Wall Street legend reveals his top AI stock before Oct. 20 (Ad)

Marc Chaikin, the 60-year Wall Street veteran behind the Power Gauge rating system, has flagged a new AI stock ahead of October 20. His system has spotted at least seven of the top 10 performers every year since 2016, including all ten in the 2022 bear market and every member of the Magnificent Seven before their run higher. Now Chaikin's Power Gauge is turning bullish on an under-the-radar company tied to next-generation AI data centers built under Executive Order 14363, technology he says uses 99 percent less electricity and space while offering far greater computing power.tc pixel

Trump's crypto bank just got approved (Ad)

Last month I told investors that a Trump-backed crypto bank could be approved any day. On August 14, it was. Federal regulators granted conditional approval to World Liberty Trust Company… a nationally chartered trust bank tied to the Trump family's crypto venture. Most investors still haven't processed what that means. This bank exists to do one thing. Issue, redeem, custody and back USD1… the stablecoin that has now crossed $4 billion in circulation. The bank isn't operating yet. There are conditions to satisfy first… capital minimums, an audit manager, a sign-off on the business plan. Which means the money hasn't moved yet.tc pixel
