If you are going to make this type of comparison between MAY and BRK you should compare market cap not share price. BRK at 1.2c has a market cap of $62m for its 11 million barrels. MAY at 2.2c has a market cap of $72.4m for its 15 million barrels. If BRK is the measuring stick then MAY's market cap should be 36.4% higher than BRK's (ie MAY 15m barrels is 36.4% more than BRK 11m barrels), which is a market cap of $84.6m, and equates to a share price for MAY of around 2.6c. This type of analysis would rate MAY at 2.2c comparatively undervalued with reference to BRK, but for myself I don't find these types of comparisons particularly helpful.
