Short answer
A full rebalance treats the target as something you should reach immediately. A partial rebalance treats the target as a direction and moves only part of the way, leaving the rest for later if the signal still holds.

What to remember
- Lower spread crossing and slippage
- Less sensitivity to tiny target revisions
- A smoother path when several sleeves compete for capital
Why people choose partial moves
Partial rebalances are often a response to cost or noise. If the target itself is not stable enough to deserve a full turnover event every time it moves, then moving halfway can preserve more of the edge than forcing the portfolio to chase every update.

What to validate
Test whether the slower adjustment is still fast enough for the edge you are trying to express. A partial rule that looks cost-efficient can still become under-responsive if the opportunity decays quickly after the signal changes.
