The adoption of artificial intelligence has increased exponentially in the past few years, with many companies starting to work with AI to a certain extent. While there have been many in the finance industry that claims to utilize AI as part of everyday business operations, there are clear hurdles that need to be overcome if AI is to be more widely integrated into the industry and play a more productive role within it. Some of the major challenges for the wider adaptation of AI within the finance industry are-
1. Lack of usable financial data
2. The difficulty in AI transparency and explainability (XAI).
Being fully aware of the issues that hinder the adaptation of AI in finance, Qraft Technologies has been able to develop solutions that can fully take advantage of what AI can offer despite the challenges that exist.
It may seem like an oxymoron to suggest that there isn’t enough financial data out there for artificial intelligence to run on. However, this is most definitely the case.
According to the New York Times, the amount of time data scientists spend sorting out bad data, a process they refer to as ‘data wrangling’, amounts to somewhere between 50-80% of their entire time worked. In a shocking study, IBM estimated that bad data cost US-based companies $3.1 trillion in 2016. This is possible as an article in the Harvard Business Review suggests that it costs 10 times more to complete work in which the data is defective or lacking in some form or another. Whether the data input is incomplete due to human error or negligence, the problem is rampant and difficult to address.
The ushering of the new age of data science has also given rise to ‘noisy data’. Noisy data refers to data points that have increased in number in the past decade but must be sorted out due to their poor value. Because so many data points now exist, metrics based on this noise have proliferated as well. Noisy data may occur from the simple fact that in this age of ‘big data, data is created just for data’s sake.
One illustration of the consequences of the lack of usable data can be shown with the difficulties in financial modelling. When creating functions that especially depict non-linear relationships, the main problem that arises is the problem of overfitting or underfitting.
Overfitting refers to the fact that relationships and correlations made with existing data (training data) may not hold when new data points (testing data) are introduced. It suggests low bias (because of its success with training data) but a high variance in results (as it has difficulty with testing data). Underfitting occurs when no verifiable clear relationship can be found with existing data. It signifies high bias and high variance in results.
So, any data cannot just be added to AI, nor can it train with insufficient data. How can we handle this situation? This is the point where financial experts can fill in the gaps. They can make inputs in adjusted forms with financial knowledge and insights to augment insufficient data through imputation, simulation, or any other method that makes sense.
Qraft’s Kirin API is the crucial first step that is used to tackle the issue of poor data. It can cut in time the number of hours spent pre-processing financial data, by ensuring the elimination of various biases that can skew data. It can easily sort data by specific investment universes, giving decision-makers an easy way to filter data on demand. The ability can allow human managers to easily see trends and insights that the data may show when formulating their strategies.
With this support, we can better utilize AI, Machine Learning, and Deep Learning. In other words, AI’s current role in asset management is to be a tool used by asset managers, helping them to realize their intuitive strategy optimally with scalability.
One of the biggest hurdles left for AI to overcome is the classic problem faced by many paradigm-shifting technologies- that of explainability.
This is especially true of developments concerning AI due to its complex nature. In its 2021 Business & Finance Outlook, the OECD highlighted “The explainability conundrum” as one of the major challenges faced for the deployment of AI in finance. It highlights the gap in technical literacy between many of those working in finance in being able to understand and explain to consumers, as well as the gap that exists for regulators and lawmakers that need to create the guidelines to make sure AI is ethically used.
Qraft’s Alpha Factory- composed of the Factor Factory and Strategy Factory can address both the issues of poor data and AI explainability, as it allows human input to fill in the gaps that exist in financial data, as well as give humans a say in portfolio construction. This would allow human managers to have an influence by selecting factors such as but not limited to investment universe, goals, horizon, and features. Human managers will therefore have the final say and thereby enable managers to answer for themselves the reasons as to why they made certain decisions, alleviating some of the concerns of AI explainability and accountability.
A complete black box will not be acceptable to many stakeholders, giving way to the necessity for more transparency. Some argue that the ‘black box’ created by AI is no different from that made by complex high mathematical financial models. This is true to an extent, but different, as some AI models cannot be explained at all. In some jurisdictions (Germany), AI models that are not explainable are prohibited. But this must also be balanced with the need to protect IP and to be mindful of not constraining innovation with explainability restraints.
One solution comes from the OECD, by way of the OECD AI Principles, which in general promotes a more human-centric approach to AI, in which humans remain the final decision maker. Given the early stage of this promising technology, and the various stakeholders involved, it remains to be seen whether a comprehensive framework will be agreed to in the near future. However, some general framework will be needed if AI is to achieve its potential in the financial industry.

Investors should consider the investment objectives, risks, charges and expenses carefully before investing. For a prospectus or summary prospectus with this and other information about the Fund, please call 1-855-973-7880 or visit our website at www.qraftaietf.com. Read the prospectus or summary prospectus carefully before investing.
The Funds are distributed by Foreside Fund Services, LLC
Investing involves risk, including loss of principal. The Funds are subject to numerous risks including but not limited to: Equity Risk, Sector Risk, Large Cap Risk, Management Risk, and Trading Risk. The Funds rely heavily on a proprietary artificial intelligence selection model as well as data and information supplied by third parties that are utilized by such model. To the extent the model does not perform as designed or as intended, the Fund’s strategy may not be successfully implemented and the Funds may lose value. Additionally, the funds are non-diversified, which means that they may invest more of their assets in the securities of a single issuer or a smaller number of issuers than if they were a diversified fund. As a result, each Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. A new or smaller fund's performance may not represent how the fund is expected to or may perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Read the prospectus for additional details regarding risks.
While it is anticipated that the Adviser will purchase and sell securities based on recommendations by the U.S. Large Cap Database, the Adviser has full discretion over investment decisions for the Fund. Therefore, the Adviser has full decisionmaking power not only if it identifies a potential technical issue or error with the U.S. Large Cap Database, but also if it believes that the recommended portfolio does not further the Fund’s investment objective or fails to take into account company events such as corporate actions, mergers and spin-offs.
QRAFT AI-Enhanced U.S. Large Cap ETF: Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of health care through outpatient services.
QRAFT AI-Enhanced U.S. Large Cap Momentum ETF: The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund’s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, the loss of patent, copyright and trademark protections, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market.
QRAFT AI-Enhanced US High Dividend ETF: Securities that pay dividends, as a group, may be out of favor with the market and underperform the overall equity market or stocks of companies that do not pay dividends. In addition, changes in the dividend policies of the companies held by the Fund or the capital resources available for such company’s dividend payments may adversely affect the Fund. In the event a company reduces or eliminates its dividend, the Fund may not only lose the dividend payout but the stock price of the company may also fall.
QRAFT AI-Enhanced U.S. Next Value ETF: The value approach to investing involves the risk that stocks may remain undervalued, undervaluation may become more severe, or perceived undervaluation may actually represent intrinsic value. Value stocks may underperform the overall equity market while the market concentrates on growth stocks. The small- and mid-capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic evens than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of small- and mid-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.
