The CFO of Halliburton (HAL) Mark McCollum has left to fill the seat as CEO at Weatherford International (WFT). So far we have seen shares of WFT rally around this event. Meanwhile, the CFO's departure has been accompanied with a price top as we can see on the daily chart below.Halliburton (HAL) Daily Chart(click to enlarge)Head and Shoulders:- The daily chart shows that the bullish trend stalled as price pushed closer to 60.00. - We also saw a completed head and shoulders pattern.- Then recently, price action failed to push back above 55.00, further confirming a price top. Bearish Projection:- While a price top suggests that bulls should be exiting, it does not say that there will be a bearish trend inevitably.- This slide could just be a bearish correction within the context of a longer-term bullish trend.- With the above scenario in mind, we should anticipate support as price nears 50.00. - There is a previous pivot here and the rising trendline could also provide support. - If price does indeed reach 50.00, monitor the RSI for bullish divergence to anticipate subsequent momentum reversal back to the upside.
