Pre-revenue quantum companies fund themselves by issuing stock, so dilution and insider selling are the activity that actually moves these names. This tracker aggregates the last 30 days of SEC filings across all 10 pure-play quantum stocks: open-market insider buys and sells (Form 4) plus new shelf registrations and at-the-market offerings (S-3 / 424B) that signal upcoming dilution.
