Inside the Multi-Class Trap: How Form 4 Table I Misleads About Insider Ownership

The "Zero Share" Mystery: Why Reading Form 4 Table I Isn’t Enough

For many retail investors, the SEC’s Form 4 is the holy grail of insider sentiment. A large "S" (sale) transaction followed by a zero in the "shares owned after" column often triggers immediate bearish speculation. "The CEO has exited fully!" scream the headlines. But in the world of high-growth technology and founder-led companies, a zero on Table I is often just the tip of the iceberg. To truly understand an insider’s conviction, you must escape the "Multi-Class Trap" and dive into the data that lives on Table II.

What is Table I? The Class A Mirage

Table I of a Form 4 filing reports transactions and ownership of non-derivative securities. In most modern tech companies, this typically refers to Class A common stock—the shares that are publicly traded on exchanges like the NASDAQ or NYSE. When an insider sells their Class A shares, Table I will accurately show the balance dropping to zero. However, Class A shares are often only a fraction of an executive’s total economic exposure.

What is Table II? Where the Real Stake Lives

Table II is where the SEC requires insiders to report derivative securities. This includes stock options, warrants, and, most importantly, Class B or Class C units that are convertible into Class A shares. Many founders maintain their voting control and the bulk of their wealth through these higher-vote share classes. At 13F Insight, we frequently see filings where an insider’s Table I balance is zero, but their Table II balance shows millions of shares held via trusts or holding companies. Track these nuances on our insider signal dashboard.

The Multi-Class Case Study: CoreWeave and Beyond

Consider a recent example from the AI infrastructure sector. Brannin McBee, CDO of CoreWeave (CRWV), recently reported sales that left his Table I balance at zero. To an untrained eye, it looked like a complete exit. But our data revealed that he retained over 6.9 million shares through Table II derivative securities. Without cross-checking both tables, an investor would have missed 95% of his actual stake. You can see similar patterns in companies like Datadog and Boston Beer.

The 13D/G Cross-Check: The Third Layer of Defense

While Form 4 Table II is critical, the ultimate source of truth for major stakes is often the Schedule 13D or 13G filing. These filings are required for anyone (including insiders) who owns more than 5% of a company’s shares. Even if an insider’s Form 4 is confusing, the 13D/G will report their beneficial ownership, which includes all shares they have the power to vote or sell. Combining 13D data with Form 4 activity is the gold standard for institutional-grade analysis. Check our filer profiles for these >5% stake details.

Three Rules for Smarter Insider Analysis

1. Never trust a zero on Table I. Always scroll down to Table II to see if the insider holds Class B shares or unexercised options.
2. Check the footnotes. Many Form 4 filings include critical context in the small print, such as whether a sale was part of a pre-planned 10b5-1 program.
3. Verify with 13D/G filings. If an executive is a founder or a >10% owner, their "total beneficial ownership" reported in 13D/G filings is the most reliable anchor.

Conclusion: Precision Pays

In the high-stakes world of institutional investing, precision matters. By understanding the difference between Table I and Table II, you can avoid the common retail mistakes that lead to overreacting to routine executive liquidity.
