Yi Cheng had lunch and had just returned to the hall, ready to find a place to lie down for a while, when a human resources manager called him over and scolded him.

To the effect that investors are the parents of food and clothing, how can they be rough with investors, forget it this time, if you still commit it, you will be expelled immediately, balabala.

His fingers almost poked the tip of Yi Cheng's nose, and Yi Cheng also took a lot of effort to endure not breaking his finger.

In the end, Guo Ling rushed over when he heard the news, so he persuaded the human resources manager to come down.

Guo Lingxian put his arm around Yi Cheng's shoulders, called him aside, and whispered, "This guy is also new here, and he is looking for someone to stand up." You ignore him, it's okay, with me covering, he can't move you. You just don't take it to heart. ”

Yi Cheng reluctantly smiled and said, "Just have your words, captain." ”

"Next time, you should also pay attention, don't be strong," Guo Lingxian passed on his experience, "Something like this, someone is making trouble here, and it is impossible for the leader not to know." The leader didn't speak, how much do you mean by stupidly going up and driving people away?"

"It was Sister Yu, the investment manager, who asked me to go......"

"The investment manager is a fart," Guo Lingxian sneered, "If you want to stay here for a long time, you have to be more mindful, which people's words must be listened to, and you must do it immediately; ”

Yi Cheng replied helplessly: "Got it, thank you captain." ”

It's unpleasant to work for others, so Yi Cheng swears that he will never work for people in his life.

After the afternoon close, nothing happened. Yi Cheng left the post, went to the cubicle where Yu Dongni worked, and greeted with a smile: "Sister Yu, I'm here to learn from you." ”

Yu Dongni raised her head, smiled, and pushed a strand of hair that fell behind her ear, "Xiao Yi, I heard that Manager Zhou criticized you, I'm really sorry for causing you trouble." ”

"It's not your fault, Sister Yu, it's also that I didn't handle it calmly enough," Yi Cheng pretended to self-examine, "By the way, Sister Yu, you said you wanted to teach me stock investment, do you have time now?"

"Wait a minute, I'm done writing this report. ”

Yi Cheng stood in place, looking down at Yu Dongni's full chest curve for a moment, and looked away with difficulty.

This Yu Dongni's appearance can only be said to be delicate, but this pair of behemoths is really the best, and I don't know if it's genuine or cushioned.

After a while, Yu Dongni turned around and smiled: "It's okay." Where do you want to start?"

Yi Cheng thought for a while and said, "I have studied programming, and I am particularly interested in our company's stock market analysis model, and I want to know a little bit about it. "If he can get that model through Yu Dongni, then he won't even have to work the night shift.

It's a pity that Yu Dongni shook her head and said, "I don't know much about that model." I've only heard that it's designed based on chaos theory. ”

Yi Cheng nodded as if he didn't understand. Chaos theory, in the 22nd century of the earth is also famous, applied in many fields, it can even be said that the emergence of super artificial intelligence is also related to chaos theory, Fuxi's core algorithm is partly based on the formula of chaos theory.

Yu Dongni continued: "Understanding the law of stock market volatility is a very challenging and world-class problem. It can be said that until now, there has not been any theory or method that is convincing and can stand the test of time. Our company's analytical model is relatively advanced, but it is impossible to predict 100% accurately, not even 60%. If you can make a stock market analysis model with a prediction accuracy of 60% in the future, it will be enough for you to make hundreds of millions of dollars in the stock market in one year. ”

Yi Cheng nodded. That's exactly what he wanted to do.

Yu Dongni didn't pay attention to Yi Cheng's expression, and said to herself: "A few years ago, when the Royal Swedish Academy of Sciences awarded Robert Schiller the annual Nobel Prize in Economics, it was pointed out that there is almost no way to accurately predict the direction of the stock market and bond market in the next few days or weeks, but it may be possible to predict prices for more than three years through research. Now we can do long-term analysis with a decent accuracy rate, but we can't do short-term analysis. Otherwise, it wouldn't have happened at noon. ”

She shook her head and followed her own train of thought and said: "We now analyze the stock market through three methods: basic analysis, technical analysis, and evolutionary analysis, of which fundamental analysis is mainly used in the selection of investment targets, and technical analysis and evolutionary analysis are mainly used in the time and space judgment of specific investment operations, as a useful supplement to improve the effectiveness and reliability of securities investment analysis." You'd better find an introductory book to read it and learn more about it. ”

Yi Cheng nodded, not listening at all. If it weren't for the need to give Fu Xi a lesson, he wouldn't have bothered to listen to such a boring thing.

After Yu Dongni explained these three analysis methods to Yi Cheng in detail, she called up a few market charts, gave Yi Cheng an introductory lesson, and finally talked about some basic principles of quantitative stock selection through the company valuation method, trend method and capital method.

At the end she asked, "How is it, how much do you understand?"

Yi Cheng smiled and said, "A little bit, I'll go find the book first and read it for myself." To his disappointment, Yu Dongni didn't seem to have access to that stock market analysis model.

"How old are you?" Yu Dongni asked curiously, "I feel like you're still a student." ”

"I just graduated from high school. ”

"You should continue to study, even if you take a self-examination diploma, you will have more room for development in the future," Yu Dongni sighed, "Being a security guard is not a lifelong career." ”

"I think so too," Yi Cheng said with a smile, "If I have the chance, I will continue to study." ”

"If you want to learn investment operations, you can buy a few books to read, and I will write you a book list, and ask me if you don't understand it." Yu Dongni found a pen, tore half a page from the folder, and wrote the names of several books. At the end is a string of numbers, apparently her phone number.

Yi Cheng did not refuse her kindness, although he knew very well that he would probably never read these books in his life. He smiled gratefully: "Thank you, Sister Yu, then I'll come back to you then." ”

With that, he turned and left.

At more than 5 o'clock, before Guo Lingxian got off work, he called Yi Cheng to the monitoring room, and also called a security guard named "Zhang Jianhui", who looked to be around forty years old, this is Yi Cheng's partner on duty tonight.

Guo Lingxian said in a consultative tone: "Jianhui, Xiao Yi is on the night shift for the first time today, you teach him more and take him to get acquainted with it." ”

Zhang Jianhui nodded listlessly: "I know the captain." Anything else?"

Guo Lingxian couldn't do much about such old fritters, and casually told them a few words, so he waved his hand to let them leave.

Yi Cheng and Zhang Jianhui walked out of the security monitoring room side by side, Zhang Jianhui didn't say a word, and he didn't say hello.

Yi Cheng was happy to be relaxed, it was best to go his separate ways tonight, so he could go and explore the computer room.
