Quote from tradestrong:
You're putting up a chart comparing the restaurant industry to the S&P 500?. jeez...why don't you compare the energy industry to the financial industry...after all, it shouldn't matter whether their volatility and correlations are completely different....right?
Restaurant stocks have much higher volatility then the S&p 500...so naturally, they will either gain or fall as a whole at a much higher percentage.
Now compare the restaurant industry to the financial industry (which historically has a much lower beta), and see which industry is suffering more.
"Theoretically", with a much lower beta, the restaurant industry should be crashing at a much higher rate than the financials, but the reason they aren't is because financials suffer at a much higher degree during a recession than the restaurant industry, (and of course the subprime crisis is compounding the carnage.), but anyways, the point is that restaurants are going to suffer much less than most industries in a bear market.
You can't just willy nilly pick a benchmark to use as "a matter of fact" for comparison of an industry.
