In securities trading, a zero uptick is a trade that occurs at the same price as the prior trade for the same security where the last trade at a different price was lower. The higher price trade that precedes the zero uptick is called an uptick. Thus, a zero uptick is not actually an uptick. The zero uptick is sometimes called a zero-plus tick. The opposite of the zero uptick is the zero downtick. For example, if six successive trades for a stock occur at $30, $31, $31, $32, $32, and $32, three of the six are a zero uptick. The three known to be a zero uptick are the third, fifth, and sixth tick. (The first trade of the six might also be a zero uptick, too, depending upon the price of trade before that!) |
