It’s official: Bell Microproducts (BELM.PK) has lost its Nasdaq listing due to late financial filings, as feared, and now trades on the pink sheets. The distributor of disk-dives and other tech products had warned months ago that this was a possibility, but the stock fell dramatically over the last few days as investors faced up to the situation. The stock, which fell 46% from Thursday’s close through yesterday, today is on the mend: on the pinks, the stock is up 24 cents, or 14.5%, at $1.90.
