Simplex Trading has submitted its quarterly Form 13F to the U.S. Securities and Exchange Commission, providing a detailed snapshot of its equity holdings as of the most recent quarter.

Live News
Simplex Trading, a well-known proprietary trading firm and market maker, filed its Form 13F with the SEC on May 14, 2026. The quarterly report discloses the firm’s long positions in U.S. equities, options, and convertible securities as of March 31, 2026—the end of the latest completed quarter. While the specific holdings were not immediately detailed in the public filing summary, the submission is part of the routine disclosure requirements for institutional investment managers with at least $100 million in assets under management.
The 13F filing is closely watched by analysts and retail investors because it reveals the trading activities of large money managers. Simplex Trading, which is primarily known for its high-frequency trading and options strategies, may hold a diverse portfolio spanning technology, finance, and consumer sectors. However, the firm’s recent filing does not specify whether its holdings have increased or decreased in size, nor does it indicate any particular stock additions or reductions.
The SEC mandates that such filings be made within 45 days of the end of each quarter, meaning the March 31 deadline corresponds to the May 14 submission. This filing marks the most recent public look into Simplex Trading’s investment positions.

Expert Insights
From an investment perspective, the Form 13F filing by Simplex Trading provides a delayed, yet informative, view of institutional positioning. Market participants often use these disclosures to gauge the confidence of large capital pools, though the data’s lag—up to 45 days—means that the actual portfolio may have shifted significantly since the filing date.
“While 13F filings can offer valuable clues, they should not be used as a sole basis for trading decisions,” notes a compliance analyst familiar with regulatory disclosures. “Simplex Trading, in particular, operates a complex book that includes frequent hedging adjustments, so the snapshot may not fully capture its current risk exposure.”
Investors might look for concentration in sectors like technology or healthcare if the full filing shows significant weight. However, because the report is historical and lacks detail on short positions or derivatives, it paints an incomplete picture. The market reaction to such filings tends to be muted unless they reveal a dramatic change from the prior quarter.
Overall, the filing underscores the ongoing transparency in U.S. markets but reminds participants that institutional strategies evolve rapidly. Cautious interpretation would involve combining the 13F data with other real-time indicators such as trading volume and options flow.
