Direct stock weights are the percentages reported in each SEC filing or issuer holdings disclosure. Cybersecurity weights retain the issuers’ published rounding; totals can differ slightly from 100%, including when cash or other net positions are negative. DRAM exposure is calculated from stock values and swap notionals. Neither is renormalized to 100%. SPY, QQQ, SMH and IBB show long common-stock positions, excluding cash, funds and derivatives. DRAM shows company exposure from shares plus the reported notional amount of long total return swaps, divided by fund net assets. Cash and collateral are not added again. Its gray remainder is 100% minus the displayed company exposures, not a cash balance. Top-10 concentration sums the ten largest company weights, including swap exposure for DRAM. Comparisons match the same stock and share class across funds, including equivalent foreign listing symbols. Snapshot dates differ: read the date for each fund before comparing weights. “Not listed” means absent from the stock positions in that snapshot, not absent today. Ticker labels are matched from the SEC company ticker directory, with issuer holdings used to resolve ambiguous share classes and historical filing symbols retained for companies no longer listed. Company names and weights remain those in the holdings snapshot. This tool uses fixed snapshots and does not yet refresh automatically.
