Rent out your stocks? (Ad)

If you owned a rental house, you would collect rent while you waited for it to rise in value. A covered call lets you do something similar with stocks you already own. Own at least 100 shares and you can get paid cash today for agreeing to sell them at a higher price later. That cash is yours to keep no matter what happens next.

Elon says the ‘S’ word (Ad)

Elon Musk and Sam Altman have sued each other and feuded for years. Yet within days of one another, both men described the same moment in strikingly similar terms: a technological tipping point they call the Singularity. James Altucher says the idea once belonged to science fiction. Now he connects it to a move Musk could make as soon as October 21, and lays out what both men see coming in a short presentation.tc pixel
