Affection System: I have everything the goddess wants.

Chen Jie patiently and meticulously broke down the topic content:

"The first part is financial data crawling and cleaning. We need to use a Python interface to continuously crawl basic trading data such as daily charts, intraday charts, trading volume, and turnover rate of A-shares, Hong Kong stocks, and US stocks, while also organizing macroeconomic data, including indicators such as interest rates, exchange rates, CPI, and PMI."

The raw data is disorganized, contains missing and outliers, and requires manual filtering, cleaning, format standardization, and processing to build a complete database.

"The second part is the construction of quantitative factors and financial modeling. Based on classic financial models such as the Capital Asset Pricing Model, Arbitrage Pricing Theory, and Momentum Reversal Strategies, and combined with machine learning algorithms, we build multi-dimensional quantitative factors, covering value factors, growth factors, momentum factors, and volatility factors, to construct a customized quantitative trading model."

"The third part is strategy backtesting and parameter optimization. We put the built model into historical market data of the past ten years for backtesting to verify the strategy's win rate, return rate, maximum drawdown, Sharpe ratio and other core indicators. We continuously adjust parameters, optimize the model, eliminate ineffective strategies, and improve the model's stability in actual combat."

"The fourth part is data statistics and empirical analysis. SPSS, Stata, and Matlab are used to perform significance tests, correlation analyses, and robustness tests on the backtesting results to verify the effectiveness of the model, eliminate random errors, and ensure the authenticity and reliability of the data."

"Finally, there's the writing and compilation of the research findings. This involves outlining the research logic, experimental process, and data conclusions, creating charts and graphs, compiling a literature review, and finally completing the writing and submission of the paper to a core journal."

After explaining the entire research process, Chen Jie looked at Cao Xu gently, his tone patient and tolerant, without any perfunctory or contemptuous tone: "Junior brother, you've just entered the lab, so you don't need to tackle the most difficult modeling and algorithm parts right away. Don't put too much pressure on yourself."

Take a look at these jobs. Which one would you like to try first? I'll guide you step-by-step and teach you slowly.

As soon as he finished speaking, the other three master's students in the office subconsciously stopped what they were doing, looked up at Cao Xu, and waited quietly for his answer, their eyes filled with curiosity.

Chen Jie thought for a moment, then asked softly, "By the way, junior, how's your computer fundamentals? Do you use software like Python and Matlab often?"

Cao Xu remained calm and said indifferently, "It's very average, almost impossible."

Chen Jie was not surprised to hear this, and continued to guide him with a gentle smile: "It's okay, it's normal to have no experience, you'll learn gradually."

Of the three most basic tasks—data processing, model backtesting, and basic statistical analysis—which one interests you most?

Cao Xu remained completely honest, without any pretense: "To be honest, I don't know anything about these areas right now, and I'm not interested in them at all."

The office fell silent for a moment after these words were spoken. The three master's students looked at each other, a hint of surprise flashing in their eyes.

Is this some old man? He's not interested in anything and can't do anything?

A third-year undergraduate student with absolutely no prior knowledge was personally brought into the core laboratory by the vice dean and even had his postgraduate recommendation spot reserved in advance. This treatment is simply outrageous.

Chen Jie was taken aback, then looked troubled. He was always kind and considerate and never liked to make things difficult for his junior brother, let alone put pressure on Cao Xu so soon after he started.

He pondered for a moment, smiled helplessly, and kindly compromised, "How about this, you can't get started with the research work for now, and you don't have to force yourself to learn. If you come to the lab when you're free, you can just help us buy food, pick up packages, and run errands. It's easy and simple, and you don't have to use your brain. It'll also count as you working in the lab."

Upon hearing this, Cao Xu's lips curled up slightly, and he readily agreed: "This is fine, this is the most suitable for me."

Just then, Cheng Yang, a burly fat man standing to the side, could no longer contain his curiosity and couldn't help but ask, his tone filled with direct doubt: "Junior brother, may I ask a question?"

"You're only a junior, you have zero foundation, you don't know any research, you have no interest in anything, and you don't want to learn. How can you expect a professor to personally guide you? And even reserve a spot for graduate school in advance?"

He sized up Cao Xu, who exuded confidence and an impressive aura, and continued to press, "Is it because your grades in your major courses are overwhelmingly the best, or do you have connections at home, like being a second-generation official or a second-generation rich kid?"

Lu Jiahao and Lü Qian nodded in agreement, their eyes fixed on Cao Xu, filled with curiosity—a question shared by all of them.

Cao Xu answered frankly and truthfully, "I'm not a second-generation rich kid at all; my family is just an ordinary one."

"My grades in my major courses during my freshman and sophomore years were average, and I was not quite up to the minimum requirements for graduate school recommendation. My professor asked me to come to the lab to gain some experience in order to prepare for graduate school recommendation."

The teacher was willing to accept me mainly because I trade futures and forex, and have achieved some success in overseas financial markets.

"He probably valued my practical skills in this area. He brought me to the lab to gain some research experience and make up for my shortcomings in getting into graduate school. That's all."

After hearing this, Fatty Cheng Yang suddenly realized what was going on and slapped his thigh: "Oh! I knew your name sounded familiar!"

"That post that's been pinned to the top of the school forum for almost a month—that's you, the third-year student who started from scratch and single-handedly made a fortune in the overseas financial market, achieving instant fame—is that you?"

Cao Xu nodded calmly and modestly: "It's me. My teacher appreciates my talent and is willing to give me a chance to pursue a master's degree. But I'm really not good at academic research or data analysis; I'm just not cut out for it."

"I mainly focus my energy on attending classes and practical trading. I haven't passed the CET-6 (College English Test Band 6) yet, and I have to take the exam next month. I don't think I'll have much time for lab work afterward."

Chen Jie, the easygoing man standing to the side, instantly understood Professor Zhang's intention, smiled and waved his hand, showing remarkable insight:

"I understand. Then you don't need to feel any pressure or come to the lab to work. Come and sit and play when you have time, and when you don't have time, just focus on your classes, prepare for the CET-6 exam, or do your own thing. You don't need to be tied down by lab work."

Cheng Yang was completely impressed, his eyes filled with admiration. He quickly leaned closer and asked, "Junior brother, you're amazing! Can I ask you quietly what stocks you've been holding lately? Do you have any promising prospects? Could you share your knowledge with us?"

Before Cao Xu could respond, Chen Jie immediately stopped him, saying, "Fatty, don't ask questions!"

He solemnly instructed, "How many times have I emphasized the lab rules! We can exchange and discuss trading experiences and market trends, but absolutely no stock recommendations, no order placements, and no private trading advice. These are the bottom lines, and the key to avoiding risk. Why can't you remember?"

Cheng Yang, embarrassed by his senior's scolding, quickly composed himself, scratched his head, and apologized, "Hehe, I forgot, I forgot, it's my fault, I won't ask again next time!"
