Dizon Romeo R, Chief Financial Officer of IRIDEX Corporation (IRIX), has filed 76 Form 4 transactions, and the pattern is one-sided. Across all filings, he has purchased $128,003.79 worth of stock in open-market transactions and sold nothing. There are no open-market sales, no sales back to the issuer, and no option exercises in the record. The only non-purchase codes are compensation grants (code A) and shares withheld to cover taxes (code F), both of which are automatic and carry no dollar value as decisions. The buying has been steady and recent. In the last nine months, Dizon has filed 22 open-market purchases, all in IRIX, with the most recent cluster landing in September 2026. On September 16 he bought $4,977 worth, following purchases of $1,530.10 on September 14 and $3,468 on September 10. August brought two buys on the 24th, totaling $4,998.90. The cadence stretches back through June, with six separate purchases between June 3 and June 12, and further back to January and February, where he filed multiple buys each month, including a $7,716.12 purchase on January 23 and a $5,009.46 buy on January 27. The dollar amounts are modest, ranging from roughly $973 to $7,716 per transaction, but the frequency is the standout feature. A CFO accumulating small lots of his own company's stock across 22 separate sessions, with zero sales, is a directional signal in the filing data. The last sale of any kind does not appear in the record, and the most recent activity, the September purchases, continues the pattern.
