Missing the best days
Holding throughout, against being absent for the largest single-day gains
—
How this is calculated
Daily returns are split-adjusted, then the largest single-day gains are removed and the remainder compounded. A day the stock did not trade counts as a flat day and cannot be selected. This is arithmetic on the historical series, not a claim about any strategy: nobody could have known in advance which days these were, in either direction.
The heaviest horizontal line on the chart marks the amount originally invested.
