According to Brad Freeman (@StockMarketNerd), traders should exercise caution when reacting to 13F filings, as the reported trades may be several weeks old and positions could already be closed (source: Twitter). Freeman notes that while the 13F season can provide valuable inspiration and new trading ideas, it should not be used as a direct trading signal. For crypto market participants, this highlights the risk of lagging information affecting both traditional equities and crypto-linked stocks, emphasizing the need for real-time data and independent analysis when making trading decisions.
