For many Wall Street investors, it is their first time navigating market uncertainty at a time of geopolitical upheaval. In these testing weeks, we are going to take a look at Ken Fisher’s moves, the billionaire chief of Fisher Investments. Fisher has owned his investment firm since 1979, starting with $250 and expanding it into one of the biggest in the world. At the end of the fourth quarter of 2025, the value of the 13F portfolio of his fund alone was close to $300 billion.
During a recent appearance on Fox Business, Fisher urged for calm amid rising concerns over oil prices and supply disruptions, noting that geopolitical conflicts involving oil-producing regions typically trigger an immediate spike in oil prices because markets fear severe supply disruptions, but those fears are usually exaggerated and prices tend to fall once it becomes clear that supply continues to flow and global producers adjust.

Fisher also appeared on his channel on YouTube earlier this month to tackle questions about the broader economy. During his discussion, he characterized the present market as a “low-hire, low-fire” environment, meaning companies are cautious about both hiring and layoffs. He argued that layoff headlines could be misleading because “every time there’s layoffs of any type, the media makes much of it,” even though the numbers are small relative to the total workforce. Fisher noted that layoffs like “10,000 people here, 5,000 people there… is not enough to put a dent into this market because it’s so huge,” and added that many displaced workers quickly find new jobs because “the kind of people they lay off are very employable.” As a result, he said the real indicator to watch wasn’t isolated layoffs but broader unemployment trends, explaining that “we’re not seeing… unemployment going up,” and that the labor market would only truly weaken if “you start to see the labor market loosening… increased unemployment.”
