Fortinet (NASDAQ: FTNT) - Do Nothing - Q3 FY12/26 Earnings Review

Fortinet’s revenue rose 20% to $2.08 billion, but its 15% Q4 growth guide drove a 25% post-earnings stock drop as product, billings and services growth decelerated.

Great @YetAnotherValue interview with Zack Buckley on Priority Technology $PRTH out today. If you had told me that PRTH would only be up 65% (including massive, unwarranted share-price volatility) from my 5/2024 article after: ° Enormous capital structure improvements (expensive pref was strangling profitability) ° Successful deleveraging ° Solid business execution I would have been very surprised. It is a shame CEO Priore chose a take-private offer rather than capital allocation/return strategy (which I advocated for). Would have been easy enough to stabilize the equity and in my view rocket it higher over time - creating a successful, useful public equity and track record.

Sobering one: of 31 distinct names, only 2 have actually reached my Realistic Valuation target. $EVTL and $RR. Median downside capture on the Sept '25 list: 73% of the decline I forecast. On the 2026 lists: 22-41%. Direction right. Magnitude still pending. This means there is still lots of meat on the bone in many of these names.

What I'm carrying into the next list: → Short arithmetic, not narratives → Overleveraged and Industry Bubble earn their slot → Potential Fraud has to clear a much higher bar → Stop re-shorting $RUM Full table and methodology at Shorts & Squeeze Corner.

Across all 110 position-instances: Average short return: +25.7%Median: +23.1%Hit rate: 81% — 89 of 110 names fell Best call, and it wasn't close: $EVTL Vertical Aerospace $5.00 → $0.58 Top performer on all five lists. The Sept '25 entry is +88%. Even the July '26 entry is +66%. The company flagged going-concern risk in a filing this month.

The rest of the Sept '25 podium — a full year of holding: $EVTL +88% $SMR +77% $LVWR +76% $OKLO +73% $BTQ +73% $SOUN +69% $RGTI +67% 19 of the 20 names on that list fell. Nineteen.

Biggest miss was $RUM. $RUM was my worst pick on four of five lists. Average: -23%. $PLTR: -13% average across four lists. Right on the multiple, wrong on the stock, repeatedly. $CVNA: -4% average — and I had it tagged Potential Fraud.

@BertrandPirel to what do you attribute the substantial availability (1.85m shares) and low borrow cost (3.25%) for $GPRO at IBKR?

Astute observation here. $STLN could not be better situated for the current environment, imo. https://t.co/sy97F9J9YU
