What: Shares of Radio Shack (NASDAQOTH:RSHCQ) took an afternoon dive today, falling as much as 23% after trade publication Debtwire revealed that the company is on the verge of a liquidity crisis.

So what: According to the report, the struggling retailer is considering hiring a financial advisor to help shore up its balance sheet, as the company is facing problems with debt maturities, negative cash flow, and excessive inventory. Radio Shack did, however, issue a statement to CNBC later in the day, saying its balance sheet was strong, with $820 million in liquidity; but, like other companies, it found reason to entertain outside advice on strengthening its balance sheet. Shares bounced back to finish down just 7% at the end of the day, and gained a bit more after hours.

Now what: Despite management's statement and the stock's recovery, it's not surprising why investors would react so strongly to such a report. Radio Shack is fighting an uphill battle against retail giants like Target, Wal-Mart, and, and has had five straight quarters of negative net income. Free cash flow, meanwhile, has run negative free three of the last four quarters. With results like that, it's only time before a liquidity crunch arrives. Radio Shack may not be on its deathbed just yet, but it's hard to see a reason to bet on this company for the long term.
