The total of net gain (loss), prior service cost (credit), and transition assets (obligations), as well as minimum pension liability if still remaining, included in accumulated other comprehensive income associated with a defined benefit pension or other postretirement plan(s) because they have yet to be recognized as components of net periodic benefit cost. | Matrix.

Accumulated change in equity from transactions and other events and circumstances from non-owner sources, net of tax effect, at period end. Excludes Net Income (Loss), and accumulated changes in equity from transactions resulting from investments by owners and distributions to owners. Includes foreign currency translation items, certain pension adjustments, unrealized gains and losses on certain investments in debt and equity securities, other than temporary impairment (OTTI) losses related to factors other than credit losses on available-for-sale and held-to-maturity debt securities that an entity does not intend to sell and it is not more likely than not that the entity will be required to sell before recovery of the amortized cost basis, as well as changes in the fair value of derivatives related to the effective portion of a designated cash flow hedge. | Matrix.

Uh, today I leave the company. Um they let me go.I have nothing to say. It's the good time,it's the bad time. Sometimes something you don't want,But when they lose you feel sad. Maybe the people Who I worked with. I didn't have new colleagues for a long time. I also feel sorry for them. I could be a good colleague and a good employee for the company. But I can't fit in the team and can't do well with the manager. I always think I'm the manager. I struggle to fit in the group. I'm not comfortable with this type of job. I'm not cut out for this job. This job doesn't suit me. I remain appreciate them.

Below are again the average value and turnover plots for the vec_avg field. Average value hovers densely around 15,000 and turnover around 130%. Here as well, you need to reduce turnover by using ts_rank or ts_decay in your Alpha expression.

下面是vec_avg字段的平均值和周转图。平均价值在15000左右,成交率在130%左右。在这里,您也需要在Alpha表达式中使用ts_rank或ts_decay来减少周转率。
Well-performing Alphas often have economic significance, and combining multiple Alphas can create synergies. This approach can help build more robust Alphas.
Try using Alphas in Trade_when's entry and exit conditions. With Alphas A1 and A2, you can write formulas like:
>> worldquantbrain_2
>> worldquantbrain_2
We've learned about the basic ideas of creating Alpha. The BRAIN platform ensures you create new ideas different from previously submitted Alphas through a self-correlation check process. However, you don't necessarily have to create just one Alpha from a single idea. You can expand your idea to create and submit multiple viable Alphas using the following methods.
Moreover, if you can create multiple viable Alphas from one idea, this might indicate that it's a robust idea that works well under various constraints. However, be careful not to overfit by fine-tuning too many details to increase In-Sample performance, as this could lead to poor Out-Sample performance.

我们已经了解了创建Alpha的基本思想。BRAIN平台确保您通过自相关性检查过程创建不同于之前提交的Alphas的新想法。然而,你不一定必须从一个想法中创建一个Alpha。您可以使用以下方法扩展您的想法,以创建和提交多个可行的阿尔法。此外,如果你能从一个想法中创建多个可行的阿尔法,这可能表明这是一个在各种约束下都能很好地工作的强大想法。但是,请注意不要通过微调太多细节来提高In-Sample性能,因为这可能会导致Out-Sample性能不佳。
Apply time series operators with a suitable period to reduce noise in this daily data. ts_sum or ts_mean work well for this purpose.
Rank the data and set a threshold. For example, to classify half the stocks as True and the rest as False, use a condition like rank(X) > 0.5.
>> worldquantbrain_2
>> worldquantbrain_2
使用具有适当周期的时间序列运算符来减少日常数据中的噪声。ts_sum或ts_mean很好地用于此目的。对数据进行排序并设置阈值。例如,要将一半的股票分类为True,其余的分类为False,请使用rank(X)>0.5这样的条件。
The second input of group_neutralize(x,group) allows you to input group data. Group data fields are data that classify each instrument based on specific criteria. You can use various data fields, including sector, industry, and subindustry, which can be found in the settings, as well as additional datafields like exchange. You can find many group datafields in Price Volume Data for Equity and Relationship Data for Equity, so take a look for useful datafields that suit your needs.
>> worldquantbrain_2
>> worldquantbrain_2
group_nneutralize(x,group)的第二个输入允许您输入组数据。组数据字段是根据特定标准对每个仪器进行分类的数据。您可以使用各种数据字段,包括部门、行业和子行业,这些字段可以在设置中找到,以及交换等其他数据字段。您可以在股票的价格-数量数据和股票的关系数据中找到许多组数据字段,因此请查找适合您需求的有用数据字段。
Your Alphas might be a good Alpha that works quite well even in smaller universes. Since different universes often lead to lower correlations, this can increase diversity in terms of Alpha submission.
Check the Alpha's performance by simulating across various universes.

你的阿尔法可能是一个很好的阿尔法,即使在较小的宇宙中也能很好地工作。由于不同的宇宙往往导致较低的相关性,这可以增加阿尔法提交的多样性。通过模拟不同宇宙来检查Alpha的性能。
Earlier in the submission criteria, we saw the Subuniverse Test, which checks if Alpha signals persist in smaller universes. By verifying if the Alpha works well in universes with higher liquidity where signals are harder to generate, it assesses Alpha's robustness.
If an Alpha fails this test, it likely works from low-volume stocks, making it difficult to realize in practice. In such cases, Subuniverse Sharpe can improve by concentrating positions more on high-volume, large-cap stocks.

在提交标准的早期,我们看到了亚宇宙测试,它检查阿尔法信号是否在较小的宇宙中持续存在。通过验证Alpha在流动性更高、信号更难产生的宇宙中是否工作良好,它评估了Alpha的稳健性。如果阿尔法未能通过这一测试,它可能会从低容量库存中工作,这使得在实践中难以实现。在这种情况下,Subuniverse Sharpe可以通过将头寸更多地集中在高容量、大盘股上来改善。
Momentum -Assume that stocks which have performed well in the past will continue to perform well, while stocks that have performed poorly will continue to do so.
Momentum effect typically appears over longer periods (several months or more).

动量-假设过去表现良好的股票将继续表现良好,而表现不佳的股票将持续表现良好。动量效应通常出现在更长的时间内(几个月或更长时间)。
