2026-09-27 Release 7.0

MantaWealth - Revised Diversification screen

• UX improvements, including easier-to-read headline figures (expected return, volatility, and CVaR with VaR), and reworked diversification chart.
• A new Largest risk shifts panel lists only the holdings whose risk the change moves, split into less and more risk.
• A new Risk by holding table puts each holding's contribution to CVaR and to volatility side by side.
• A new Risk kept metric shows how much of a holding's own tail risk (CVaR) is left once it sits in the portfolio: 100% means the rest of the portfolio offsets none of it, and below 0% marks a hedge. For the whole portfolio, it shows how much of its holdings' combined risk remains after diversification.
• A Quality of Analysis line reports how much of the portfolio's risk is modelled and how much is explained by common risk factors.

See Diversification for a full description.

• MantaWealth / MantaAPI - Performance Attribution Analysis: performance enhancements.
• MantaAPI - Credit Risk: preparatory work for the upcoming Credit Risk analytics.

2026-08-16 Release 6.5

MantaWealth - Instrument Screener

• A new Screener button next to the instrument search field opens an Equities and Fixed Income instrument screener.
• Equities screen on exchange, sector, market cap, price, EPS, dividend yield, 1- and 5-day return, average volume, and pre-computed signals (new 50/200-day highs and lows, analyst target, book value).
• Fixed Income screens on issuer sector, geography, country, region, industry, coupon type, currency, face value, yield, duration, coupon rate, outstanding volume and maturity — and default to bonds still available to buy.
• Results are sortable on any column, and any match can be added straight into the portfolio.

2026-08-09 Release 6.4

• MantaWealth / MantaAPI - Performance & stability: broad performance improvements and stability hardening across the platform.
• MantaAPI - Reporting endpoint: new options:
  • Section selection: any of the report's sections — portfolio composition, factor exposure, risk analytics, stress testing, performance analysis and cashflow forecast — can now be individually included or omitted per report.
  • Before/after comparison: reports can now be generated in a comparison mode that presents a portfolio's current holdings alongside a proposed rebalanced version — composition, factor exposure, risk metrics, stress testing and cashflow forecast shown side by side.
• MantaWealth / MantaAPI - Performance Attribution methodology update: the PAA CAPM curve is now built purely from historical data. Synthetic data reconstruction has been removed from the curve calculation, so attribution results reflect only genuine observed prices.

2026-06-24 Release 6.0

MantaWealth / MantaAPI - Methodology update: VaR & CVaR

• VaR and CVaR are now computed on demeaned returns — the historical mean is subtracted before estimating the loss quantile — so tail risk is measured independently of expected return (Rockafellar–Uryasev–Zabarankin, 2006).
• Portfolios with a positive historical drift will therefore show higher CVaR/VaR; those with a negative drift, lower.
• CVaR and VaR (incl. contributions) are no longer published above a monthly horizon (quarter, YTD, year), where time-scaling is unreliable under fat tails — long-horizon and crisis tail risk is covered by our stress-testing / scenario analysis instead.

2026-05-17 Release 5.5

• MantaWealth - Private Asset Management: private assets are now managed directly from the MantaWealth front-end, bringing the proxy-based coverage previously available on MantaAPI into the UI.
• MantaWealth / MantaAPI - Report Configuration: organisation-level defaults for PDF Investment Proposals (co-branding, report sections) can now be saved and reused, and overridden per-report when needed.

2026-04-27 Release 5.4

• MantaWealth - Investment Proposals: a new PDF Report button generates a professionally formatted, client-ready portfolio analysis in a single click — covering allocation, risk metrics, and rebalancing recommendations. Ideal for client meetings, advisory reviews, and compliance documentation.

See a sample output here: Investment Proposal (example PDF).

Publication of new endpoint for portfolio level analytics including:

• CVAR over daily, weekly and monthly periods for the 2.5%, 5% and 10% quantiles
• VAR over daily, weekly and monthly periods for the 2.5%, 5% and 10% quantiles
• Volatility over daily, weekly and monthly periods for the 2.5%, 5% and 10% quantiles
• Diversification ratio: metric used to quantify the level of diversification within a portfolio. MantaRisk uses the definition according to Choueifaty and Coignard (2008) where this ratio considers both the number of assets in the portfolio and the correlations between them. A higher diversification ratio indicates a more diversified portfolio, meaning the assets are less likely to move in the same direction, reducing overall portfolio risk.
• Expected return: defined as the average return over 5 years on a daily, weekly or monthly timeframe
• R Squared: proportion of the variance explained by the risk factors. 1 - R^2 is therefore equivalent to the idiosyncratic risk i.e. the portion of the portfolio which cannot be explained by the risk factors.
