The Thanksgiving Leftover stocks of 2025 turned in a bad showing during June 2026. The ten worst performing stocks of the S&P 500 (Index: SPX) in 2025 collectively dropped by both measures we use to track their performance.
Our market capitalization-based weighted index of the ten stocks went from holding 92.2% of their value on the day after Thanksgiving 2025 as of 26 May 2026 to 84.6% of that value through the close of trading on 24 June 2026. But that wasn't low as the equal-weighted index, which went from 87.2% to 82.7% of their post-Thanksgiving Day 2025 value as determined by that method.
The S&P 500 was also down month over month, dipping from 109.8% to 107.4%. However, as these values are both over 100%, the index is holding gains, putting its performance on a much better position than that of its ten laggards. The following chart shows how the performance of both the market cap-weighted and equal-weighted Thanksgiving Leftover indices compare with the entire S&P 500 index.
Not all is dismal among the worst performing S&P 500 stocks of 2025. Three, Molina Healthcare (NYSE: MOH), Dow Inc. (NYSE: DOW), and Deckers Outdoor (NYSE: DECK), are outperforming the S&P 500 index, but in the case of Dow, not as strongly as it had been.
The remaining seven Thanksgiving Leftover stocks of 2025 however are doing worse, which can be seen in the next chart:
From here, we'll focus on the stocks of the three firms to see the biggest month-over-month declines:
Dow Inc. (NYSE: DOW). The chemical giant's stock price has risen and fallen in recent months in conjunction with the disruptive impact of the geopolitical event of the Iran war. The firm, which announced a restructuring in January 2026, benefited from the event's effect upon its international competition, sharply boosting its profits while trade from the region was affected by the conflict. But that benefit has increasingly dissipated as the ceasefire reached in late March 2026 has held, which benefits Dow's biggest international competitors as they recover from the disruption. The company is now facing a delayed market evaluation of the effectiveness of its restructuring.
The Trade Desk (Nasdaq: TTD) continues to find new ways to disappoint investors with its prospects for a turnaround still in doubt. The outlook of the company's core digital advertising business continues to be hammered as the disruption from AI technologies makes it increasingly vulnerable to competition. At the same time, The Trade Desk has also endured management turmoil and in June 2026, welcomed its third CFO since the beginning of the year.
Keep in mind that The Trade Desk's stock has been doing badly since the end of 2024. Its stock price fell by 66.3% by Thanksgiving 2025 to earn its place on the list of 2025's Thanksgiving Leftover stocks. Since Thanksgiving 2025, The Trade Desk's stock price has gone on to lose 55.3% of that already much reduced value.
Lululemon Athletica (Nasdaq: LULU) is another Thanksgiving Leftover stock facing stronger competition while undergoing extreme management turmoil. Here, the battle between the company's board of directors and its founder Chip Wilson have reached a truce, with the now-outsider Wilson successfully getting his two candidates on the board, which he can use to change the company's direction. Unfortunately, there's a lot of opportunity for improvement as the company's product lines failed to generate either positive sales growth or earnings in its North American markets.
Running struggling businesses like these is not easy. Turning around a struggling business is likewise hard, but there is a lot of potential value that can be realized if it can be successfully done. The trick for investors considering these stocks as potential turnaround stories is to sort the proverbial wheat from the chaff. Our sense from sampling of companies we highlighted in this edition is that that some 2025's Thanksgiving Leftover stocks might qualify as positive turnaround stories, but are taking an excessive amount of time to get themselves properly sorted out. It's no wonder those companies have continued losing substantial value in 2026, dragging down the market-cap and equal-weighted groups as a whole.
