Exit Summary
Entry $9.36Exit ~$20.00Exited Feb 2026

We sold the last of our SGML around $20, turning a nice profit on shares we'd purchased when the stock got taken to the woodshed. This was always more of an “I think this has just gone too low” trade, and its rapid move higher – coupled with our somewhat superficial knowledge of the asset – made us weak-handed. This horse goes to the hobby farm for now, but if lithium gets really hot down the road, we know where to find it.

Focusing on Value in Volatile Times

I sold the last bit of my SGML around $20, turning a nice profit on the shares that I'd purchased when the stock got taken to the woodshed when lithium was hated. I have little more to say about SGML, but this is a name that I would look at again if lithium gets really hot somewhere down the road. This horse goes to the hobby farm for now.

Full Throttle, Empty Tank

SGML ripped into the low $20's and I sold more stock. I've sold 90% of my position now, for a very nice win in a short time period. This was always more of a "I think this has just gone too low" trade for me and its rapid move higher, coupled with my somewhat superficial knowledge of the asset, made me weak-handed. I never forget a stock, so I'll keep an eye on it.

The Art of Doing Nothing

This ran all the way to over $16 on no news so I did lock in some profits, but I still own 40% of my position as industry watchers get more constructive on lithium prices going forward – suggesting that the bottom might be in. Industry bellwether Albemarle (ALB.US) keeps making new 52-week highs and lithium demand just keeps rising.

This is the best producing asset in the hands of an independent in my universe and it has impressive capital efficiencies.

This is my only lithium exposure. In reflecting on the pullback in the stock from its highs, it may be because a recent news article out of Brazil highlighted some critical comments from the company's former CEO in terms of how the current team is running the mine, but the company's responses in the article dismissed the concerns. I'm not as close to this one as I am to other stories, so I can't comment on the back-and-forth in that article, but the scale and quality of the asset – as well as its leverage to lithium prices – are undisputed, so I remain long a partial position and will keep an eye on the $11–12 range as a support level for the stock.

Building a Stable

SGML dipped into the $6-range for a nanosecond and is now $11 as I type this on optimism that the lithium price is headed higher. The whole sector is up, but SGML is up a lot as I write this, some 30% on the day. While its up nicely from the lows, it's still a very attractive asset to larger players and sits at the lower end of the global cost curve, with very attractive capital efficiencies on production expansion. As one of the largest independents out there, this could be swallowed up by a larger player at any time. The demand for lithium and batteries isn't going away, so SGML may be attractive to a large player looking to boost their production immediately at a low cost.

Beginnings

I'm of the view that the long-term lithium demand story is a good one. There are batteries in everything these days and low-cost producers will ride out the kinds of lithium price lows that hamper production and eventually lead to higher prices. I have no specific insight to offer when it comes to SGML, but this is a large-scale, low-cost, low-capital-intensity, scaleable, high quality asset in Brazil that is one of the larger projects in the hands of an independent producer. Since bottoming in June, the stock has been making higher highs and higher lows with indications of accumulation underway from technical chart indicators like on-balance-volume. After a long fall from its 2022 highs, industry bellwether Albemarle (ALB.US) has nearly doubled since April and when you're looking for sector sentiment-may-be-turning indicators, keeping an eye on the bellwethers is a good idea. It's a bit of a loose buy for me, but I've added stock around current levels and, all else being equal, I would add more at the lows around $6 if the stock pulled back that far on a broader market dip.
