Michael Bur just sold one of his favorite stocks and he fully plans to buy it right back. This isn't panic. It's not a downgrade. It's taxes. On Monday, Bur laid out his fourth quarter playbook on his Substack, Cassandra Unchained, and it reads like a master class in one of Wall Street's oldest year-end rituals, tax loss harvesting.
I'm going to walk you through every move he described, the 30-day trick at the center of it, and why the calendar itself might be the real strategy here. Here's the headline trade. Bur sold his Lululemon position, a stock he has called a multi-year hold, now down 55% this year, and immediately bought Decker's Outdoor, the company behind Hoka and Ugg, as a standin.
He expects the two beaten down apparel names to move together for 30 days. Then once the window clears, he buys Lululemon back. Same conviction, better tax bill. So what is tax loss harvesting exactly? Every fourth quarter, investors sitting on big winners elsewhere in their portfolios go hunting for losers to sell.
A realized loss offsets realized gains, which means a smaller tax bill come April. The selling pressure is so predictable it has a season and it routinely pushes already beaten down stocks even lower into year end which is exactly when value investors like Bur start circling. But there's a catch and it's the whole reason this story is interesting.
The IRS wash sale rule says if you sell a stock at a loss and you buy the same or what the IRS calls a substantially identical security within 30 days before or after the sale, the loss is disallowed. No tax benefit. The rule exists to stop people from faking losses on paper while keeping their position.
Buy it back on day 29 and you've harvested nothing. So professionals run the swap. Sell Lululemon, buy something similar but legally distinct, Deckers, another beaten down apparel name in the same sector and hold it for 30 days. You keep your exposure to the theme. You bank the tax loss and then you rotate back into your original conviction.
It's completely legal. It's standard practice among professionals and almost nobody outside the industry ever talks about it. That 30-day holding period is the entire game. Bur ran the same playbook on a much bigger stage, the mortgage giants. According to the writeup, he liquidated his entire Fanny May position and consolidated everything into Freddy Mack.
Same sector, same bet on housing finance reform, but a different security. So, the harvested loss counts. and he says he plans to run the trade in reverse next month, rotating back once his own 30-day clock clears. Why does he care about staying in the trade at all instead of just sitting in cash? Because he's watching Washington.
Bur believes a decision on the senior preferred shares could be coming and he thinks a favorable ruling could trigger a violent squeeze on short sellers. He doesn't want to be sitting on the sidelines in cash when that headline lands. The swap lets him harvest the loss without losing his seat. Not every position got the swap treatment.
Take Fiserve, the payments company. Bur says he's simply holding. He admits his entry price was too high relative to his own valuation models. But at today's price, he sees low teens annualized returns over the long run. And critically, there's no clean proxy to swap into, no twin stock, no trade. So he sits and waits and does nothing, which in his world is also a decision.
Then there's the options engineering, and this is where it gets elegant. After Sprouts Farmers Market and Zoitas both touched new lows, Bur didn't buy more stock. He replaced his equity positions with far out of the money LEAP calls expiring in 2028 and 2029. Think of a LEAP as a longdated lottery ticket with a thesis.
You get the same upside exposure as owning the stock for a fraction of the capital at risk. If he's wrong, the loss is capped at the premium he paid. If he's right, the leverage is enormous. On the other side of the ledger, protection. Bur bought long-dated out-of-the-oney put options on MetLife expiring in 2029.
His stated reason is worth hearing carefully. He says he's seeing stress signals building in private credit and private equity valuations. Those are the corners of the financial system where losses hide the longest because nothing has to mark to market until it blows up. A cheap longdated put is his way of getting paid if he's right about the rot.
And then there's China, the biggest new bet in the whole update. Bur established what he describes as a sizable position in BYD, the electric vehicle maker, after a pullback in the shares. He also bought far out of the money 2029 call options on JD.com. His framing, Hong Kong listed equities are sitting in a historically prolonged bare market, but the underlying businesses are still generating real cash, deep value.
In other words, Bur's native habitat. But noticed the Chinese giant that didn't make the cut, Alibaba. Bur flipped his entire Alibaba position into JD months ago, and he says he's not flipping back. His words, Alibaba would have to fall by half before he'd look at it again. The reason is delusion. The company is issuing billions in new shares to fund its AI infrastructure buildout, and Bur refuses to bless a company printing stock to chase a capeex race.
He'll watch the AI story from the sidelines in JD, not Alibaba. Zoom out and there's a bigger macro call underneath all of these moves. Bur is positioning, in his words, for an early end to the AI boom and a revival in value stocks reminiscent of 2000 to 2003 when the cheapest, most hated parts of the market came roaring back.
Every trade in this update, the harvested losses, the proxies, the longdated options, the Chinese value bets, is a piece of that same puzzle. Buy what's despised, hedge what's euphoric, and let the calendar do the rest. Here's the line I want you to remember. Bur has said this is his favorite time of year.
Quote, "A great time to find great companies being sold down too far as a result of window dressing and tax loss harvesting." Translation: Your tax bill is someone else's buying opportunity. Every December, the market holds a clearance sale on its biggest losers, and the professionals show up with a shopping list while everyone else is showing up with losses.
A few honest caveats before anyone does anything with this. One, these are Bur's stated positions from his Substack writeup. They may have changed already, and I can't see his brokerage account. Two, a proxy is not the same stock. Deckers can diverge from Lululemon during those 30 days and the swap can backfire.
Three, tax rules are complicated, personal, and jurisdiction specific. I am not a tax professional. This is not tax advice. Talk to one before you harvest anything. The real lesson here isn't which tickers Bur bought. It's that the best investors don't just pick stocks. They manage taxes, timing, and the calendar with the same care they give to valuation.
the wash sale window, the fourth quarter harvest, the proxy swap. These are tools and they're available to anyone patient enough to learn them. Educational only, not financial advice and not tax advice. If you learn something, subscribe. I'll see you at the next one.
