Dictionary of Finance and Investment Terms: trin
trin
measure of stock market strength that relates the Advance-Decline ratio (the number of issues that advanced in price divided by the number of issues that declined in price) to the advance volumedecline volume ratio (the total number of shares that advanced divided by the total number of shares that declined). For example, if 800 stocks advanced and 750 issues declined while a total of 68 million shares advanced and 56 million shares declined, the trin would be calculated as follows:
A trin of under 1.00 is considered bullish while a trin over 1.00 is considered bearish. The above trin of 0.88 is thus a bullish sign. A trin based on closing figures is called a closing trin.
