"Senior Brother Li, you see, this is our problem, there is a lot of data here."

Zhang Weilong found the part of the document that described the problem, and then greeted Li Mu and introduced him.

"Then here are the mathematical models of the nine leading trading strategies that are most common in our current market."

"And our goal is to find the relationship between the three characteristics that you mentioned earlier in these nine trading strategies, so as to identify the problem of risk."

He pointed to the three characteristics mentioned earlier.

"We need to start with the UMVE portfolio theory, which is an unbiased minimum variance estimate, and then ......"

"Look, if you have any questions, just ask me."

Quickly, Zhang Weilong briefly described the problem, and then looked at Li Mu.

Li Mu nodded, stood in front of the multimedia projection screen and looked at it a few times, and finally felt that it was too tiring to stand and watch, so he said: "Send it to me directly, I will use my own computer to watch it." ”

His computer has always been in his bag, and he was supposed to take it to the library, but as soon as he arrived at the door of the library, he was called by Yun Rongsheng, so the computer happened to be with him.

He found a seat, then pulled his large notebook out of his bag and placed it next to the other people's high-end thin and light books.

Press the power button, and the fan whirring, of course, this is the case when the machine is turned on, and after a while, the fan quiets down.

Yun Rongshang next to him didn't expect Li Mu to be carrying such a big notebook, so he couldn't help asking, "Don't you think it's heavy?" ”

"Huh? It's okay. Li Mu shook his head.

But it's strange to say, in the past, he would think that this notebook was very heavy, but now he doesn't feel it.

It seems that this is also the work of the computer in the mind?

The mind computer seems to be able to improve his IQ and his physical condition at the same time by controlling all the biocurrents in his body.

Without thinking too much, he turned on the phone, and then Yun Rongshang sent him all the information.

Next, he quietly looked at the problem.

When the people around him saw that he had entered a state of thinking, they didn't speak anymore, even if they really wanted to discuss something, they would lower their voices to avoid affecting Li Mu.

In any case, Li Mu, who has entered a state of serious thinking, still looks very convincing.

Yun Rongsheng next to him also looked at Li Mu, and thought in his heart, this guy often underestimated her problems before.

Okay, stumped you, right?

Only in the end she shook her head in frustration.

What was she thinking!

According to the current situation, it is obvious that it is best for Li Mu to solve this problem quickly.

After all, she stood up for Li Mu just now.

"So, come on, junior! If you make this question, then I will admit that my question is very simple in your eyes! ”

She began to cheer Li Mu up in her heart.

Time passed quickly, probably more than ten minutes.

Suddenly, there was a knock at the door of the discussion room, and a man went out to open the door, followed by a boy walking in.

The people present quickly recognized it, wasn't this the doctoral student they had called before?

Why is he here again?

Zhang Weilong walked up, because the doctoral student in mathematics was his friend, and he also called him in the first place.

"Xu Canyao, why are you here, don't tell me?"

Xu Canyao waved his hand and said, "Isn't this trying to surprise you, I have a little idea about your question." ”

"Really?" Zhang Weilong's eyes suddenly lit up, and of course, the other people around him were also dazzled when they heard this.

There is actually a way, and I really deserve to be a doctoral student in the School of Mathematics!

At this time, they suddenly forgot about Li Mu, who was still thinking about the solution next to them.

Of course, this is also human nature, when they have been stumped by this problem for many days, and anyone who says that they have a way will make them forget about it like grasping at a life-saving straw.

Probably at this time, only Yun Rongshang was still paying attention to Li Mu.

Xu Canyao smiled and said, "Of course, can I still lie to you?" I also asked my mentor about it. ”

"Your mentor? That Professor Lin Yao? Zhang Weilong suddenly became more relieved: "It seems that this is stable, speaking of which, my supervisor has also collaborated with Professor Lin Yao on papers before, and has always said that Professor Lin Yao's mathematics is stronger than that of ordinary mathematics professors." ”

"That's it."

Someone praised his boss, of course Xu Canyao wanted to agree, and at this time he looked around the discussion room again, and asked, "Were you still thinking about that question just now?" ”

"Yes, no, we have hired another student who is good at mathematics to help, and even a student from the School of Physics."

As he spoke, Zhang Weilong pointed to Li Mu, who was still thinking about it.

"Good guys, you guys have even called you to study physics? Are you in a hurry...... I grass! ”

Halfway through his words, Xu Canyao's eyes widened, and he looked directly at Li Mu.

"Uh...... What's wrong with you? ”

Zhang Weilong was confused, why did he suddenly burst out of a foul language in the middle of talking?

"No, you said you knew this guy, why did you call me?" Xu Canyao pointed at Li Mu, and then said to Zhang Weilong angrily.

Zhang Weilong was at a loss, and the others around him were also at a loss.

"This? Li Mu? ”

"yes."

"What's wrong with Senior Brother Li?"

Hearing this "junior brother", Xu Canyao put on a speechless expression.

"You really dare to call someone else's junior brother, let me tell you, no one under my boss's graduate student dares to call him junior brother now."

"Ah......h

Zhang Weilong and the people around him all glanced at each other, "Do you still know him?" ”

"Of course."

"But he studied physics...... Didn't you just want to say that this was a rush to the doctor......"

"Except for this one, except for that." Xu Canyao waved his hand again and again, "He was also invited by our Professor Lin to the research group, you don't know how awesome this ...... is."

As he spoke, he told Li Mu's deeds in the research group.

That's right, this Xu Canyao is also in Professor Lin Yao's research group.

And Li Mu easily solved the difficult problems in the subject before, but he has always remembered it vividly.

After listening to Xu Canyao's explanation, these graduate students of the Department of Finance all showed shocked expressions on their faces, and then looked at Li Mu.

This junior...... Bah!

After listening to what Xu Canyao said, they suddenly felt that they were a little unworthy to call their junior brother again......

Xu Canyao said just now, this junior is even going to send a second district paper!

Thinking of this, their hearts all felt incredible.

They actually dared to question such a big guy just now?

As for Yun Rongshang, his face was even more surprised.

She often saw Li Mu studying until it was closed in the library, and with the books Li Mu read, she knew that he was very powerful, but she didn't expect it to be so powerful!

She looked at Li Mu's still thinking carefully, and couldn't help but say, "Senior brother, junior brother, how smart are you?" ”

So at this time, Li Mu raised his head, looked at them, and said, "I have a way here." ”
