Three US stocks were heavily impacted by Trump's speech on Iran this week.

President Trump's April 1, 2024 speech on the Iran conflict predicted another two to three weeks of intense military airstrikes, causing the brief recovery of the US stock market to immediately reverse and pushing oil prices above $110 per barrel.

This speech clearly Chia US stocks into two groups: winners and losers. BeInCrypto experts selected three stocks that were most heavily impacted. Among them was an energy company that benefited from the war-torn oil prices.

This list also includes two companies heavily reliant on oil, whose nascent recovery was extinguished within hours. The selection was based on price reaction, chart structure, and the extent to which their business models were directly correlated with sustained high oil prices.

APA Corporation (NASDAQ: APA)

APA Corporation (APA) is one of the U.S. stocks that has benefited most significantly from the Iran tensions. As a company specializing in oil and gas exploration , every dollar increase in crude oil prices flows directly into APA's net profits.

Trump's commitment to continued airstrikes, along with threats to attack Iran's energy infrastructure, suggests that the risk of supply disruptions will persist, thus helping to keep crude oil prices high in the near future.

On the daily chart, APA stock has increased by approximately 96% since the beginning of January 2024, forming a very clear bullish flag pattern. From March 30, 2024 to the present, the price has been trading sideways within this flag zone.

The Chaikin Money Flow (CMF) indicator – which reflects buying and selling pressure from large institutions – has consistently reached new highs throughout the price surge, currently standing at 0.18.

The continuous influx of large amounts of institutional capital confirms that this is a supported trend, not a sell-off.

On April 2nd, 2024, APA stock peaked at $43.93 but failed to break above the upper trend line of the flag pattern. A close above $43.98 would confirm a breakout, with subsequent price targets at $49.80, $55.63, and further at $65.06.

However, a break below $40.38 would cause this pattern to fail prematurely, and only a loss below $31.56 would completely invalidate the bullish structure.

Carnival Corporation (NYSE: CCL)

Carnival Corporation (CCL), however, is at the opposite extreme of the oil price chain . As the world's largest cruise line, fuel accounts for the largest proportion of CCL's volatile costs.

Rising oil prices immediately reduced profit margins, while prolonged geopolitical tensions made customers hesitant to book tours, creating two of the strongest obstacles compared to many other industries.

Since peaking at $34.05 on February 6, 2024, Carnival's stock price has consistently fallen within a descending channel on the daily chart, losing approximately 10% in the past month as oil prices have surged.

A positive divergence formed from mid-November 2023 to the end of March 2024, when prices created new Dip while the Relative Strength Index (RSI) created higher Dip .

This divergence indicates weakening selling pressure, helping prices recover as the market anticipated a reduction in tensions earlier in the week.

However, Trump's speech reversed the scenario. The recovery stalled, and CCL prices fell 3.54% on April 2, 2024, due to concerns that a prolonged trade war would keep oil prices around $110 per barrel.

Technically, this positive divergence has not yet been broken, meaning that if the situation cools down again, prices could still recover. But if oil prices remain high, the downtrend will still prevail.

If the price surpasses $26.77, short-term buying pressure may return, with the $30.13 level acting as a neutral structural boundary. Conversely, the nearest support level is $23.80.

A break below $21.45 would confirm the bearish pattern has been triggered, with the next targets being $20.19 and $18.41 respectively.

United Airlines Holdings (NASDAQ: UAL)

United Airlines Holdings (UAL) was the most volatile and volatile stock among US securities this week . Jet fuel typically accounts for 25-35% of total operating costs, making airline stocks highly sensitive to fluctuations in oil prices.

Whenever oil prices rise, airlines' profit margins immediately decline because they cannot increase fuel surcharges for passengers quickly enough.

Between March 27, 2024 and April 1, 2024, UAL's stock price increased by 14%. Expectations of de-escalation of hostilities helped cool oil prices, boosting the tourism industry. This upward momentum pushed UAL's price above the 20-day Exponential Moving Medium (EMA), a short-term trend indicator, to around $93.71.

Trump's speech wiped out the recovery. UAL stock has fallen approximately 8% from its peak on April 1, 2024, closing at $92.21 on April 2, 2024, down 3% for the day. This decline has pulled the stock below the 20-day EMA, which is significant because the last time UAL broke above this line was on February 3, 2024, when the price surged 9%. Losing this level now also means UAL no longer has short-term support.

The overall impact on the market is also significant. From the beginning of February 2024 to the present, UAL shares have fallen 28%, from $118.88 to a low of $84.62 on March 30, 2024. The main reason is concern about profit margins being affected by rising oil prices.

If the market opens with positive news early next week, a rebound of the $93.71 mark would help UAL regain the 20-day EMA support level.

If this level is breached, the next targets will be $97.71 and $101, with $101.75 also close to the 50-day and 100-day EMAs. If UAL surpasses $101.75, the price will be above all the key moving Medium for the first time since the beginning of February 2024.

However, if oil prices remain above $110 and the conflict continues, $84.62 will be the final support level. If this level is breached, the UAL price could continue to fall further.
