Back to Basics: PS Ratio
TransDigm Group (NYSE:TDG) PS Ratio Explanation
The PS Ratio is an excellent valuation indicator if you want to compare a stock with its historical valuation or with the stocks in the same industry. The PS Ratio works especially well when you want to compare the stock's current valuation with its historical valuation. The PS Ratio is a great valuation tool for evaluating cyclical businesses where the PE Ratio works poorly. It works the best when comparing the current valuation with the historical valuation because over time, a company's profit margin tends to revert to the mean.
When the PS Ratio is applied to the whole stock market, it can be used to evaluate the current market valuation and projected returns. In this case, the price is the total market cap of all stocks that are traded, and sales are the GDP of the country. This is how Warren Buffett estimates the broad market valuation and project future returns.
The PS Ratio does not tell you how cheap or expensive the stock is. It cannot be used to compare companies in different industries. It works better for companies within the same industry because these companies tend to have similar capital structures and profit margins. It works the best when comparing a company with itself in the past.
