Methodology
The Average P/E (μ) and the Standard Deviation (σ) are calculated excluding 20% outliers (i.e. over a range of values excluding 10% of observations from the top and 10% from the bottom of the dataset).
A P/E between (μ - σ) and (μ + σ) is considered "Fair", over a specific timeframe.
A P/E greater than (μ + σ) is defined "Overvalued", greater than (μ + 2σ) is defined "Expensive".
A P/E less than (μ - σ) is defined "Undervalued", less than (μ - 2σ) is defined "Cheap".

The 200-day moving average is a long-term indicator that takes into account the average price of a stock over the past 200 trading days. It is considered a significant level of support or resistance, meaning that when the stock price is above the 200-day moving average (i.e. margin vs moving average is positive), it is generally viewed as bullish, while when it is below, it is viewed as bearish.

The 50-day moving average, on the other hand, is a shorter-term indicator that measures the average price of a stock over the past 50 trading days. It is also viewed as a significant level of support or resistance and can be used to identify shorter-term trends.
