Begins with reporting quality, cash flow and accounting; only once the numbers hold do scenarios and risk come in.

Education and Tools, Free to Use

Calculators, a paper-trading lab, the CalcuSum app and finance videos explain concepts and do the arithmetic. They never say what to buy or sell.


// Regular contribution, period by period
units = 0
cost = 0

for (period in periods) {
    price = close(period)
    units += contribution / price
    cost += contribution
}

value = units * close(last)
gain = value - cost

Open to everyone:

Calculators: The regular-contribution calculator back-tests fixed contributions into a major index. Sign in with a United User Centre account to use it; nothing is charged.

Paper Trading: Virtual fills at prices typed in by hand, with no sign-in. No assessment, no funded account and no profit share; reloading clears it.

Videos and App: Finance videos and the CalcuSum app explain concepts and calculations, free of charge.

For Investors

Research and Due Diligence

HW & YZ LLP is a consultancy focused on investment research, due diligence and market analysis. Drawing on research systems, data analysis and market-insight tools, it provides investors, companies and professional institutions with market research, investment analysis and due diligence procedures.

Standard reports

A fixed scope at a fixed price, with the delivery time stated before work starts.

Project quotations

For work outside a standard report: the scope is agreed first, then priced in a written quotation.

Scope of work

  • Market and industry research
  • Investment analysis: company facts, financials and risks
  • Due diligence procedures and findings

Scope, timetable and price are confirmed in a written quotation, and the work is delivered as a written report. No prices are published on this site.

Reports end at facts and risk findings. They give no buy, sell or hold conclusion on any security, and we give no personal investment advice, manage no money and sell no signals or trade copying.

For institutions, companies and professional investors only. Our sister firm Asolidus serves the management of operating businesses; HW & YZ serves investors.

Defined Scope
No. The calculators, the paper-trading lab, the CalcuSum app and the finance videos are free. The only paid work is research and due diligence for institutions, companies and professional investors, priced in a written quotation.
No. HW & YZ LLP provides information, education and research only, and does not advise on buying or selling any specific investment. It never accepts or holds client money, manages accounts or places trades, and sells no signals or trade copying.
Institutions, companies and professional investors, not individuals seeking personal advice. Work is either a standard report with a fixed scope and price, or a project quoted once the scope is agreed. Reports state facts and risk findings and give no buy, sell or hold conclusion.

Yes, virtually. The paper-trading lab uses only prices typed in by hand, keeps positions in the browser tab and clears on reload. There is no assessment, no funded account and no profit share, and it never touches a broker, live market data or house capital. Open /en/simulator.
Index levels, quotes and price history come from third-party public market data and are delayed: Yahoo Finance first, then Tencent and Nasdaq when it does not answer. They are supplementary reference only. A source is named only when it actually supplies the data.
On the free disclosure pages: the daily NAV and terms of the three proprietary asset pools at /en/assets, the dinner composite rate and its daily history, with any manual override or freeze marked, at /en/rates, and market notices and data-source health at /en/incidents. Each figure carries its time. These are statements of fact, not offers.
