In 1969, Warren Buffett retired from managing money and dissolved his partnership, shifting his focus more towards Berkshire Hathaway. This decision occurred during a period of significant economic change marked by the onset of "stagflation" and sharp drawdowns for "high-flying go-go stocks", as Buffett found the investing environment increasingly "negative and frustrating" and struggled to find new opportunities that aligned with his investment style. Throughout his partnership, Buffett consistently followed fundamentalist investment principles, focusing on basic value, a margin of safety, and avoiding "glamour stocks" or "concept companies," a disciplined approach that contrasted sharply with the speculative market of the late 1960s.
