Oh. I didn’t realize that.
There are some even more alarming NA counts if you dig deeper into certain financial statement items. For example, in my universe of 3000 stocks there are 800 NAs for the item RecvblChgTTM, and only 130 of them are NA in RecvblTTM or RecvblPTM. One would think that RecvblChgTTM would simply equal RecvblTTM - RecvblPTM. And why do I get 220 stocks with an ROE%TTM of NA? These include big companies like PM, HCA, LB, and AZO. If you use ROE%TTM and FCFTTM in ranking systems, you’re going to get way too many NAs for comfort.
