What this market video covers
A stock return and its portfolio contribution are different numbers. Consider a hypothetical portfolio with ten percent in asset A and ninety percent in asset B at the start of one period. There are no cash flows, fees or rebalancing. Asset A gains fifty percent while B loses five percent. A contributes five percentage points to the portfolio return: ten percent weight times fifty percent return. B contributes negative four and a half percentage points. Together the portfolio gains only half a percent. A large winner can be offset by a much larger allocation to a modest loser. Use beginning period value weights and matching total return periods for this calculation. Do not average the two holding returns equally unless the starting allocations were equal. Contributions describe this period, not the next one. Clearly labeled hypothetical worked example; figures are illustrative, not current company results.
