Atul Suri

CEO & Fund Manager

35 years of
watching markets.

“

Atul Suri has spent more than three decades studying and investing in Indian equities. His journey began in 1991 as a fundamental analyst at Parag Parikh Financial Advisory, where he learned to look beyond the story and understand what really sits behind a business — its earnings, its numbers, and the quality of its growth.

He later pursued a master’s degree in finance in Sydney, adding a quantitative perspective to his fundamental understanding of markets.

The investment belief

Great investments
begin with strength.

We look for strength in two places: the business and the market. Quality identifies businesses with improving earnings. Momentum confirms price strength. When either weakens, discipline tells us when to exit.

01

Earnings strength

Quality

We invest in businesses with consistent and accelerating Sales, Profit and ROE, measured against the BSE 500. Quality defines the universe — only businesses with the strength to sustain growth qualify.

How we identify quality
02

Price strength

Momentum

A good company need not be a good stock. We look for short-, medium- and long-term price strength, with all three trends confirming before we enter.

Buy strength, sell weakness
03

Discipline

Exit

When earnings deteriorate or price momentum breaks down, we exit. Rules trigger the decision — without emotion, exceptions or discretionary overrides.

The process end to end
How we invest

A loop, not
a checklist.

The universe narrows at every stage — from 500+ listed businesses to a focused, closely monitored portfolio. As capital is released from an exit, it flows into the next opportunity — and the process begins again.

Why Marathon

Built to move
when markets do.

Four structural choices that traditional funds rarely make — designed to find leadership, protect capital and adapt when the market changes.

One decision framework

  1. 01 Not a black box 2 Filters: earnings + price

    Fundamental Quality Meets Price Momentum.

    We do not buy a turnaround story, or a speculative chart. A holding qualifies only when improving earnings and sustained price leadership point in the same direction.

  2. 02 Capital first 100% Exit when a rule breaks

    No story traps. No averaging down.

    When earnings deteriorate or the long-term trend breaks, the position is sold in full. The rule is set before there is anything to defend — without hope, exceptions or emotion.

  3. 03 Let winners run 3.5× Realised average win / loss

    Small losses. Outsized gains.

    The aim is not to be right all the time. It is to cut detractors quickly and give genuine leaders time to compound — a structure built for positive asymmetry.

  4. 04 Follow leadership 20–25 High-conviction positions

    Capital moves as India’s leadership changes.

    Unconstrained by benchmark weights or a static sector mandate, the portfolio can rotate towards the earnings and price trends emerging across the listed market.

See how the framework works
“

Markets do not care about opinions; they only reflect strength and weakness. When you align capital with sustained price leadership, compounding takes care of itself.
