Solution Overview

Problem

Existing stock repurchase programs fail to account for market price volatility, leading to inefficient stock repurchases as firms either overbuy when prices are high or underbuy when prices are low.

Innovation Solution

A dynamic stock repurchase model that estimates needs, calculates a base repurchase amount and price using volume-weighted average price, and applies purchase bands with multipliers to adjust repurchases based on market price changes, allowing for strategic buying during both price increases and decreases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a fixed stock repurchase program is used without accounting for market price volatility, then the program is simple to implement, but the firm may repurchase too much stock at premium levels or too little at discounted prices

Engineering Contradiction:
Improvestock repurchase program structureVSAvoidstock repurchase efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent applies dynamics by transitioning from a fixed stock repurchase program to a dynamic program that adjusts purchase amounts based on real-time market price fluctuations. The system continuously monitors stock prices and modifies repurchase quantities accordingly, allowing the firm to buy more when prices are low and less when prices are high, thereby optimizing repurchase efficiency while managing complexity through automated price-based adjustments

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback mechanisms where market price information is continuously fed back into the repurchase decision-making process. The system uses current stock prices as feedback to adjust repurchase quantities, creating a closed-loop system that adapts to market conditions. This feedback approach enables the firm to respond to price changes and optimize its repurchase strategy based on actual market behavior

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the firm repurchases stock without considering price fluctuations, then the execution process is straightforward, but the firm fails to take full advantage of discounted prices or avoid premium prices

Engineering Contradiction:
Improvestock repurchase executionVSAvoidoptimal stock repurchase quantity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent applies parameter changes by making the repurchase quantity a variable parameter that changes with market conditions. Instead of using a fixed repurchase quantity, the system adjusts the quantity parameter based on stock price levels, allowing the firm to optimize the amount purchased at different price points. This dynamic parameter adjustment enables the firm to maximize the quantity purchased when prices are low and minimize purchases when prices are high

Inventive Principle:
Principle #35Parameter changes

AI summary

Various methods for constructing a model for a firm to repurchase stock of the firm are disclosed. The method may include estimating stock repurchase needs for the firm for at least a portion of a fiscal period; calculating a base stock repurchase amount associated with at least one trading period included within the fiscal period portion; calculating a base stock repurchase price associated with the stock of the firm; and constructing a stock repurchase model for generating an amount of stock to repurchase during the fiscal period portion based on the calculated base stock repurchase amount and the calculated base stock repurchase price.
