Three days later, Ye Fang went through the discharge procedures for the old lady. Then he packed up his room for Xu Guizhi to live in, and moved into Wang Kai's room. Wang Kai happened to come back from a mission, so he and Ye Fang borrowed the police station's car to move the old lady's belongings from the public housing into Ye Fang's courtyard.

"Grandma, this should be the last thing in the car." Ye Fang and Wang Kai moved all the things in the car into the room. Then Wang Kai went back because he had a temporary task in the bureau. Ye Fang and Xu were the only ones left in the courtyard. The old lady is alone.

After Ye Fang helped Mrs. Xu put everything away, Mrs. Xu took out a box and called Ye Fang to her. Ye Fang didn't know why, so he sat next to the old lady and slowly opened the box. He saw that there was an ICBC passbook inside, as well as some notebooks and yellowed papers. They all looked old.

"Grandma, what are you..." Ye Fang asked.

Mrs. Xu took out a yellowed diary from the box, then closed the box and said slowly, "This contains all my property. There are about 5 yuan in the passbook, and the password is six six... "

"Grandma, I don't want your money." Ye Fang said quickly.

"I know, this is not for you now. If something happens to me in the future, I can't let go of this money. At least first aid to the hospital and funeral expenses all cost money. I think this money should be enough. Yes, I will tell you in advance to let you know, just in case." Mrs. Xu then handed the yellowed notebook to Ye Fang's hand and said, "This notebook is the account book I have kept over the years, and what is recorded in it Maybe it will work for you."

"Well. Don't you like stock trading? There is some information I memorized in it. Let's see if you can understand something from it. If you can see some patterns, it proves that you are still good at finance. If anything If you can't tell, just return this notebook to me and concentrate on running this small supermarket from now on." As she said this, Mrs. Xu handed the yellowed notebook to Ye Fang, who took it and flipped through it. After a few pages, I found that they all recorded the number of tea eggs bought and sold by the old lady.

"Let's go back and watch tonight." Mrs. Xu said gently.

"Okay, I'm going to cook now, and I'll watch it after dinner." Ye Fang said and turned around and went out.

After dinner, there were no customers in the supermarket at this time, so Ye Fang returned to the desk in his room and opened the yellowed notebook.

The written records in the notebook first started in 1992. They recorded the number of tea eggs sold every day, and sometimes also recorded the weather conditions. The records are very detailed, even recording the quantity, location and price of the purchases. In this book, you can clearly see the rise and fall of egg prices over the years.

But since 1993, in addition to recording the daily sales of tea eggs, there are also the rise and fall of the index and some stock information. It may be gossip, and some even have a few words about national policies. Ye Fang guessed that this should be The old lady heard it mentioned by stock investors when she was selling tea eggs.

Starting in 1995, Ye Fang discovered that the old lady's records gradually formed a fixed format, recording the number of tea eggs sold every day, the opening and closing points of the daily market, the prices of some popular stocks, and some current events that have an impact on the stock market. News, all these habits continued until the old lady fell ill.

Ye Fang carefully read through the data recorded in his notebook several times. He always felt that there were some patterns hidden in it, but he couldn't explain it himself. The recorded information seemed to be scattered information, and even this information could be found in many newspapers and stock analysis magazines, but when combined with the tea eggs, Ye Fang felt that there seemed to be some connection.

For several days, Ye Fang stayed in the room and concentrated on reading the information on his notebook. At the supermarket, Mrs. Xu became a saleswoman. Every day, Mrs. Xu would prepare meals and bring them to Ye Fang. Ye Fang sold paper in the room, and even made icons of the tea eggs sold by the old lady in the past five years, and compared them with the stock market performance in the past five years. Ye Fang just sat in front of these data. With.

A week later, Ye Fang finally walked out of the room and rushed to Mrs. Xu's room and shouted, "Grandma, I can see the relationship between tea eggs and the stock market."

"Oh, what did you see?" Old Mrs. Xu put down what she was doing and prepared to listen carefully to Ye Fang's findings.

"I found that the period when tea eggs are sold less every day is often the low point of the market, which means that fewer people enter securities companies every day, which is also a downturn in the stock market. And when tea eggs are sold well, , the market is often active and when the stock market is strong, it means that more people walk into securities companies every day and transactions are more active." Ye Fang said loudly.

"Is there anything else?" Mrs. Xu continued to ask.

"When the stock market is at its lowest point, you may not be able to sell a single tea egg in a day. But when the stock market is at its highest point, you can even sell ten times the number of tea eggs in a day." Ye Fang continued to answer.

"Is there anything else?" Mrs. Xu continued to ask.

"What else?!" Ye Fang recalled carefully and continued, "In the past few years, three times in the past few years, tea eggs were sold more than ten times when the stock market was at its highest point, but after that point, the number of tea eggs sold every day The number of tea eggs quickly decreased."

"Have you ever thought about why?" Mrs. Xu asked.

"That's because the stock index fell sharply soon after the high point. Everyone left the market without cutting their flesh. No one was in the mood to eat tea eggs anymore." Ye Fang replied thoughtfully.

After hearing Ye Fang's words, Mrs. Xu nodded and said, "It's not in vain, so I'll give you that notebook."

Then Mrs. Xu continued to ask, "When do you think you should buy stocks and when should you sell stocks?"

"Of course, buy when the market goes up...buy when the market goes up, sell when it reaches a high..." At the end of the sentence, Ye Fang became less and less confident. Everyone knows that buying at the low point of the stock market is at least the second low. , and then sell at the high point of the stock market, but who can accurately predict the high point of the stock market? If anyone could predict it accurately, how could there be so many locked-up investors?

Suddenly, an idea flashed in Ye Fang's mind, and he blurted out, "Buy stocks when no one is buying tea eggs, and sell stocks when everyone is buying tea eggs! Isn't that so, grandma?"

"That's right!" Mrs. Xu said with a smile, very satisfied with Ye Fang's answer.

"Grandma, did you sum up this with tea eggs one by one?" Ye Fang asked curiously.

Mrs. Xu smiled and said nothing, and asked, "What do you think is being speculated in stocks? Is it performance? Is it a trend? Is it inside information?" The old lady shook her head and continued, "None of them!"

"Grandma, what is that?" Ye Fang asked solemnly.

"People's hearts!" Mrs. Xu Guizhi slowly spit out two words.
