The portion of my brain that’s dedicated to our weekly missives to the Irregulars is on standby, waiting to see if there’s anything of interest to share with you on Monday and Tuesday of next week during the Value Investing Congress in Las Vegas (if you’ve shelled out your $4,500 to be at the Congress too, drop me an email — The least I can do is buy you a drink).
