Notes

  • Prices, exposures, gains, returns, and weights are shown as of the record date and may not reflect current market prices.
  • Colored markers distinguish long and short positions; negative share counts represent short or synthetic short exposures.
  • Cash is generally held in money market funds. Additional liquidity, when needed, is obtained through box spread loans.
  • Average cost is the running average of the trade log across all accounts and can differ slightly from the cost a broker shows.
  • Shares and prices are adjusted for later splits to today's share basis, matching the trade log, so they may differ from how the statement of the time showed them.
  • A synthetic short (a short call and a long put at the same strike) is recorded as the stock it stands in for; single-leg options are not recorded.
