Option News Today — August 13, 2026

The stock market continues to show signs of resilience, with the latest rally breathing new life into equities and even sparking a notable comeback in South Korea's Kospi index. However, this renewed enthusiasm for stocks has not been universally shared, with the credit market expressing some concern about the implications of the rally. Meanwhile, individual companies are making headlines with strategic plans and product launches, such as Ford's increased production plans for its Lincoln brand and Chili's successful foray into the chicken-sandwich market.

Beyond these corporate developments, investors are also reacting to earnings reports, with Cerebras stock experiencing a significant decline after its second earnings report since going public. On a separate note, consumers can look forward to increased benefits from Social Security next year, as recipients are set to receive a cost-of-living adjustment. As market participants navigate these varied signals, they will be watching to see how the current bull market in equities, including the one in South Korea, sustains itself over time.
