It is the number one curse in the A-share market. Since the listing of PetroChina at the end of 2007, as long as this ticket rises sharply, other stocks, especially various theme stocks, will definitely plummet. So that PetroChina has become the most effective bearish signal for A shares.

Data Verification: Since the listing of PetroChina, except for the first day of listing, * * * has increased by more than 5% for 28 times. In these 28 trading days, the index performance only fell twice on the same day, and there were 13 times the next day. For the impact of individual stocks, only 8 times out of 28 times, more than 50% of the stocks fell on the same day, and 12 times, more than 50% of the stocks fell the next day.

Conclusion: The rise of oil in the data does not constitute the standard of "negative curse" for both indexes and individual stocks. On the contrary, when PetroChina rose, the market performance on the same day and the next day was quite good.

2, steel curse

Description of the curse: As long as the steel plate leads the market, the market will be bearish that day.

Data verification: According to the Shenwan first-class industry index, since 2007, steel plates have increased by more than 3%, ranking first in all industries for 40 times. There were only four drops that day, and 2 1 time the next day. There were six times when the share of stocks fell by more than half, and there were 18 times when the share of stocks fell by more than half.

Conclusion: It seems that neither the index nor individual stocks can achieve the so-called spell effect on the same day or the next day.

3. Investment strategy will curse.

This is a very nonsense spell. In recent years, as long as China Merchants Securities held an investment research strategy meeting, the stock market was bearish that day. This kind of thing seems meaningless, but the data is very convincing.

Data validation: it is calculated from the end of 20 1 1, and it is divided into two days at the middle and the end of each year, with a *** 16 trading day until the middle of 20 15 years. Among them, the market fell on the day of 12 trading days, and the stocks that rose on the day of1/kloc-0 trading days accounted for less than 50%.

Conclusion: When the strategy meets, the probability of the market falling exceeds 70%, and the spell is basically fulfilled.

4. Black Thursday Curse

However, in the past two years, the probability of the market falling on Thursday is extremely high, and the market is generally bearish on Thursday.

Data verification: As this spell only rose in recent years, it only takes Thursday from 20 14, and * * * has 84 trading days. Among them, the market fell 44 times, accounting for about 52%; Individual stocks fell 47 times, accounting for more than 50%, accounting for about 56%. When the sample is changed to 20 15, the above indicators are 46% and 5 1% respectively.

Conclusion: the probability of falling is only about 50%, which can't meet the standard of spelling.

5, refers to the delivery day spell

Every time the futures index is delivered, the market will be bearish.

Data Verification: Since the establishment of10,2010A stock index futures in April, as of September this year, there are 66 delivery days in * * *. Among them, the market fell 29 times, accounting for 44%; Individual stocks fell by 3 1 time, accounting for over 50% and 47%.

Conclusion: Maybe it was, but it is definitely not now.

6. The curse of 6.IPO

During the intensive issuance of new shares, the market is often bearish that day.

Data verification: After 2007, there were 568 trading days in which new shares were issued, and 32 trading days in which the amount of funds raised exceeded 654.38+000 billion, which was a high-risk trading day for new shares. The data shows that there are only 8 trading days when the market falls, accounting for less than 30%; But on 16 trading days, more than half of the stocks fell, just 50%.

Conclusion: Although the funds may be negative, the negative impact on the market does not seem obvious.
