A support or resistance level is sometimes described as a pivot point. When price drops down to reach a support level, it typically pivots higher; similarly, when price comes up to a resistance level it generally pivots lower. When price actually breaks through at the pivot point instead of pivoting, this suggests further movement in that direction. See our ChartSchool article on Support and Resistance.

Originally used by floor traders, Pivot Points use the prior period's high, low, and close to estimate future support and resistance levels. Adding a Pivot Points overlay to the chart allows analysts to easily see when price action moves above or below these potential support and resistance levels. See our ChartSchool article on Pivot Points.

See our ChartSchool article on Point & Figure Charts.

An indicator that compares the performance of one security against that of another by plotting the two as a ratio. For example, Google can be compared to the S&P 500 with a ratio of the prices (Google/S&P 500). Google is outperforming when the ratio rises and underperforming when the ratio falls. See our ChartSchool article on Price Relative.

The P/E ratio is figured by dividing the price of a stock by the company earnings per share. For example, a stock selling at $50, with earnings at $5 per share for the previous year, has a P/E ratio of 10 (50/5 = 10). This value is also called the multiple.

A security or index whose correlation with another security or index is so strong that it is used as a substitute for the other. For example, General Electric has a very high correlation to the performance of the S&P 500. As GE goes, so goes the S&P 500. Therefore, GE can be used as a proxy for the S&P 500.

The right to sell a stock or commodity future at a given price before a given date. The owner of the put option is speculating that the price of the stock will go down and is therefore bearish.

Based on CBOE statistics (http://www.cboe.com/), the Put/Call Ratio equals the total number of puts divided by the total number of calls. When more puts are traded than calls, the ratio will exceed 1. As an indicator, the Put/Call Ratio is used to measure market sentiment. When the ratio gets too low, it indicates that call volume is high relative to put volume and the market may be overly bullish or complacent. When the ratio gets too high, it indicates that put volume is high relative to call volume and the market may be overly bearish or in panic. StockCharts.com charts the Put/Call ratio under the symbol $CPC.
