Phillips 66 (MEX:PSX) Median PS Value Explanation
This valuation method assumes that the stock valuation will revert to its historical (10-Year) mean in terms of PS Ratio. The reason we use PS Ratio instead of PE Ratio or PB Ratio
is because PS Ratio is independent of profit margin, and can be applied to a broader range of situations.
