JS Insights was founded by Dr Jiajing Sun, a CFA charterholder since 2013 and a Fellow of the Institute of Mathematics and its Applications (FIMA). She holds a PhD from the University of Liverpool and previously served as an Associate Professor in the School of Mathematics at the University of Birmingham.
Her research and teaching span financial econometrics, time-series analysis, quantitative methods and risk modelling, with applied work in R and Python. She brings this experience to the development of JS Insights study materials and finance training.
Specialist finance education
JS Insights develops finance and quantitative learning resources that connect concepts, calculations and practical interpretation. The emphasis is on understanding why a method works, recognising the information a question is testing and applying the relevant framework carefully.
Definitions, relationships and decision rules are organised into a clear learning sequence rather than treated as isolated facts.
Selected questions, worked reasoning and reproducible examples help turn reading into active understanding.

CFA study and finance skills
Preparing for the CFA Program is not only about passing exams. It is also an opportunity to build a structured understanding of finance, develop analytical discipline, and connect technical knowledge with realistic academic or career goals.
It can be useful, but it should be viewed as part of a broader development plan. CFA study can help you build core knowledge in investment, ethics, financial reporting, quantitative methods and portfolio management. Candidates without finance experience may also need to strengthen practical skills, commercial awareness and role-specific preparation.
CFA Level I can indicate that you have started building a serious foundation in finance and are willing to commit to a demanding programme of study. It does not replace work experience, internships, technical skills or communication ability, but it may support a wider profile when presented appropriately.
Yes, in some cases. For career changers, CFA study can provide a structured way to learn finance language, concepts and analytical frameworks. The transition still depends on prior experience, target roles, networking, applications, interview preparation and the ability to demonstrate relevant skills beyond the exam curriculum.
No. The CFA Program does not guarantee a job, promotion, salary increase, visa outcome or career change. It is a respected educational pathway, but outcomes depend on many factors, including market conditions, experience, role fit, technical skills and individual performance.
Many finance roles require more than exam knowledge. Depending on your goals, useful complementary skills may include Excel modelling, financial statement analysis, valuation, statistics, Python or R, risk modelling, report writing, presentation skills and interview communication. JS Insights can help learners connect CFA topics with wider analytical and professional skills.
A good approach usually starts with understanding the exam structure, topic weights and learning outcomes, then building a realistic study timetable. Candidates should focus on concept clarity, formula understanding, active recall, question practice and review of weak areas. One-to-one tutoring can help identify gaps early and make study time more efficient.
CFA knowledge is especially relevant to areas such as investment analysis, portfolio management, asset management, equity research, risk management, corporate finance and some banking-related roles. The relevance varies by role, employer and career stage, so candidates should connect their study plan with a realistic target-role strategy.
One-to-one tutoring can provide structure, explanation and accountability. It may be especially helpful for candidates who are new to finance, returning to study after a long break, struggling with quantitative topics, or trying to connect CFA study with academic or career goals. Support can be adapted to CFA Level I preparation, finance fundamentals, quantitative methods, R, Python and related analytical skills.
Who it is for
This training is aimed at three groups: students studying economics, finance, business or quantitative methods who want clearer, more structured support than a lecture alone provides; professionals preparing for the CFA examinations or moving into roles that demand stronger quantitative, data or ESG skills; and teams or institutions that want tailored sessions on a defined topic. Teaching is grounded in academic research, professional education and hands-on R and Python work.
Planned programme areas
Each area below is in development. The descriptions show the intended scope so you can judge whether it fits your goals.
Structured help across all three levels: study planning, topic review and practice-question walkthroughs spanning quantitative methods, economics, financial statement analysis, ethics, fixed income, equity and portfolio management. The aim is to clarify difficult material and build steady study habits, not to predict questions or promise a result.
Foundations and applied practice in the methods finance relies on: probability and statistics, regression and inference, time-series analysis, and model specification, estimation and validation. For those who want to understand the methods properly rather than apply them as a black box.
Applied R for financial data work: importing and cleaning data, computing returns and volatility, statistical and econometric modelling, visualisation, and reproducible research workflows. Suited to coursework, dissertations and empirical finance projects where results need to be transparent and repeatable.
Practical Python for finance and data analysis: working with pandas and NumPy, cleaning and structuring datasets, returns and risk calculations, basic forecasting, and clear charts and reporting. Aimed at building working skills that transfer to internships, research and analyst roles.
An introduction to working with ESG and sustainable-finance data: what the main data sources and ratings measure and where they disagree, how to handle the data carefully, and how to read ESG analytics critically rather than at face value. Framed around method and evidence, with no view taken on any specific product or investment.
Workshops on the modelling behind risk measurement: volatility models, value-at-risk and related measures, monitoring methods, and the assumptions and limitations behind each approach. The emphasis is on understanding what a model can and cannot tell you, and on validating it honestly.
