Share Trading comparison
CMC Invest vs CommSec
CMC Invest and CommSec are both CHESS-sponsored, fee-free-to-hold brokers, but they serve very different investors. CMC Invest lets you buy up to $1,000 of ASX stock per security per day for $0 brokerage — a game-changer for dollar-cost averaging. CommSec, owned by Commonwealth Bank, charges as little as $5 per trade (with a CDIA account) and offers a more full-service experience, including US fractional shares and after-hours trading.

| Corporate action fees | — | Corporate actions (SPP, rights issue, takeovers, demergers, dividend payments) are not separately charged by CommSec. They are processed via the share registry/issuer. CommSec does not send trade confirmations for off-market events, so Sharesight/other tracker sync requires manual updates. Failed-settlement fees apply if payment is late ($10 minimum or 0.66% above $1,500). |
