Shares of Tuesday Morning Corp. plunged 39% toward a record low in premarket trading Wednesday, after the discount home furnishings retailer said it has filed for bankruptcy, as the prolonged closure of its stores amid the COVID-19 pandemic created an "insurmountable financial hurdle." The company said it has obtained $100 million in debtor-in-possession financing so it can continue operations during the bankruptcy. The company said plans to permanently close about 230 of its 687 total stores, or 33%, as part of the reorganization. Tuesday Morning said it had initially closed all of its stores due to the pandemic, but has reopened about 80% of the stores, and over 7,300 employees have returned to work. The bankruptcy comes a little over a week after fellow retailer J.C. Penney filed for bankruptcy. The stock has plummeted 86.7% year to date through Tuesday, while the SPDR S&P Retail ETF /zigman2/quotes/206947004/composite XRT -0.43% has dropped 12.5% and the S&P 500 /zigman2/quotes/210599714/realtime SPX +0.28% has shed 7.4%.
