id=\"Introduction\"><\/span>Introduction<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In the world of finance, understanding the sources of investment information is critical for investors and creditors. Reliable data is key to making sound financial decisions and assessing risks. The landscape of investment information is broad, encompassing various sources with differing levels of quality and trustworthiness. Recognizing and evaluating these sources is vital for forming effective investment strategies.<\/p>\n\n\n\n<p>The journey into investment theories has evolved significantly, from foundational concepts like Markowitz&#8217;s Portfolio Theory to advanced models such as Sharpe\u2019s Capital Asset Pricing Model (CAPM). These developments have highlighted the role of stock characteristics in predicting returns and have been instrumental in the emergence of quantitative investment analysis. This field stands at the forefront of financial analysis, with investment data at its core.<\/p>\n\n\n\n<p>This guide aims to demystify the process of identifying and utilizing primary sources of investment information. We&#8217;ll explore how to determine the quality of this information and address common biases in investment data. A practical example could be how a single piece of high-quality, timely information can alter an investor&#8217;s decision, impacting their portfolio&#8217;s performance. Statistics or real-life instances will be used to underline the significance of reliable sources.<\/p>\n\n\n\n<p>Understanding that the sources of investment information vary in credibility, we smoothly transition to how TEJ assists in navigating this complexity. TEJ&#8217;s unique methodology and expertise in data curation and analysis simplify the decision-making process for investors and creditors. By the end of this article, you will have a clearer perspective on assessing and applying investment information to your financial strategies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Primary_Sources_of_Investment_Information\"><\/span>Primary Sources of Investment Information<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Investors and creditors can obtain crucial investment information from various primary sources, including financial markets, company financial data, and corporate events.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Financial_markets\"><\/span>Financial markets<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Financial markets trade assets like stocks, bonds, and options. They provide up-to-date information on prices and transactions. This data reflects what&#8217;s happening in the market, including demand, supply, and future predictions. Most financial markets have an official website where they post this data.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Company_reports\"><\/span>Company reports<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>These are documents a company releases, like financial statements, annual and quarterly reports, and press releases. They give detailed information about a company\u2019s financial status, how it&#8217;s performing, its goals, and any risks it faces. This helps investors and creditors understand where the company stands and its potential for growth.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Corporate_event_data\"><\/span>Corporate event data<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>This data includes information on big events in a company, like changes in management, insider stock transactions, mergers and acquisitions, and changes in policies about dividends and stock. These events are important, and the data usually comes with the dates they&#8217;re announced. This is useful for analyzing how these events affect the company or for more detailed study.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Evaluating_Investment_Information_Sources\"><\/span>Evaluating Investment Information Sources<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>When making investment decisions, investors and creditors need reliable, relevant, and timely sources of investment information. However, with numerous information sources available, how to verify the source of investment information that is high quality for investors and creditors to make decisions concerning a company?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reliability\"><\/span>Reliability&nbsp;<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The reliability of an information source is based on its accuracy, completeness, and lack of bias. Investors and creditors need to check how the data is defined, how it&#8217;s collected, where it comes from, and any references used. They should steer clear of sources that are unclear, biased, or potentially misleading.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Relevance\"><\/span>Relevance<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Relevance is about how well the information matches the investor&#8217;s objectives, risk tolerance, and investment timeframe. It&#8217;s important for investors and creditors to choose sources that fit their specific investment focus, whether it&#8217;s a particular industry, market, or type of investment. For instance, traders might give more weight to market data, while creditors could lean more towards financial and corporate event data. Information that isn&#8217;t directly related to their investment needs, like news about a company manager&#8217;s personal life, should be ignored.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Timeliness\"><\/span>Timeliness<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Timeliness refers to the update frequency of the sources of investment information and its speed in reflecting market changes. Investors and creditors should opt for sources that offer the most current and precise information, which can effectively track and analyze market movements and trends. Sources that are outdated or slow to reflect market changes are less useful.<\/p>\n\n\n\n<p>TEJ is at the forefront of these changes, continually adapting its strategies to leverage emerging trends. Whether it&#8217;s integrating alternative data sources into its analysis or utilizing AI for more accurate predictions, TEJ remains committed to providing cutting-edge financial data solutions.<\/p>\n\n\n\n<div style=\"border: 1px black; border-style: solid none; text-align: center; border-color: #296580; padding: 24px; margin-top: 24px; margin-bottom: 24px;\">\n<p style=\"margin: 0px; font-size: 24px; font-weight: bold; line-height: 1.5;\">Learn More about the High-Quality Investment Database by TEJ!<\/p>\n<div style=\"margin-top: 32px;\"><strong><a style=\"border: none; border-radius: 4px; background-color: #296580; color: white; font-size: 20px; width: fit-content; text-decoration: none; padding: 12px 30px 12px 30px;\" href=\"https:\/\/www.tejwin.com\/en\/solution\/quantitative-finance-solution\/\">TEJ Quantitative Finance Solutions<\/a><\/strong><\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Navigating_Common_Investment_Information_Biases\"><\/span>Navigating Common Investment Information Biases<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>After evaluating the sources of investment information, the next step is making an investment decision. Analyzing vast amounts of information is common, but not all information is accurate or complete. Here are some common biases.<\/p>\n\n\n\n<figure class=\"wp-block-image alignfull size-large caption-align-center\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.tejwin.com\/wp-content\/uploads\/Commoninformation-1024x576.png\" alt=\"where do creditors and investors obtain information to make decisions concerning a company?\" class=\"wp-image-20532\" srcset=\"https:\/\/www.tejwin.com\/wp-content\/uploads\/Commoninformation-1024x576.png 1024w, https:\/\/www.tejwin.com\/wp-content\/uploads\/Commoninformation-300x169.png 300w, https:\/\/www.tejwin.com\/wp-content\/uploads\/Commoninformation-150x84.png 150w, https:\/\/www.tejwin.com\/wp-content\/uploads\/Commoninformation-768x432.png 768w, https:\/\/www.tejwin.com\/wp-content\/uploads\/Commoninformation-1536x864.png 1536w, https:\/\/www.tejwin.com\/wp-content\/uploads\/Commoninformation.png 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Common Investment Information Bias.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Survivorship_Bias\"><\/span>Survivorship Bias<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Focusing only on surviving enterprises or targets while neglecting eliminated or failed ones leads to an overly optimistic assessment of market or industry performance. To avoid survivorship bias, collect more information, including both successful and failed cases, and objectively evaluate the overall condition and trends of the market or industry.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Look-Ahead_Bias\"><\/span>Look-Ahead Bias<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Look-ahead bias occurs in quantitative analysis when future data is used instead of the data available at that time. For example, if financial statements are retroactively adjusted or revised with data from the same period in the previous year, it constitutes future data. Utilizing such data as selection criteria for stock picking can result in a strategy that fails to accurately reflect real trading conditions.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Historical_Price_Adjustment\"><\/span>Historical Price Adjustment<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Ignoring the impact of events, such as stock splits, rights issues, dividends, etc., on stock prices when analyzing price trends leads to incorrect judgments about price changes. To avoid historical price adjustments, use adjusted stock prices to analyze price trends and pay attention to other important indicators such as the P\/E ratio and market value. Sources of investment information may encompass various biases, which can ultimately lead to inaccurate backtesting results. To address these biases, having comprehensive historical data and real-time updated point-in-time data is the only solution.<\/p>\n\n\n\n<p>TEJ provides a quantitative analysis dataset in the Asia financial market, with comprehensive delisting and listing data, enabling users to develop strategies and avoid survivorship bias. we exclusively provide users with recompiled financial report data, enhancing the precision of strategy development. Furthermore, our data retains the announcement date, crucial for understanding the most authentic price response on the announcement day. TEJ\u2019s adjusted stock prices prevent unusual fluctuations after ex-dividend dates, allowing you to compare current and past prices on the same baseline.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Impact_of_Quality_Investment_Information\"><\/span>Impact of Quality Investment Information<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Investors and creditors heavily rely on high-quality investment information. Sources of investment information, characterized by reliability, relevance, and timeliness, play a pivotal role in analyzing a company\u2019s performance, financial health, and market dynamics.<\/p>\n\n\n\n<p>Simultaneously, recognizing the impact of data bias on investment quality is paramount in quantitative analysis. Investors may achieve favorable outcomes in their quantitative models, only to face significant challenges when executing strategies in the real market. Neglecting investment bias is like overlooking the inherent variability of the market.&nbsp;<\/p>\n\n\n\n<p>In this context, having a database that automates data cleansing and addresses investment bias becomes crucial. TEJ, located in Taiwan, serves local financial and academic institutions with over 30 years of history.
