1. A stock market trend indicator comprising: a stock chart consisting of a graph showing the recent history of a particular stock, said chart having an abscissa consisting of a linear scale calibrated in units of time and an ordinate consisting of two linear scales calibrated in units of stock price and quarterly earnings, respectively; data points located on said chart corresponding to at least three recent quarterly earnings; a trend line drawn on said chart to approximate the general trend of the said recent quarterly earnings; a calculator consisting of a base member, rotatable arm, and a see-through rivet rotatably connecting said arm to said base member; said base member having a straight bottom edge, a top edge, and two side edges, said rivet being located substantially midway between said top and bottom edges adjacent one of said side edges; a percentage scale located adjacent the other of said side edges, said percentage scale having (1) a zero point located on a line which passes through the center of said rivet parallel to said bottom edge, (2) a percentage increase scale located above said zero point and calibrated to correspond with the calibration of said price and said earnings scales, and (3) a percentage decrease scale located below said zero point calibrated to read one half of the percentage increase scale for equal distances from said zero point; and said arm having a length corresponding to a specific period of time as measured on said time scale and having a pointer at the end remote from said rivet, said pointer coacting with said percentage scale, whereby when said calculator is positioned on said chart with the bottom edge parallel to said abscissa, with said see-through rivet centered on said trend line at the current price of said stock, and with said pointer overlying the extension of said trend line, said pointer will indicate the anticipated percentage increase or decrease of the stock price and quarterly earnings on said percentage scale.
