Why Should You Pay Attention to the 13F Report?
The 13F report is a quarterly holdings disclosure required by the U.S. Securities and Exchange Commission (SEC) from institutional investors with over $100 million in assets. This document covers long positions in stocks, ETFs, options, and more, and is published within 45 days after the end of each quarter.
At first glance, it may seem like a routine regulatory document, but for ordinary investors, it is a window into the movement of top-tier global funds. When Warren Buffett’s Berkshire Hathaway bought TSMC, the stock price surged by 7.6% the next day — this is not a coincidence, but a direct reflection of the influence of large capital.
By tracking changes in these institutions’ holdings, we can identify market hotspots, predict industry trends, and understand shifts in risk appetite. The core value of the 13F report lies in this — it makes the decision-making logic of institutional investors transparent, serving as an important tool for individual investors to learn from and reference.
