Last week, Halliburton shares set a 3-year high of 42.56. But the "doji" formed on the graph reflected buyers' doubts in the growth momentum, which resulted in a sharp drop of 11.5% from the set top. The correction stopped at the Fibonacci 23.6% level (37.6).
On Friday, the daily candlestick broke down the uptrend. If the "hammer" does not help to return above the trend line, the decline may continue to the 38.2% Fibonacci level (34.4).
