I dug into the Alt5 saga for CNBC. In August, the elder Trump brothers celebrated a deal that saw the family earn a half-billion dollars. On the other side of that deal was a little-known stock, then called Alt5 Sigma. It has turned out very poorly for Alt5's investors, who have taken 93% losses.
Eric Trump and Donald Trump Jr. celebrated a deal with Alt5 Sigma that generated roughly $500 million for the Trump family. The company's shares are down 93%.
