Trump, Twitter & Truth Social: How to Move Markets like a Pro

This is not a political post, just a compilation of times The President affected markets using social media. This list does not include the many times he affected markets with comments outside of social media or through government orders. There were a couple smaller cases like Boeing, Lockheed, and Toyota, but those barely lasted into market close. If there are any I’m missing please let me know.

Tl;dr: you should probably, sadly, be watching what this dude is saying. 18 instances using social media alone. You can find the Truth Social live feed under the our Live Data Page.

3/23/2018 SPY: -2.10%

Early that morning, The President refused to sign the $1.5 trillion Omnibus Spending Bill. I am considering a VETO of the Omnibus Spending Bill based on the fact that the 800,000 plus DACA recipients have been totally abandoned by the Democrats (not even mentioned in Bill) and the BORDER WALL, which is desperately needed for our National Defense, is not fully funded. In the wake of the tariff spat that he had also triggered the day before with China, markets remained down for the duration of the day, until, rather unexpectedly, he signed the bill that SAME day, commenting to journalists;“I will never sign a bill like this again. As a matter of national security, I’ve signed this omnibus bill.”. Markets bounced slightly before close on the good news and boomed the following Monday (3/23 was a Friday) after news came out that China and the U.S. were going into negotiations.

4/2/2018 SPY: -2.23%

Before the market opened, The President made a post criticizing Amazon for taking advantage of the USPS: Only fools, or worse, are saying that our money losing Post Office makes money with Amazon. “THEY LOSE A FORTUNE, and this will be changed. Also, our fully tax paying retailers are closing stores all over the country...not a level playing field!” Amazon closed -5.2% for the day, markets were down substantially as well, thanks in part to China issuing more tariffs.

12/4/2018 SPY: -3.24%

A fairly tricky day, not much was going on aside from 3Y and 5Y yield curve inversion, it didn’t help that The President was also blasting China that day, commenting “President Xi and I want this deal to happen, and it probably will. But if not remember,...... I am a Tariff Man.” The posts also suggested that a “real” deal with China was still uncertain.

12/21/2018 SPY: -2.06%

Two days after a rate hike (which greatly displeased him), the President made matters worse by taking to Twitter and actively threatening to keep the government shut down: ”....... If the Dems vote no, there will be a shutdown that will last for a very long time. People don’t want Open Borders and Crime!” Government shutdowns are typically very unwelcome to markets.

12/24/2018 SPY: -2.71%

On Christmas day, the worst ever, The President took his first shot at removing Jerome Powell. Markets immediately dipped after his post: “The only problem our economy has is the Fed……” Reports that same day began circulating that he had been looking into removing Powell from office.

https://x.com/realDonaldTrump/status/1077231267559755776

5/13/2019 SPY: -2.41%

The President tweets: “I say openly to President Xi & all of my many friends in China that China will be hurt very badly if you don’t make a deal because companies will be forced to leave China for other countries. Too expensive to buy in China. You had a great deal, almost completed, & you backed out!” and only bounced later in the day after the President remained hesitant about slapping an additional $325 billion in tariffs.

8/23/2019 SPY: -2.59%

This tweet was particularly flagrant: “Our great American companies are hereby ordered to immediately start looking for an alternative to China, including bringing your companies HOME and making your products in the USA. I will be responding to China’s Tariffs this afternoon. This is a GREAT opportunity for the United States.” Not that the President has the powers to enforce such a thing, but hope was now diminishing that a trade deal would ever be made, and markets were spooked.

4/2/2020 SPY: +4.22%

The President took a different route, this time taking steps to bring oil prices up after record lows due to COVID. Just spoke to my friend MBS (Crown Prince) of Saudi Arabia, who spoke with President Putin of Russia, & I expect & hope that they will be cutting back approximately 10 Million Barrels, and maybe substantially more which, if it happens, will be GREAT for the oil & gas industry! WTI Crude Oil spiked 26% off of the post alone. Markets also boomed.

https://x.com/realDonaldTrump/status/1245720677660925952?s=20 

4/22/2020 SPY: +2.29%

Another simple post that led to a peak spike of 32% and a close of 19% for WTI Crude. The President merely commented: I have instructed the United States Navy to shoot down and destroy any and all Iranian gunboats if they harass our ships at sea. The general market also climbed, though it's harder to say the post was entirely responsible for that.

Crypto finally got a mention, and a big one at that: A U.S. Crypto Reserve will elevate this critical industry after years of corrupt attacks by the Biden Administration, which is why my Executive Order on Digital Assets directed the Presidential Working Group to move forward on a Crypto Strategic Reserve that includes XRP, SOL, and ADA. I will make sure the U.S. is the Crypto Capital of the World. BTC and ETH were mentioned shortly after in a follow-up post, and saw gains of over 10%. XRP gained over 30%, SOL over 20%, and ADA 68%.

4/9/2025 SPY: +9.52%

 The President comments:  Based on the lack of respect that China has shown to the World’s Markets, I am hereby raising the Tariff charged to China by the United States of America to 125%, effective immediately.  For countries that were playing ball, a 90 day tariff pause was declared. I have authorized a 90 day PAUSE, and a substantially lowered Reciprocal Tariff during this period, of 10%, also effective immediately. Thank you for your attention to this matter! Markets spiked at historical rates.

4/21/2025 SPY: -2.36%

The President took another stab at an attempt to remove Powell from office “reigniting” worries of an over-reach of power and an active attempt to meddle with the independent bank.  With these costs trending so nicely downward, just what I predicted they would do, there can almost be no inflation, but there can be a SLOWING of the economy unless Mr. Too Late, a major loser, lowers interest rates, NOW. The post goes on, but it was one of the funnier ones he made.

5/21/2025

Freddie Mac and Fannie Mae stocks both exploded well over 30% in value after The President truthed: I am giving very serious consideration to bringing Fannie Mae and Freddie Mac public. I will be speaking with Treasury Secretary Scott Bessent, Secretary of Commerce Howard Lutnick, and the Director of the Federal Housing Finance Agency, William Pulte, among others, and will be making a decision in the near future.

5/23/2025 SPY: -0.67%

Far from one of the worst slides in markets, but directly attributable to the President's truthposting: Therefore, I am recommending a straight 50% Tariff on the European Union, starting on June 1, 2025. There is no Tariff if the product is built or manufactured in the United States. Thank you for your attention to this matter!

Shares of U.S. Steel, however, exploded that day, thanks to Trump’s explicit approval of Nippon Steel’s takeover of said company. This will be a planned partnership between United States Steel and Nippon Steel, which will create at least 70,000 jobs, and add $14 Billion Dollars to the U.S. Economy. Shares soared 21%.

https://truthsocial.com/@realDonaldTrump/posts/114558783827880495 

Apple also fell -3% that day, after The President explicitly threatened a 25% tariff on iPhones not built in the United States. I have long ago informed Tim Cook of Apple that I expect their iPhone’s that will be sold in the United  States of America will be manufactured and built in the United States, not India, or anyplace else. If that is not the case, a Tariff of at least 25% must be paid by Apple to the U.S. Thank your for your attention to this matter!

10/10/2025 SPY: -2.71%

A rather long tirade this time, but once again, a China-US trade war was reignited. The President seemingly canceled a meeting with China’s President and accused China of creating a monopoly of rare earth minerals. But the U.S. has Monopoly positions also, much stronger and more far reaching than China’s. I have just not chosen to use them, there was never a reason for me to do so — UNTIL NOW! Shares of MP Materials, USA Rare Earth, and NioCorp saw significant movement that day as well.

4/8/2026 SPY: +2.51% 

On the same day that The President claimed “a whole civilization will die tonight” the President switched gears, hours later, and announced, after market close, that a ceasefire with Iran had been declared: subject to the Islamic Republic of Iran agreeing to the COMPLETE, IMMEDIATE, and SAFE OPENING of the Strait of Hormuz, I agree to suspend the bombing and attack of Iran for a period of two weeks. This will be a double sided CEASEFIRE! Markets roared back upwards the following day.
