Hello everyone,

I just trying an algorithm for fundamental factors, but get some confused on ‘period value’. In fact, I find something strange after comparing QC's data to macrotrend.

Let's take one example on the ticker ‘MKL' and its Return on Asset (ROA). 

On 2015-03-03, the ROA is 0.012735 from QC with peirodEndingDate = 2014-12-31.
From macrotrend, the ROA value for 2014Q4 is 1.29%

My question is: what the value ‘ROA.ThreeMonths’ and ‘ROA.SixMonths’ mean here, how to derive them?..

In other words, if I want to calculate quarterly ROA, how to do it?

Many thanks,
Arthur.C
