A stock price movement forecast method of forecasting that current values of stock names indicate extreme values or approach to the extreme values only in a lamination state of F to F5 division marks, said method comprising:
- a) a data preparation process of extracting respective data of stock price time series D, stock price smooth time series y, moving tendency value time series b5, b4, b3, b2, b calculated from said stock price time series, standardized time series B5, B4, B3, B2, B and division time series F5, F4, F3, F2, F calculated from said respective time series from a storage device;
- b) a process of displaying a time series chart in which the time series is shown on the abscissa, and said stock price time series D and said stock price smooth value time series y are shown on the ordinate;
- c) a process of shifting said moving tendency value time series b5, b4, b3, b2, b on a natural horizontal line by 8P, 4P, 2P, P, ½P time series from said stock price time series D and said stock price smooth value time series y, and displaying the moving tendency value time series on said time series chart;
- d) a process of putting an upper and lower value division of the moving tendency value time series b5, and placing the division time series F5 to be adjacent to a reference line to dispose a mark band, and displaying F5=H (F5=L) above (below) said reference line with a predetermined mark in accordance with said stock price time series D and said stock price smooth value time series y on said time series chart;
- e) a process of putting an upper and lower value division of the moving tendency value time series b4, and placing the division time series F4 to be adjacent to the reference line to dispose the mark band, and displaying F4=H (F4=L) above (below) said reference line with the predetermined mark in accordance with said stock price time series D and said stock price smooth value time series y on said time series chart;
- f) a process of putting the upper and lower value division of the moving tendency value time series b3, and placing the division time series F3 to be adjacent to the reference line to dispose the mark band, and displaying F3=H (F3=L) above (below) said reference line with the predetermined mark in accordance with said stock price time series D and said stock price smooth value time series y on said time series chart;
- g) a process of putting the upper and lower value division of the moving tendency value time series b2, and placing the division time series F2 to be adjacent to the reference line to dispose the mark band, and displaying F2=H (F2=L) above (below) said reference line with the predetermined mark in accordance with said stock price time series D and said stock price smooth value time series y on said time series chart;
- h) a process of putting the upper and lower value division of the moving tendency value time series b, and placing the division time series F to be adjacent to the reference line to dispose the mark band, and displaying F=H (F=L) above (below) said reference line with the predetermined mark in accordance with said stock price time series D and said stock price smooth value time series y on said time series chart;
- i) a process of outputting said standardized time series B5, B4, B3, B2, B and said division time series F5, F4, F3, F2, F, and displaying upper (lower) value approach marks classified by a magnitude, in an area above an upper dividing line Vt (below a lower dividing line VL), in an approach signal T1U (T1L) in case of Bt−2<Bt−1>Bt (Bt−2>Bt−1<Bt) and F2t=H (F2t=L), an approach signal T2U (T2L) in case of F2t, F3t=H (F2t, F3t=L), an approach signal T3U (T3L) in case of F2t, F3t, F4t=H (F2t, F3t, F4t=L), and an approach signal T4U (T4L) in case of F2t, F3t, F4t, F5t=H (F2t, F3t, F4t, F5t=L), respectively;
- j) a process of outputting said moving tendency value time series b, said standardized time series B and said division time series F5, F4, F3, F2, F, and displaying upper (lower) extreme value marks classified by the magnitude in corresponding extreme value signal X1U (X1L), X2U (X2L), X3U (X3L), X4U (X4L), respectively, when said moving tendency value time series b cut the horizontal line, that is, in case of SIG (bt−1)< >SIG(bt) and F2t=H (F2t=L), in case of F2t, F3t=H (F2t, F3t=L), in case of F2t, F3t, F4t=H (F2t, F3t, F4t=L) and in case of F2t, F3t, F4t, F5t=H (F2t, F3t, F4t, F5t=L);
- k) a process of confirming moving tendency value curves (to b5E)→(b4S to b4E)→(b3S to b3E)→(b2S to b2E)→(bS to bE) synthesized from said moving tendency value time series b, b2, b3, b4, b5 as the moving tendency value curves of said stock price time series D and said stock price smooth value time series y;
- l) a process of reading a stock price behavior only with a combination of Ft to F5t upper (lower) value marks appearing a last term division mark area, that is, forecasting that a stock price is descending consistently for an 8P period at minimum when the Ft to F5t marks are laminated and displayed below said reference line and that the stock price is a lowered extreme value consistently for a 4P period at minimum when the Ft lower value mark disappears and the F2t to F4t marks are laminated and displayed below said reference line;
- and
- m) a process of forecasting the stock price behavior based on the divisions and magnitudes of said approach marks or said extreme value marks.
