Why there is this huge difference?
I am not able to reconcile Yahoo's answer of 5.75%, even using their definition for ROA of:
Return on Assets
Formula: Earnings from Continuing Operations / Average Total Equity
This ratio shows percentage of Returns to Total Assets of the company.
This is a useful measure in analyzing how well a company uses its
assets to produce earnings.
I suspect the "Average Total Equity" in their formula is a typo, but using either measure I cannot come up with 5.75% for any 12-month period.
I can, however, match MarketWatch's answer by looking at the 2016 fiscal year totals and using a "traditional" formula of Net Income / Average Total Assets:
Total Assets 394.34 226.71
Net Income 120.78 16.88
I'm NOT saying that MatketWatch is right and Yahoo is wrong - MW is using fiscal year totals while Yahoo is using trailing 12-month numbers, and Yahoo uses "Earnings from Continuing Operations", but even using that number (which Yahoo calculates) I am not able to reconcile the 5.75% they give.
