Stocks bounced on Friday, looking to end the week with a rally, as crude oil spiked and banking stocks recovered after steep declines a day earlier. JPMorgan (JPM) led the Dow Jones Industrial Average higher after CEO Jamie Dimon purchased half a million shares. Deutsche Bank (DB) was also leading the financials sector higher after confirming it will buy back more than $5 billion in senior debt. The repurchase will shore up the bank's financial standing. Jack Dorsey's Square (SQ) jumped after Visa (V) disclosed a new stake of nearly 10%. The new position makes Visa its second-largest shareholder. Groupon (GRPN) surged after beating estimates in its recent quarter. The deals site did swing to a loss, though, on higher promotional spending to ramp up sales.
