Trump’s EO to send this $5 stock ripping higher…? (Ad)

President Trump's December executive order declared space a national security and economic priority, fueling a race among SpaceX, Blue Origin, and others to build massive satellite constellations. One tiny firm holds the patented tech required to transmit satellite data to Earth at scale - and it reportedly powers SpaceX's most profitable division. Shares trade for under 5 dollars. Former JPMorgan wealth manager Ross Givens says it's the most uniquely positioned stock he's seen in 20 years of trading.tc pixel

Why I'm selling my Snapback Indicator for just $7 (Ad)

For Black Friday, Base Camp Trading's Thomas Wood is offering lifetime access to his proprietary Snapback Indicator for a single $7 payment. Others previously paid $500. The indicator flashes a Crash Alert as a cue to exit or go short, and a Bull Run Alert as a cue to buy or go long. No strings attached, and Wood says there is an unusual reason behind the steep discount.tc pixel
