Pre-market trend | Halliburton (HAL) bullish signal lights up on 5/19, can geopolitical risks continue to catalyze?

Yesterday's close saw Halliburton trigger a bullish signal above the zero line on the daily MACD chart, with a trading volume of approximately $390 million, maintaining a solid market focus in the energy equipment and services sector. The confirmation of the MACD bullish signal above the zero line indicates that the medium-term upward trend is receiving further technical endorsement, with phase buying power shifting from a wait-and-see approach to active participation. As a leading company in the global oilfield services industry, Halliburton's performance is typically highly correlated with the oil and gas capital expenditure cycle. On the news front, NATO has been reported to be considering escort operations in the Strait of Hormuz; if the blockade continues until July, some previously opposing member countries may also shift to support. The Strait of Hormuz is a critical chokepoint for global crude oil transportation, and escalating geopolitical tensions have directly heightened market concerns over oil supply security, which constitutes a structural benefit for the oil service sector—rising oil price expectations typically stimulate oil and gas companies to increase exploration and development expenditures, thereby driving order growth for oil service companies like Halliburton. The Energy Select Sector SPDR Fund rose 1.17% overall yesterday, with Exxon Mobil and Chevron both closing higher, indicating positive sector linkage. From a technical perspective, Halliburton's moving average system remains in a bullish arrangement; after confirming above the MACD zero line, if today's volume remains stable or even moderately increases, the short-term upward space is expected to further open up. Within the sector, Diamondback Energy also triggered a bullish signal, and the internal technical resonance within the oil and gas sector has enhanced the credibility of the current bullish signals
