Continuous Value Interpolation in Multi Asset Allocation Models
Continuous value interpolation maps asset valuations onto a smooth allocation scalar field, converting discrete rebalancing jumps into friction-minimized paths.
non-linear liquidity
Meaning
Market conditions dictate that the cost of executing a position does not scale in direct proportion to the volume exchanged. In environments with non-linear liquidity, a trade of double the size might cost four times as much in price impact. This phenomenon occurs because the order book has finite depth, and large orders must eat through multiple levels of pricing to be filled.
The measurement of this curve is essential for understanding the true cost of moving capital. A founder tracking value must account for this drag to avoid overestimating the net worth of an illiquid stake.
Execution Penalty
Slippage increases as the trade size approaches the limits of the available float. This non-linear liquidity creates a ceiling on the size of an efficient transaction. Beyond a certain point, the cost of the trade destroys the expected value of the move.
A practitioner must calculate the optimal batch size to minimize the total penalty over a series of actions.
Market Depth
Thinly traded assets exhibit the most dramatic curves. In these cases, even a moderate attempt to liquidate a position can cause a price collapse. The shape of the liquidity curve provides a signal of how fragile a valuation might be.
A high paper value means little if the act of realizing it causes the value to vanish.
Volume Threshold
Stability exists only within a specific range of activity. Below the threshold, the market absorbs trades with little friction. Once non-linear liquidity takes over, the system enters a regime of high friction.
Identifying this boundary allows for the planning of exits or entries that stay within the efficient zone.
