Penny Stocks Screen Criteria Under Rs 1,000 Crore And Price Under Rs 20

The screening framework behind the list targets two core price and capacity thresholds: market capitalization below Rs 1,000 crore, and share price under Rs 20, paired with a minimum daily liquidity threshold of five lakh shares traded. These criteria aim to isolate micro-cap names with meaningful liquidity relative to their valuations, though liquidity can still be thin for extended periods in many cases. The data source ACE Equity informs the screen basis for the stock universe used in this analysis.

Practical Steps For Retail Investors When Facing Penny Stock Declines

When confronted with dramatic six-month declines among penny stocks, retail investors should adopt a disciplined framework. Start with a realistic position size relative to your risk tolerance, set explicit exit levels, and verify that liquidity remains viable for the intended trade horizon. Consider analyzing each stock’s narrative–whether it has a credible business model or is primarily a momentum play–and weigh that against the price decline. The 14-stock list is a reminder that fundamentals can lag in micro-cap markets, and liquidity can evaporate quickly during downturns.
