Sixth Street Specialty Lending heads into its Q1 2026 earnings print with a striking insider buying cluster as the most telling signal in the setup.
Between late February and early March, a wave of insider purchases totalled over $10.8 million in net value across 90 days. Alan Waxman, a Vice President, alone bought 545,000 shares across four separate transactions in early March, paying between $18.18 and $18.47 per share. Several other insiders joined the buying: a fellow Vice President, an Independent Director, and the Deputy CFO all added shares during the same window. The stock has since recovered to $19.60, roughly 6% above those purchase prices, giving the cluster a meaningful mark-to-market gain heading into the print.
The borrow market adds texture to the setup. Cost to borrow has been running at an elevated 16.2% — high for a BDC — after spiking above 24% in late April before easing back. Short interest has held essentially flat around 8.2 million shares over the past month, with only modest week-on-week declines. The lending pool remains tight: availability has swung between fully constrained and around 16% through April, suggesting meaningful demand for borrow without a clear directional squeeze. The ORTEX short score of 78.8 — near the top of its recent range — reflects that the stock remains closely watched by short sellers despite the flat SI trend.
Options positioning is the one signal that diverges from the cautious borrow picture. The put/call ratio has drifted below its 20-day average, sitting at 0.59 against a mean near 0.64. That's modestly call-heavy — the least defensive reading in the recent window — and contrasts with the elevated cost to borrow. The prior Q1 print, reported in February, saw the stock fall more than 6% on the day and nearly 10% over the following week, which gives some context to why the borrow market remains active even as options traders lean toward calls.
The analyst debate centres on credit quality and rate sensitivity. Bulls point to Sixth Street's track record of generating excess returns during periods of dislocation, its strong positioning in complex middle-market deals, and what they see as sufficient excess capital. Bears flag the BDC's heavy software-sector exposure, rising competition, and the lingering uncertainty around credit markets as rates shift. On balance, the Street has been trimming targets — JP Morgan and RBC both cut in recent months, though nearly all maintained positive ratings — arriving at a consensus target around $23.75 against a current price of $19.60. The gap implies meaningful upside if the credit portfolio holds up, but analysts have been moving cautiously in one direction.
The Q1 print is therefore a test of whether the February print was an outlier — or whether the portfolio-level credit dynamics that spooked markets then have stabilised enough to justify the insider conviction that accumulated through early March.
