Summary
The article warns against treating delayed 13F filings as live trade signals, using Leopold's heavily analyzed March 31 filing as an example of misinterpretation. The author announces a platform restructuring toward deep research, model baskets, and a living research hub, arguing that context—not raw position data—drives sound investment decisions. For markets, the message is to avoid overreacting to stale portfolio snapshots and to instead focus on fundamental theses and risk management.
-
•Author is restructuring Substack to prioritize deep company research, model baskets, a central coverage document, and a live TradingView research universe over static watchlists.
-
•Leopold's 13F filing from March 31, 2026, is being misread as current positioning, despite being 45+ days old and missing context on timing, hedging, and risk management.
-
•Options positions on 13F are reported as underlying share exposure (e.g., 1 contract = 100 shares), which can inflate the apparent size of put positions relative to actual premium at risk.
-
•Author argues that a 13F snapshot without context—why a position was held, whether it was a hedge or tactical trade—is dangerous to use as a trade signal.
-
•New model baskets will replace static watchlists to better communicate thematic exposure, relative conviction, and portfolio construction across areas like photonics, power, data centers, robotics, and AI infrastructure.
