Impressive just how many healthcare companies with no direct or derivative exposure today or at any point to the $MRNA news can rally 10%+ on the day. Be smart for these companies to pocket these gains with secondaries and solidify fragile balance sheets, but in the ultimate short term pump market their management teams will no doubt not want to interrupt their stocks squeeze potential and will not issue shares, but aggressively unload their options

We track insider buying in spinoff or their parents in a custom screen on InsideArbitrage that we like to call the Spinsider. There were three companies (spinoffs or parents of spinoffs) that saw insider buying based on Form 4s filed recently. 1. The home safety and security solutions provider Resideo $RESI completed the spinoff of ADI Global Distribution $ADGI just two weeks ago. This week we saw three different insiders of $RESI buy stock on the open market including the CEO and the General Counsel. $RESI was spun out of Honeywell $HON in 2018, making $ADGI Honeywell's grandchild. 2. Enviri $NVRI was less of a spinoff and more of a breakup. It sold its Clean Earth division to to Veolia Environnement S.A. and paid out $15 per share to shareholders from the proceeds of the sale. It then spun out its Harsco Environmental and Rail divisions and renamed them as Enviri just to confuse us a little. This new Enviri saw insider buying by two insiders including the CEO this week. @valuedontlie especially likes these "stubs" as he likes to call them and has done well with stubs like Starz Entertainment $STRZ Much to my detriment, I kept Lions Gate Studios $LION after the spinoff and sold Starz. 3. The building materials company Amrize $AMRZ, which was spun out of Holcim AG in June 2025 continues to see significant insider buying activity. This month six different insiders including the CFO and the Chief Strategy & M&A Officer purchased shares.

Quite a few directors at Bath & Body Works $BBWI are buying the dip on poor earnings, with the shares dropping to multi-year lows. With negative sentiment pressuring the topline and margins and quite a bit of leverage, we’re not surprised to see this share price action. That said, the company is refocusing on key franchises, improving its product offering, and cutting costs heavily. It's too early to touch this one, but it's certainly interesting to keep on the watchlist on a potential inflection of the fundamentals (while the market continues to puke the shares).
