Risk & Portfolio

Position sizing

Choosing how much capital or exposure to allocate to a trade or investment.

Plain-English context

Put the definition to work.

ILLUSTRATIVE EXAMPLE

A $250 planned-loss budget and a $3 long stop distance imply 83 whole shares and $249 modeled stop loss, subject to available capital and execution risk.

IMPORTANT DISTINCTION

A planned stop loss is not maximum possible loss; gaps, leverage, costs and capital constraints change the outcome.
