I just realized that today is a pretty important day for the market — the CPI index is about to be announced tonight, and according to predictions, it might fluctuate between 25,000 and 50,000. Anything can happen, so I want to share a little about what CPI is so everyone can better understand why this number is so important.

First, what is CPI? It stands for Consumer Price Index — a measure used by the government to assess the health of the country's economy. If you've never paid attention to it, you might be surprised to learn that this number has a significant impact on the stock market and even our wallets.

CPI basically measures the change in prices of everyday products and services that people use. It’s a way to track inflation — in other words, it tells us whether our money is losing value or not. When CPI rises, macroeconomic decisions also change, such as whether the central bank should adjust interest rates.

Now, what does it mean when CPI increases? When CPI goes up, it means the prices of consumer goods are rising. For example, if CPI increases by 2.3% over the past year, your cost of living has increased by an average of 2.3%. This might not seem too bad, but it also means your money is worth less — today, 100 yuan can only buy what 97.75 yuan could a year ago. Purchasing power decreases, and people's real income also declines.

Conversely, when CPI decreases, the prices of consumer goods fall, and purchasing power increases. But this isn’t necessarily good news. Excessive price drops can negatively impact producers, reducing their profits, weakening production incentives, decreasing supply, and ultimately increasing unemployment rates. In the short term, consumers benefit, but if it lasts too long, it can lead to an economic recession.

So, what is CPI for the stock market? The relationship isn’t direct, but it’s very real. In theory, there’s no mathematical link between CPI and stock prices, but in practice, CPI influences the market through financial supply and demand factors. When CPI continues to rise, it triggers structural adjustments in the stock market. Investors need to be cautious about asset price risks. And usually, when CPI keeps increasing, capital shifts toward higher-yield investment markets.

In summary, today’s CPI index will decide many things. I recommend everyone closely monitor this data because it not only affects macroeconomic conditions but also individual investment decisions. Let’s see what the results will be.
