faint! should we use WACC to calculate ROE?

WACC can be used to calculate ROI or ROCE, but not ROE.

For ROE, you can use DDM or CAPM.

Of course I know that. I mean, in the WACC method, how to calculate ROE in the Chinese stock market !!! Since the ROM may be minus, the ROE may be also minus. It's really weird.
