Right? The “Methodology” says “The calculations are based on the share price the day before Mr. Einhorn’s views became public” but there’s no shared zero point: all the lines never cross in one place. So on the day of his comments the stocks are down 20% or up 2% or somewhere in between from … what? Not the day before his comments, when they’re down I guess 15% or up 1% or somewhere in between (from what?), or 5 days before, or … I dunno. Perhaps “views became public” and “comment” are separate, so the zero point floats in relation to the comments? But then there’s a chart for companies he’s bullish on and it includes Sprint Nextel, which *never touches zero*! Its stock price is always above itself. Or something. Anyway.
The more frequently you monitor your portfolio, the more likely you are to observe a loss. This is likely to cause short-sighted decisions and could hurt your investment performance. If you are checking your portfolio more than once per quarter, you’re doing it too much.
