Downward rally: When a stock is stuck in a downward-trending rally, it means it is performing below its moving average for a given time period. It is presented as a percentage of performance relative to the average. When a stock is performing below its 20-day moving average (MA or SMA) as well as its 50- and 200-day moving averages, it signals bearish momentum. All the stocks in this list are rallying below their 20-, 50-, and 200-day MAs.

Accounts receivable is a big part of revenue for many companies, but it is also a potential source of problems.

Receivables represent money earned but not yet collected, so when receivables become a larger part of the revenue reported by a company, it indicates lower-quality revenues. This is because there is no guarantee that the money will be paid back in full.

Assets: Any property or holding that has tangible value is listed as an asset. This can include cash, product inventory, accounts receivable, land, equipment, investments, and more.

There is no right or wrong proportion of current (short-term, liquid) assets and long-term assets. However, dwindling cash and current asset levels should be a concern -- it may be a sign of growing illiquidity, which can hamper or even paralyze a company.

Now that you're aware of the implications of accounts-receivable trends and negative rallies, use this list as a starting point for you own analysis.
