Fetching historical prices and checking every monthly purchase.
The same monthly investment. Three different destinations.
Cash dividends are excluded from all three strategies. These are not dividend-reinvested or total-return results.
Cumulative return = investment gain ÷ total contributions × 100. It is not annualized or time-weighted; dividends are excluded. XIRR measures the annualized return on your dated contributions. TWR removes the effect of deposits. Drawdown is measured on the cash-flow-adjusted TWR index, not account balance.
Each holding’s growth, excluding dividends.
Units and quoted prices are split-adjusted equivalents, not original historical share counts. Value = adjusted units × adjusted close. Existing portfolio weights are never reset.
This is a retrospective simulation of a fixed basket of today’s seven companies. It does not prove that these names could have been identified in advance or that the result will repeat.
This backtest uses final month-end signals. The live Lag7 rule locks its selection one trading session earlier, after the penultimate trading day’s close, so these results are not an exact test of live execution.
XIRR is the annualized money-weighted return using each actual contribution date. It is not ending wealth divided by total deposits and annualized.
Time-weighted return separately links overnight and intraday returns on contribution days. Deposits do not count as investment gains.
Drawdown uses the daily TWR index and includes the initial index peak. It does not capture intraday lows.
Dividend omission: this is price performance only. A dividend-reinvested comparison can produce different outcomes and rankings.
Hindsight universe: today’s Mag7 are held fixed across the entire period. There is no survivorship-free selection process.
Idealized fills: fractional execution at the published opening price is assumed. Historical data precision and revisions can affect near-ties.
Historical split-adjusted prices cover the fixed research period. Downloads include the computed results, monthly selections, purchase ledger, daily values, methodology and calculation code. Raw provider price files are not redistributed.
