Questions people ask
Why is a 20% loss not undone by a 20% gain?
The gain is measured against the smaller balance left after the loss, so it recovers less than it appears to.
Limitations
Every result here is arithmetic on the numbers you enter. It carries no view on any specific security, assumes returns are steady when real returns are not, and ignores taxes, slippage and commissions. Use it to size and sanity-check, not to forecast.
