Small companies can create substantial wealth over a long period, but the micro-cap universe also contains businesses with weak balance sheets, poor capital allocation and growth that may not be sustainable. The purpose of this strategy is to narrow that universe systematically and identify smaller businesses that already show evidence of growth, capital efficiency and financial discipline.
The Starting Screen
The process begins with a Screener.in filter designed to combine business growth, financial quality, manageable leverage and valuation discipline:
Market Capitalisation: ₹250–₹5,000 crore
P/E: Below both the industry P/E and 20
Debt-to-Equity: Below 1
3-Year Sales Growth: Above 15%
ROCE: Above 20%
(You can also add or remove any condition and /or alter the same as per individual choices)
Each condition has a specific role. The market-cap range keeps the universe focused on smaller businesses where meaningful expansion may still be possible. The P/E filters introduce valuation discipline rather than assuming that high growth justifies any price. Debt-to-equity below 1 reduces exposure to excessive leverage, while 15%+ three-year sales growth seeks evidence of actual business expansion. ROCE above 20% adds a capital-efficiency test, helping distinguish businesses generating strong operating returns from those growing mainly through additional capital.
Screen First, Research Next
A company passing the screen is not automatically an investment candidate. The screen should be treated as a starting point, not a buy signal.
The shortlisted companies should then be examined for revenue and profit consistency, cash-flow quality, promoter holding and pledging, working capital, capital allocation, competitive position, order visibility where relevant, corporate governance and the sustainability of margins.
Build for the Long Term
This is a portfolio strategy rather than a trading strategy. Once suitable businesses have been identified and researched, positions can be established with sensible diversification. Position sizes can be adjusted according to the number of selected companies and the capital available, reducing the risk that one small company dominates the portfolio simply because it looks attractive at a particular point in time.
The central idea is to give the underlying businesses time to compound. A successful smaller company may need several years for revenue growth, profitability and capital efficiency to translate into meaningful shareholder value.
A Six-Month Review Cycle
The portfolio should be reviewed systematically every six months. The purpose is not to react to every quarterly fluctuation, but to determine whether the original investment case remains intact.
Is the business still growing?
Is profitability still healthy?
Has leverage remained under control?
Is ROCE holding up?
Has the valuation become excessive?
Has the original investment thesis changed?
Companies showing sustained deterioration or no longer meeting the underlying criteria can be removed and replaced with stronger candidates from the existing screened universe or a fresh screening exercise. In this way, the portfolio becomes self-refreshing: businesses that continue to execute can remain, while persistent laggards make room for new opportunities.
The Core Philosophy
The strategy combines five essential characteristics: smaller size, demonstrated growth, high capital efficiency, reasonable valuation and financial discipline. Rather than trying to predict which micro-cap will become the next multibagger, it seeks to build a diversified portfolio of businesses that already show evidence of these qualities.
The Screener query is only the first filter. The real process begins after the screen, through deeper fundamental research, sensible position sizing and regular monitoring. Companies that continue to execute can be allowed time to compound, while those whose underlying fundamentals deteriorate can be replaced.
Closing Perspective
Ultimately, the strategy is about creating a repeatable process rather than chasing individual stock stories. Micro-cap investing carries considerable uncertainty, but a disciplined framework can help separate promising businesses from those where growth, profitability or financial strength fail to sustain. The aim is to give quality businesses sufficient time to develop while continuously testing whether the original investment case remains valid. Over the long term, this combination of patience, research and periodic review can transform a simple stock screen into a structured approach to wealth creation.
