What this market video covers
A stock split should not create a fake market loss in a price weighted index. Consider a hypothetical two stock index. The prices are one hundred dollars and fifty dollars. With a divisor of two, the index level is seventy five. The first stock has a two for one split, cutting its price to fifty dollars with no economic price move. The new price sum is one hundred dollars. Keeping the old divisor would falsely show an index level of fifty. Instead, set the new divisor to one hundred divided by seventy five, or four thirds. The level stays seventy five. The adjustment preserves continuity at the split. It does not preserve the stocks relative price weights for future moves. This is a toy price weighted example, not the S and P five hundred, which uses float adjusted market capitalization. Clearly labeled hypothetical worked example; figures are illustrative, not current company results. Educational content, not personalized investment advice.
