Bull Trap
A false signal indicating that a declining trend in a stock or index has reversed and heading upwards when, in fact, the security will continue to decline.
Investopedia Commentary
A bull trap often causes some investors to buy the stock, but because the stock continues to decline after the initial signal, those who bought in are "trapped" in a bad investment.
