The total dollar amount of an insider transaction, calculated as Shares multiplied by Price.
Definition
In insider-transaction analysis, nominal value is the reported or calculated gross dollar value of a row, commonly Shares multiplied by Price. It is a derived comparison field rather than an SEC-defined measure of conviction or profit.
Nominal value converts share counts into dollars so insider trades can be compared across companies with very different stock prices.
Why Share Count Alone Misleads
A 10,000-share purchase can mean very different things depending on the stock price. Ten thousand shares of a $5 stock is a $50,000 transaction; ten thousand shares of a $500 stock is a $5 million transaction.
Nominal value normalizes these trades into dollars, making it possible to compare insider conviction across tickers, sectors, and market caps.
How Nominal Value Feeds Net Flow
InsiderAlpha computes nominal value from shares multiplied by transaction price, then aggregates open-market buys and sells. This is the foundation of net capital flow.
The limitation is that nominal value should still be interpreted relative to insider wealth, remaining ownership, company size, and normal compensation schedule.
Data Validation Rules
Use Shares × Price only when both fields are valid for the economic event. Preserve reported Total_Value and calculated calculated_total_value separately, record rounding differences, and flag missing, zero, or non-cash prices.
Weighted-average prices summarize multiple executions. Code F prices can be valuation conventions; Code A can use zero or no price; derivative exercise value differs from market purchase value. Nominal value therefore requires transaction-code context.
Common Analytical Errors
Error 1: calling every price exact. Many are weighted averages.
Error 2: treating zero price as zero economic value. Grants and gifts can have no transaction price.
Error 3: using all nominal values in net flow. Only eligible P and S rows enter the defined metric.
Nominal Value Examples
| Shares | Price | Nominal Value |
|---|---|---|
| 5,000 | $20 | $100,000 calculated nominal value; context determines materiality. |
| 5,000 | $200 | $1,000,000 calculated nominal value; still requires code and holdings context. |
| 50,000 | $200 | $10,000,000 calculated nominal value; plan and transaction context remain necessary. |

Why it matters for Whale Tracking
Tracking shares alone is misleading because a 10,000 share purchase of a $2 stock is vastly different from a 10,000 share purchase of a $500 stock. Nominal value normalizes the data into standard USD, allowing for accurate comparison between different companies and executives.
Technical Nuance
Price can be missing, zero, a weighted average, a valuation for withholding, or economically different for a derivative transaction. `Total_Value` and `calculated_total_value` require validation and should not silently substitute for cash paid or proceeds received.

Real-World Example
"A 5,000-share Code P row at $200 has calculated nominal value of $1,000,000. A 5,000-share Code A award at a reported zero price should not be treated as a zero-economic-value market purchase."
