There's a wealth of information in company financial statements, and it's only accessible to investors willing to look through the numbers. Here we give some ideas on how to dig deeper into a company's sales trends by comparing numbers on a company's financial sheets. Doing this can provide some valuable info.
We began by screening the clean energy industry for stocks exhibiting negative signs, or "red flags," in their sales trends, comparing growth in revenue to growth in inventory and accounts receivable.
Generally speaking, it is considered healthier if a company's revenue grows faster than its inventory and accounts receivable. Since inventory is goods not sold, a growing inventory is considered a sign of difficulty selling the company's products. Also, accounts receivable is the portion of revenue that is not yet paid, and because there's no guarantee it will ever be paid, the smaller receivables is the better.
So to illustrate these concepts, we looked through clean energy companies to find those seeing negative sales trends: growth in revenue lagging growth in inventory and accounts receivable year-over-year, as well as inventory and accounts receivable becoming a larger portion of current assets over this time period.
