$Digital World Acquisition Corp (DWAC.US)$, the SPAC that recently agreed to combine with Donald Trump's Trump Media and Technology Group, soars more than nine-fold to take the top spot among the week's five biggest financial gainers (with market cap over $2B) by a wide margin.
By contrast, the second-biggest increase for the week, normally an impressive rise, looks less stellar — $Athene (ATH.US)$, +19%, after its parent $Apollo Global Management (APO.US)$ laid out its plan for 18% CAGR for fee-related earnings through 2026 during its investor day.
Apollo Global, as the third biggest gainer, rose almost as much at 18%;
Pet health insurer $Trupanion (TRUP.US)$ gains 18%;
$Qifu Technology (QFIN.US)$, +13%, partly recovers from the Chinese fintech slump triggered by Beijing's new data privacy law.
Among the stocks falling the most for the week, $Upstart (UPST.US)$ declined the most, down 12%, after the stock received a double-downgrade at BofA Securities on the basis that the stock's near-term upside is already priced in.
Brazilian bank, Banco Santander (Brasil) follows, -11%;
$PayPal (PYPL.US)$ dropped 10% during the week after reports that it's in talks to buy Pinterest for ~$45B, mostly in stock;
$OneMain (OMF.US)$, -9.1%, reported Q3 earnings beat estimates, but revenue was in-line; and
Crypto-focused $Silvergate Capital (SI.US)$, which reported better-than-expected Q3 earnings, saw its stock slip 8.5% during the week.
