What do PMS and AIF desks need from a quant research tool that retail platforms usually do not provide?

Four things come up repeatedly: point-in-time fundamental history so a backtest uses only what was knowable on each past date, source-linking so every figure traces to a filing, line and date, reporting that survives a compliance or client review, and multi-user workflow so a team shares one version of the research. Retail tools are usually optimised for a single investor acting on current data, which is a different job.

Is a retail quant platform good enough for a small PMS or family office?

Often yes for idea generation and for price-based analytics. The limits tend to show up at the audit and reporting stage, when someone asks where a number came from, or when a backtest has to be defended using the data that existed at the time rather than today's restated figures. Many desks run a retail tool alongside a research layer rather than replacing one with the other.

Why does point-in-time data matter so much for an institutional desk?

Companies restate and reclassify results, and index membership changes. If a backtest reads today's cleaned-up history, it silently assumes knowledge the manager did not have, which flatters results. Point-in-time storage keeps each figure with the date it became knowable, so a test reflects the decision that was actually possible.

What should a desk ask a vendor before buying?

Ask how the fundamental history is stored and whether restatements are versioned, whether every displayed figure links back to a source document, what coverage exists across equities and mutual funds, how exports and reports are produced for committee and client use, and how many users a licence supports. The answers separate a research system from a screener.

Quant Research Tools for PMS and AIF Desks: What Changes at Institutional Scale

An institutional desk needs the same analytics a retail quant toolkit provides, plus four things that only matter once other people’s money and a compliance file are involved: fundamental history stored as it stood on each past date, every figure traceable back to its source document, output that survives a committee or client review, and a workflow built for a team rather than one person. This piece walks through what actually changes when a portfolio management service (PMS), an alternative investment fund (AIF) or a family office adopts quantitative research tools, and where a platform like Altys Labs fits. That is a statement of focus, not a claim of superiority; several tools in this market are good at what they set out to do.

The retail toolkit is not wrong, it is aimed elsewhere

India now has a genuinely capable set of quant and rule-based investing tools. They screen, they compute risk and return statistics, they show factor exposures, they backtest a rule against price history, and several connect to a broker so a strategy can be taken live. For a self-directed investor running their own capital, that is a complete loop, and there is nothing second-rate about it.

The loop changes shape at a professional desk. A PMS or AIF manager is not just deciding what to hold. They are also answering, sometimes months later, three separate questions: why did we hold it, what did we know when we decided, and can you show me. A tool designed around the first question alone will feel thin the moment the other two arrive. The gap is rarely about missing metrics. If anything, retail platforms often publish a longer metrics glossary than institutional systems do. The gap is about provenance, history and process.

Point-in-time fundamentals, not just point-in-time prices

Most backtesting tools handle price history correctly. Prices are adjusted for splits and bonuses, and a daily close is a daily close. Fundamentals are the harder half of the problem, and the half that quietly breaks institutional work.

Reported financials move after the fact. Companies restate, reclassify segments, change accounting policy, absorb acquisitions and adopt new standards. A database that stores only the current version of the past will tell you a company’s FY22 revenue as it is understood today, not as it was reported in the quarter you would have acted on. Results also arrive with a lag: a March quarter is not knowable in April. If a backtest reads a figure before the market could have seen it, the strategy is being scored on information it never had.

That is lookahead bias, and it does not announce itself. It shows up as a strategy that tests beautifully and behaves ordinarily. For a desk that has to justify a systematic process to an investment committee or a client, a result that cannot be reproduced under period-correct data is not usable evidence. We cover the mechanics in why point-in-time data matters, and the practical implication is simple: ask any vendor whether restatements are versioned with the date they became knowable, or whether the history is simply overwritten.

Related to this, an institutional universe has to include companies that no longer exist. Delistings, mergers and index exits are part of the record. A universe assembled from today’s index constituents contains only survivors, which is a second, independent way for results to look better than they were.

Auditability and source-linking

The single most common institutional requirement, and the one most often missing, is the ability to click a number and see where it came from.

At a desk, a figure in a note eventually gets challenged. An analyst says the operating margin compressed; a portfolio manager asks whether that is the reported figure or a normalised one, whether it is standalone or consolidated, and which filing it came from. Reconstructing that by hand across dozens of names is slow enough that in practice it does not happen, and the number goes unverified.

Source-linking means every displayed value carries its lineage: the document, the line item within it, the reporting period, and the date it became available. That has three effects. It makes review fast, because the check is a click rather than an afternoon. It makes disagreement productive, because two analysts can argue about interpretation instead of about whose spreadsheet is right. And it makes the research file defensible later, when someone reviews a past decision without the benefit of the conversation that produced it.

A related distinction worth asking about: which numbers are computed from filings and which are estimated. A ratio derived arithmetically from reported line items has a different status from a figure a language model inferred from text. Both can be useful. They should not be presented identically, and a desk needs to know which is which.

Reporting that survives a compliance review

Institutional output has readers who were not in the room. A quarterly investment committee pack, a client review, an internal risk note, an audit request: each has to stand on its own.

Practically, this means a research tool at a professional desk needs to produce artefacts, not just screens. A saved screen is a live object that changes when the data changes, which is exactly wrong for a record of a past decision. What a desk needs alongside it is a dated, fixed output: the universe as it stood, the criteria applied, the values used, and the sources behind them, exportable to a document or spreadsheet that can be filed.

Two adjacent points are worth stating plainly. First, none of this is a substitute for the firm’s own regulatory obligations under its PMS or AIF registration; software supports a process, it does not discharge a duty. Second, a tool that generates recommendations is a different category of product with different regulatory consequences for the vendor and for you. A research platform that computes and cites, leaving judgement to the manager, is deliberately narrower. Altys Labs is not a broker, not a tip service and not a SEBI-registered research analyst or investment adviser.

Coverage across equities and funds

Retail quant tools usually centre on listed equities, which is sensible because that is where their users act. A professional desk’s coverage requirement is wider in two directions.

The first is depth per company. Screening on ratios is table stakes. Judging a business needs the material behind the ratios: filings, earnings-call transcripts, management guidance and how it has been revised, shareholding patterns including promoter pledge and institutional flow, and segment level detail. This is the raw material of an actual thesis rather than a factor score, and it is what turns a systematic shortlist into an approved holding. Our note on how PMS firms research Indian stocks walks through where each of these enters the process.

The second is asset class. Family offices and MFDs hold mutual funds as well as stocks, and multi-asset mandates need both analysed on comparable terms: fund holdings and their overlap with direct positions, manager behaviour over time, portfolio-level exposure once funds are looked through. A tool that covers only one side leaves the aggregation to a spreadsheet.

Workflow for a team, not an individual

The last difference is organisational and easy to underrate. A retail tool assumes one user with one set of watchlists. A desk has an analyst who builds the model, a PM who challenges it, a risk or compliance function that reviews it, and a client-facing person who explains it.

That implies shared objects rather than personal ones: a screen or model one person builds and another can open, comment on and reuse. It implies versioning, so a change to a model is visible rather than silent. It implies access control, because not every user should see or edit everything. And it implies continuity, so that when an analyst leaves, the work does not leave with them. These are unglamorous requirements and they decide whether a tool becomes the desk’s system of record or one person’s private utility. The broader shape is covered in the institutional equity research workflow.

How Altys approaches this

Altys Labs is an equity research and fundamental analysis platform for Indian stocks (NSE and BSE) and Indian mutual funds, built for professional users: PMS firms, AIFs, family offices and MFDs. It is currently invite-only, in private preview. Stated as focus rather than as any claim of being better:

India-first and India-deep. Filings, concall transcripts, management guidance, shareholding, macro series, FII and DII flows, factor scores and mutual-fund data in one place.
Point-in-time by design. Data kept as it stood on each past date, so research and backtests reflect what was knowable then.
Source-linked. Figures trace back to filing, line and date.
Calculated, not guessed. Numbers computed from filings, with forecasts from explicit statistical methods rather than a language model estimating a growth rate.
Tools on top. Screening, modelling, forecasting and backtesting against the same data layer.
