God-level Trader of Rebirth

Chapter 398 Quantitative Feasibility

"This whole set will cost tens of millions, right?" A young man asked, pointing to the slowly rotating disc on the record player.

"Not counting the acoustic decoration, a small light bulb on the top of the head costs tens of thousands of yuan. On the left and right sides, none of the full set of speakers can't afford 2000 million yuan, and the cables at the back are probably not cheap. More than 1000 million yuan is still needed."

"No way? Just these wires cost more than 1000 million? Isn't that more profitable than chips?"

"Of course, if the cable is compared to a road, then the signal is a car. The road condition is good, and the car can go smoothly. Therefore, the cable is the key to the "last mile" sprint of the sound."

The other person obviously had some research on the sound configuration, helped his glasses on the bridge of his nose, and explained in a low voice.

"Good guy, it's not so expensive to sing with Zhou Huimin in your arms."

The young man gasped.

"Huh?! Ah Wei, Ah Ju, why are you here?"

Chen Jie was leaning on the sofa, half asleep and half awake, vaguely heard soft voices, opened his eyes suddenly, and saw Chen Weidong and Lin Zeju pointing at some equipment.

"Hey, I said why you haven't come to the company recently, so it turns out that you are secretly engaging in corruption here."

Chen Weidong walked around the office twice, tired from standing, so he sat down on the sofa and said jokingly.

He and Lin Zeju had just returned from a meeting at the municipal center, passing by Yuehai Street, so they stopped by to have a look.

The first floor of the building is the trading hall, which is quite lively. Many stockholders gather to discuss market conditions. Research reports, etc., are more suitable for high-frequency trading.

The upper floor is the office area for the core personnel of Infinity Securities and public funds.

Both entities are in the same building.

Chen Jie pressed a crystal button on the sofa, called the secretary to make some cups of coffee through the pager, and then put on a sincere attitude, talking endlessly: "Awei, you don't understand this, right? You should have some hobbies, don’t be busy with work all day long, you can’t make enough money, you should enjoy more while you are young.”

"And let me tell you, in the financial circle, I'm definitely very restrained. Now, whoever has a little wealth, who doesn't raise ten or eight lovers outside, every day."

"Okay, okay, don't go into such details about this kind of thing, it's indecent. We're here this time, just to see how your side is doing."

Chen Weidong hurriedly asked him to stop the car, and changed the topic to public funds.

"It's okay. I have bought most of the funds raised in the market into real estate stocks. What do you think?"

Chen Jie was suddenly interrupted, and he seemed a little unfinished, but when he talked about the market, he became interested again.

"There is no big problem, just strictly implement your trading plan, based on the continuous entry of off-market incremental funds, as long as you have patience, profit is a high probability event." Chen Weidong thought for a while, and the bull market has already started No, there is no good suggestion.

Judging from his previous experience as a top trader in the industry.

The biggest difference between institutions and those bookmakers and private equity is the decision-making method and mechanism.

To put it simply, an institution doesn’t need to care about whether its own strategy has driven retail investors away, whether it needs to be cleaned up, or whether it will be attacked by the market. It only needs to gradually implement the customized plan.

why?

Because the amount of funds of the organization is large enough, it is playing elephant dance, and it has absolute crushing strength. There is no need to worry about someone sneering behind the scenes, and there is no saying that funds are trapped.

In addition to self-operated trading, they have countless channels to obtain funds, and then cover their positions, and they can quickly unwind.

What can affect them are all real big market trends.

But that was only a temporary drag.

"Well, I feel relieved with your words. By the way, last time I heard from Lao Lu that the company's research department is working on a system of heaven, which can use powerful computing power and artificial intelligence to simulate various the result of an experiment."

"This system is so powerful, can it be used to predict the medium and long-term trend of the market, or to conduct transactions?"

The mixed fund that Chen Jie is in charge of now has a very high rate of return, and the scale has exceeded 1000 billion very early, and it is still increasing. Such a huge amount of funds is not small for any institution to fully operate. difficulty.

As for the original core personnel of Infinity Private Equity, as they enter the late middle age, their brains are not as fast as before, and many people have begun to retire one after another. Although the traders who joined later, although their quality is also good, they still lack the experience of large capital operations. .

This is very embarrassing.

The allocation and utilization of funds are directly related to whether the rate of return can be maximized.

If there is a tool to assist this process, it should be much easier.

"Are you talking about quantitative investment? I remember that in the past two years, some domestic institutions seem to have launched a quantitative fund. How is the effect?" Chen Weidong took a sip of coffee to refresh himself, his brain was running fast, and he was thinking about the feasibility of this matter .

"Don't mention it, the quantitative fund of Hwabao Trust is ridiculous. It has been launched for a year and has lost more than 20 points. It is better to find someone to manage it."

Chen Jie scoffed at this.

After he served as a fund manager, he also took time to understand over-quantitative investment.

The development of quantitative investment originated in overseas markets. From a global perspective, the development of quantitative investment in overseas markets has a history of at least 50 years, and it gradually emerged in the 60s and 80s.

Hwabao Trust adopts the same data-driven approach as abroad to carry out investment transactions, and wants to predict the trend and shape of stocks through the data itself and strict statistics.

This sounds, it seems very scientific.

But in fact, quantitative investment is very easy to fall into the trap of historical data.

The logic of quantitative investment is to use historical data to find statistical laws. This is inevitable, and data overfitting will occur, resulting in a strategy that is clearly profitable during the simulation, but is not ideal when put into the real market. situation.

Because history does not simply repeat itself.

As for why quantitative investment has been so successful in the United States, it is because the Dow Jones Industrial Index has been in a "slow bull" market all year round. As long as the model customization strategy is not too bad, it can achieve good returns.

From [-] to [-], the four-year volatility of the American stock market, it is not difficult to see that the performance of quantitative investment is actually very average.

The A-share market has always been volatile, and there is no long-term trend to speak of.

In terms of individual stocks, there is no logic, and they like to follow the trend and speculate blindly. After the hot money of the dealers retreats, it is even more flimsy, and it will take a long time to adjust to recover.

This kind of market, quantitative investment, is obviously not suitable.

But his intuition told him that the "Tiandao System" developed by the company must not be a simple artificial intelligence, otherwise there would be no need to make such a big move, and the computer department alone could handle it.

"Well, I will ask the project team to deploy a few people to help you design a system that matches the stock market, but its specific trading logic still requires you to find some traders and analysts to continuously supplement and improve, so that you can Improve accuracy."

Chen Weidong considered for a moment, finally nodded, and agreed to the matter.

After all, he also wanted to see whether the thinking model based on the theory of the Book of Changes would have unexpected effects when applied to the stock market.
