July 15 (Reuters) - Crypto stocks, prison operators and other shares that could benefit from a Donald Trump presidency jumped premarket on Monday as an assassination attempt on the Republican candidate boosted odds of his victory in the U.S. elections.
Investors said trades betting on Trump's victory will increase this week after he was shot in the ear during the rally in Pennsylvania. The former U.S. president pumped his fist moments after the attack and his campaign said he was fine.
Shares of Trump Media & Technology Group (TMTG) soared 46%. Trump owns a majority stake in the company, worth about $3.8 billion as of June 25 according to LSEG data, and it is the parent of social media platform Truth Social.
TMTG stock has surged 75% this year, driven by retail traders betting on a Trump victory at the Nov. 5 rematch against Democratic candidate and U.S. President Joe Biden.
Crypto stocks also got a boost, tracking bitcoin's jump to a two-week high, as Trump has presented himself as a champion of cryptocurrency. Crypto exchange Coinbase Global , bitcoin miners Riot Platforms Inc and Marathon Digital added between 5% and 7%.
"Investors are becoming more confident of a Trump victory, and it is starting to be more heavily reflected in certain sectors," said Rick Meckler, partner at Cherry Lane Investments, but added that the impact on the overall market was more muted.
"Most investors are not changing their overall commitment to U.S. equities. After all, the broad stock market rose under the last Trump administration and has risen under the Biden administration as well."
Futures tied to the S&P 500 edged 0.5% higher.
Gun makers and ammunition stocks Smith & Wesson Brands , Sturm Ruger & Company and Ammo jumped between 5% and 6.7%. Gun stocks tend to rise after a mass shooting as calls for gun control in the past have led some people to buy more firearms out of fear that their availability would be limited.
Prison stocks Geo Group and CoreCivic also rose 6.8% and 7.8%, respectively. Both are potential beneficiaries of a Trump presidency as he has promised to crack down on illegal immigration, which could boost demand for detention centers.
Software developer Phunware, hired by Trump's 2020 presidential re-election campaign to build a phone app, jumped 30%, while video-sharing platform Rumble, popular with conservatives, added 9%.
On the downside, clean energy stocks slipped as Trump has said he would reverse many of the Biden administration's signature climate policies, including tax incentives, if he wins the election.
Invesco Solar ETF fell 4.3% and iShares Global Clean Energy ETF fell 3%.
U.S. voters view Trump as the better candidate for the economy, according to Reuters/Ipsos polls, even as Biden's White House seeks to benefit from a solid economy with inflation slowing and low unemployment.
"It is fair to assume that any bump in Trump's approval rating stemming from this event could dissipate between now and election day, but we believe Trump's defiance following the attack could be the defining image of this election cycle," said Isaac Boltansky, director of policy research at BTIG.
