Stock futures retreated in premarket trading Thursday as a fresh wave of geopolitical anxiety rattled Wall Street. While investors had begun pricing in an end to the month-long conflict, crude oil prices surged over 7% following President Donald Trump’s latest warning to hit Iran "extremely hard."

Here are some of Thursday's biggest stock movers:

BIGGEST STOCK GAINERS

* READY CAPITAL (RC [https://seekingalpha.com/symbol/RC]) +4% – Shares advanced after the company outlined progress on its deleveraging strategy, including the sale of 47 commercial real estate loans totaling $943M in unpaid principal balance and the collapse of its remaining CLOs. The company also issued a redemption notice for its 6.20% notes due July 2026 and entered into a $1B off-balance sheet arrangement to fund new CRE loan originations. The actions are aimed at boosting liquidity, reducing legacy exposure, and strengthening the balance sheet.
* STITCH FIX (SFIX [https://seekingalpha.com/symbol/SFIX]) +3% – Shares rose after the company resumed share repurchases under its existing $150M program. Stitch Fix bought back ~4.5M shares for $15M between mid-March and early April, with ~$105M still available for future buybacks. The company noted repurchases may continue through open market transactions, private deals, or Rule 10b5-1 plans at its discretion.

BIGGEST STOCK LOSERS

* CELLDEX THERAPEUTICS (CLDX [https://seekingalpha.com/symbol/CLDX]) -7% - Shares slipped after the company priced an underwritten public offering of ~10.3M shares at $29 each, raising about $300M in gross proceeds. The offering includes a 30-day option for underwriters to purchase additional shares. Proceeds will primarily support commercial readiness for barzolvolimab, pending approval, along with pipeline development and general corporate purposes.
