, there is no yet, waiting for the next time to return to 9 into a signal....
The bull 20 and the three-legged retracement have been a bit big lately, I'm really sorry,The one-sided A-share is so ** much more than I expected, but now this position, it is really not suitable to cut meat, and when you come to A shares, you still have to follow the customs of the locals, and bear it, everyone.
1. Today's Treasury bond interest rate** to 246%, a 22-year low, while the 30-year Treasury ETF (511090) soared 096%，The main thing is to hedge with A-shares, the worse the economy, the better I am....
2. A large number of companies have released performance outlooks, and the annual profit of Battery Mao Ningde is expected to increase by 38% to 48%.Slightly higher than the consensus expectation of the institution, see if you can bring the GEM tomorrowPig Mao Muyuan is expected to lose 40+ billionushered in the first loss of the year, and the pig price downward cycle expanded against the wind, and finally played itself badly.
3. Musk's brain-computer interface company completed the first case of implantation of chips in the brain of human patientsIt is said that he has recovered well after surgery, and he claims to be able to control the computer with his initial mind, I am thinking about whether a person can still be called a human if the brain computer is connected to ChatGPT in the future? At present, the implanted chip is said to be the size of 5 coins, and with the subsequent volume decreasing, everyone can become IQ200+ in seconds with a minimally invasive operation
