Watching the trends When that red line (AR growth) crosses above the green line (revenue growth), I know I need to consult the filings. Similarly, a spike in the blue bars indicates a trend worth worrying about. Medtronic's latest average DSO stands at 87.1 days, and the end-of-quarter figure is 85.1 days. Differences in business models can generate variations in DSO, and business needs can require occasional fluctuations, but all things being equal, I like to see this figure stay steady. So, let's get back to our original question: Based on DSO and sales, does Medtronic look like it might miss its numbers in the next quarter or two?
