Dalal Street Investment Journal reports that a penny stock trading under Rs 20 should be kept under the radar as the company has recently announced a 1:1 bonus share and a 5:1 stock split. This move comes as the company secures an export order worth Rs 5,00,00,000 from Green Metals FZCO. Investors are advised to monitor the stock closely as these developments could potentially impact its performance in the market.
