Value both choices at the final price
For each price, clamp it to the lower and upper bounds before applying the concentrated-liquidity inventory formulas. Final LP value is final A × final price + final B. Hold value is initial A × final price + initial B. Their difference is final LP value minus hold value; divide by hold value for the percentage gap when hold value is positive. Using one final valuation price makes the alternatives comparable.
Follow a move to the upper boundary
Take hypothetical L = 100 and a range from 1 to 4 B per A. At an initial price of 2.25, inventory is about 16.6667 A and 50 B. At a final price of 4, LP inventory is 0 A and 100 B, worth 100 B. Holding the starting tokens would be worth about 116.6667 B, so the modeled LP value is 16.6667 B lower, approximately 14.29%.
Interpret prices beyond the active range
Above the upper bound, inventory remains all B in this fixed-position model; below the lower bound, it remains all A. Valuation still uses the actual final price, even though inventory calculations use the clamped price. This distinction matters especially below the range, where the all-A balance continues changing value in B. The comparison excludes fees and rebalancing costs and does not estimate how long the position stays outside its range.
