Share prices of most of the "Z" category companies are rising abnormally in recent weeks though they had no price sensitive information (PSI) or any expansion plan amid sluggish market movement.
Within one month, some "Z" category companies' share price jumped between 8.12 per cent and 49.12 per cent while 34 companies share price rose 8.51 per cent Sunday though the market is passing a bearish mood, according to Dhaka Stock Exchange (DSE).
Following the recent abnormal price hike of these low-cap companies' share, the DSE also served show-case notices on 14 companies recently, but the companies informed the premier bourse that they had no price sensitive information for unusual price hike.
Some retail investors have already burnt their fingers as the market remained volatile over the price hike of poorly performing stocks, traders said.
"An unusual price hike of "Z" category companies amid a slow mood in the market may cause a massive loss in their portfolios," said an analyst adding that investors should be careful to put funds in the low-cap companies.
Listed companies with low capitalisation also dominated the day's gainer chart on the day though the market witnessed correction with turnover hitting seven month low.
Among the "Z" category companies, share prices of Meghna Pet Industries, Progressive Life Insurance, Sonargoan Textile, Meghna Condensed Milk, Metro Spinning, Sinobangla Industries, Modern Dyeing, Beach Hatchery, BIFC and Janata Insurance continued to surge though there was no price sensitive information.
