Summary of Key Points
Recently in the A-share market, numbers such as 88.88 and 66.00, which are pairs or symmetrical, have been regarded by some investors as a “code” indicating that the market has reached its peak. This phenomenon was particularly noticeable on May 21st and July 1st, when several stocks reached these numbers at their highest points, sparking significant discussion. However, the appearance of such paired numbers is mainly due to trading habits (investors prefer auspicious numbers, and higher-priced stocks tend to have prices that are more rounded). These numbers do not represent signals from major players or institutions, nor do they necessarily reflect market trends; they are merely superficial aspects of stock prices and do not determine price movements. Investors should focus on more fundamental factors such as valuation and performance.
What are “Paired Numbers”? What were the two typical cases this year?
“Paired numbers” refer to numerical sequences that appear in stock prices, such as 22.22, 330.00, or 123.55, which are also known as “pair peaks” or “leopard numbers.” Some believe these are signs of a market top. This has happened twice this year:
- First occurrence (May 21st): All four major A-share indices fell by more than 2%, with the semiconductor sector leading the decline. Stocks like Jiangfeng Electronics, Zhongwei Company, and Xinyuan Micro reached prices of 222.22 yuan, 533.33 yuan, and 330.00 yuan respectively, but their prices subsequently declined after reaching these numbers.
- Second occurrence (July 1st): The Shanghai Composite Index closed in the green, but popular sectors such as semiconductors and CPOs experienced corrections, with the Sci-Tech 50 index falling by 2.48%. Stocks like Zhenbao Technology, Haiguang Information, and Changdian Technology reached prices of 800.00 yuan, 377.88 yuan, and 111.11 yuan respectively, and their prices also fell after reaching these paired numbers.
These two incidents have led many to equate “paired numbers” with market peaks, but is that really the case?
Why do Paired Numbers Appear Frequently?
The frequent appearance of paired numbers is mainly due to investors’ trading habits:
- Preference for auspicious numbers: Domestic investors tend to favor numbers like 6 (which sounds positive), 8 (symbolizing prosperity), and 9 (representing longevity). They subconsciously choose prices like 11.11 or 166.88 when placing orders in hopes of good luck.
- Higher-priced stocks are more likely to have paired numbers: For high-priced technology stocks, small changes in price (e.g., 0.01 yuan) have little impact on profits and losses, so investors prefer to place orders at round prices. For a stock priced at 100 yuan, a 0.01 yuan change only affects the price by 0.01%. Setting the price at 88.88 is both convenient and considered auspicious, leading to more occurrences of paired numbers at higher points over time.
In short, these are small habits that collectively make paired numbers more common in the market.
Are Paired Numbers Signals from Major Players?
Claims that numbers like 88 (meaning “bye-bye” or “sell”), 66 (meaning “leave”), and 00 (meaning “reset”) are signals from major players or speculative funds are purely speculative:
- Lack of evidence: Experienced traders argue that these interpretations are subjective assumptions with no factual basis. Trading is the result of negotiations between buyers and sellers; no single person can convey signals through numbers. You might think 88 means selling, but someone could simply have chosen a favorable price.
- Quantitative trading does not use these cues: There were rumors that quantitative trading strategies used to drive down prices based on paired numbers, but a survey by Yicai found that such strategies do not consider these numbers as signals. These claims are unfounded.
In other words, these “codes” are just interpretations created by investors themselves and have no real significance.
Are Paired Numbers Related to Market Trends?
There is no definite connection between paired numbers and market movements. In fact, there are counterexamples:
- Prices continued to rise after paired numbers appeared: On April 29th, the Shanghai Composite Index exceeded 4100 points, and several stocks reached paired numbers (e.g., Mol线程 at 699.99 yuan, Industrial Foxconn at 67.77 yuan), but the index continued to rise, and these stocks also increased in value.
- True reasons for corrections: Experts point out that the declines on May 21st and July 1st were due to excessive sector growth (high valuations and large profit margins). Paired numbers simply coincided with these high points; they were not the cause of the drops. The real determinants of stock prices are valuation, performance, and capital flows.
Therefore, there’s no need to panic when you see paired numbers—they are just a superficial phenomenon and not predictors of market trends.
What Should Ordinary Investors Do?
For individual investors, paired numbers should not be taken seriously:
- **Don’t believe in “codes”: So-called market signals based on numerical patterns lack standardized significance, and trying to trade by guessing these numbers is unreliable.
- Focus on key factors: When buying stocks, consider the company’s fundamentals (performance), industry prospects (potential for growth), and valuation (whether the price is reasonable). These are the real determinants of stock prices.
- Rationally view market fluctuations: Market corrections are normal; don’t rush to buy or sell based on unusual numbers.
In summary, paired numbers are a result of trading habits and should not be treated as signals of market trends. Investing should focus on more tangible factors.
