The quote is funny but wrong. If you measure everything in ton of cash you don't understand what happens. Ratios are powerful (especially the changes over time)

The quote is funny but wrong. If you measure everything in ton of cash you don't understand what happens. Ratios are powerful (especially the changes over time) but are clue of something that need to be investigated. One great example, the cash ratios of Walmart were very similar to the one of broken company. Except that it was their operating model to call for having few cash on hand.
