Purchases after results
Not enough history
From Arqit Quantum's own results filings (8-K Item 2.02) and its insiders' Forms 4 and 5. Many companies only let insiders trade in a period after results; OQRO does not know Arqit Quantum's policy and only shows the pattern in the filings. A purchase made long after results, at a company whose insiders usually buy right after them, is marked “Bought outside the usual window”.
Against the S&P 500 over the year
Since Nov 11, 2025, ARQQ is down 53.0% and the index fund is up 10.4%: 63 points behind the market. Traders call a stock that beats the index over a period a relative-strength leader.
