To quote Buffett, ‘Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace…’ One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Grammer became profitable within the last five years. Most would consider that to be a good thing, so it’s counter-intuitive to see the share price declining. Other metrics may better explain the share price move.

Revenue is actually up 1.3% over the time period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.
