"Xuedi Li, look, this is our problem. There is a lot of data here."
Zhang Weilong found the part in the document that described the problem, then greeted Li Mu and introduced him.
"Then here are our mathematical models of nine of the leading trading strategies most commonly seen in the market today."
"And our purpose is to find the relationship between the three characteristics I told you before among these nine trading strategies, so as to determine the risk issues."
He pointed to the three characteristics mentioned earlier.
"We need to start with UMVE portfolio theory, which is unbiased minimum variance estimation, and then..."
"Look, if you have any questions, just ask me directly."
Quickly, Zhang Weilong briefly described the problem, and then looked at Li Mu.
Li Mu nodded and stood in front of the multimedia projection screen and looked at it for a few times. In the end, maybe he felt that it was too tired to stand and watch, so he said, "Send it to me directly and I will watch it on my own computer."
He always kept his computer in his bag. He was originally going to take it to the library, but Yun Rongshang called him over as soon as he arrived at the library door, so he happened to have the computer with him.
He found a seat, then took out his large notebook from his schoolbag and placed it next to the other high-end thin and light notebooks.
When you press the power button, the fan will start whirring. Of course, this is what happens when the phone is turned on. After a while, the fan will quiet down.
Yun Rongshang next to her didn't expect that Li Mu was actually carrying such a big laptop, so she couldn't help but ask: "Don't you think it's heavy?"
"Ah? Are you okay?" Li Mu shook his head.
But it's strange to say that he used to feel that this notebook was very heavy, but now he doesn't feel it anymore.
This seems to be the result of the brain computer?
The brain computer seems to be able to control all the bioelectric currents in his body, improving his IQ and improving his physical condition at the same time.
Without thinking too much, Yun Rongshang turned on the phone and sent all the information to him.
Next, he looked at the problem quietly.
When the people around him saw that he had entered a state of thinking, they stopped talking. 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 serious thinking state, still looks very convincing.
Yun Rongshang, who was next to her, also looked at Li Mu, thinking in her heart that this guy had often underestimated her problems before.
It’s okay now. Is it difficult for you?
But in the end she shook her head in frustration.
What is she thinking!
According to the current situation, it is obviously best for Li Mu to solve this problem as soon as possible.
After all, she had just stood up for Li Mu.
"So, come on, junior! If you have solved this problem, then I will admit that my problems are very simple in your eyes!"
She began to cheer up Li Mu in her heart.
Time passed quickly, probably more than ten minutes passed.
Suddenly, there was a knock on the door of the discussion room. A man went out to open the door, and then a boy walked in.
The people present quickly recognized him. Isn't this the doctoral student from the School of Mathematics that they called over before?
Why is he here again?
Zhang Weilong walked up because this doctoral student in mathematics was his friend and he was the one who called him here in the first place.
"Xu Canyao, why did you come here and didn't you tell me?"
Xu Canyao waved his hand and said, "I don't want to give you a surprise. I have some ideas about your question."
"Really?" Zhang Weilong's eyes suddenly lit up. Of course, others around him also lit up when they heard this.
There is actually a method. You are worthy of being a doctoral student in the School of Mathematics!
At this time, they immediately forgot about Li Mu who was still thinking about a solution next to them.
Of course, this is human nature. When they have been stumped by this problem for many days, anyone who says they have a solution will make them grab a life-saving straw and forget about everything else.
Probably only Yun Rongshang was still paying attention to Li Mu at this time.
Xu Canyao smiled and said: "Of course, can I still lie to you? I even asked my instructor specifically."
"Your supervisor? That Professor Lin Yao?" Zhang Weilong immediately felt more reassured: "It seems that it is stable now. Speaking of which, my supervisor has also collaborated with Professor Lin Yao on papers before, and he has always said that Professor Lin Yao's mathematics is better than ordinary people.
All math professors have to be strong.”
"That is."
When someone praised his boss, Xu Canyao naturally wanted to agree. At this time, he looked around the discussion room and asked, "Are you still thinking about that question just now?"
"Yeah, no, we invited another junior student who is good at mathematics to help. He is even a junior student from the School of Physics."
As he spoke, Zhang Weilong pointed to Li Mu over there who was still thinking.
"Good guys, you've even called those who study physics here? Are you just throwing yourself into a panic... I'm so stupid!"
Halfway through his words, Xu Canyao's eyes widened and he looked directly at Li Mu.
"Uh...what did you say?"
Zhang Weilong was confused. Why did he suddenly say a foul language in the middle of talking?
"No, you told me earlier that you knew this person, why are you calling me?" Xu Canyao pointed at Li Mu, and then said to Zhang Weilong angrily.
Zhang Weilong was at a loss, and so were everyone else around him.
"This? Li Mu?"
"yes."
"What's wrong with Senior Brother Li?"
Hearing the word "Junior", Xu Canyao put on a speechless expression.
"You really dare to call me junior. Let me tell you, none of the graduate students under my boss dare to call him junior now."
"Ah this..."
Zhang Weilong and the people around him looked at each other, "Do you still know him?"
"Of course."
"But he studied physics... Didn't you just want to say that he sought medical treatment because of a sudden illness..."
"Except this one, except this one." Xu Canyao waved his hands repeatedly, "He was also invited to the research team by our Professor Lin. You don't know how awesome this guy is..."
As he spoke, he told Li Mu's deeds in the research group.
Yes, this Xu Canyao is also in Professor Lin Yao's research group.
He had always remembered the fact that Li Mu had easily solved the difficult problems in the project before.
After listening to Xu Canyao's explanation, these graduate students from 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 if they called themselves junior students again, they would be a little unworthy...
Xu Canyao just said that this junior student is even going to publish his second area paper!
Thinking of this, they all felt incredible in their hearts.
How dare they question such a big boss just now?
As for Yun Rongshang, her face was even more surprised.
She often saw Li Mu studying in the library until the library was closed. Coupled with the books Li Mu read, she knew that he was very powerful, but she didn't expect that he was so powerful!
She looked at Li Mu who was still thinking carefully, and couldn't help but said: "Junior, junior, how smart are you?"
So at this moment, Li Mu raised his head, looked at them, and said, "I have a method here."
