Not seeing a problem here.
"Justice Sam Alito sold at least some of his stock in Anheuser-Busch and bought stock in Molson Coors on Monday, August 14, 2023."
The partnership with Mulvaney and the fake outrage began on April 1st:

On April 6, 2023, the Anheuser-Busch stock price was $66.34.
By June 2nd, it had dropped more than $10 to $54.85.
When Alito sold, it had recovered to $56.30.
By October, it would hit $52.83.
He probably should have held since it's $66.84 as of right now.
But this doesn't appear to be a result of any kind of insider trading or anything. If that were the case, he would have made the trade in early April when the fake outrage was starting.
As long as Anheuser-Busch, or a competitor doesn't have a case before the court, I'm OK with this.
