Allstar’s cumulative net income has steadily improved each period. From start to finish, Allstar’s cumulative net income has increased by $727.08 million. The average increase from each period was roughly $91 million. Our largest increase in net income was in period six when it increased by over $25 million after we introduced our new allergy product, All right. We saw the lowest increase in our cumulative net income between periods one and three. Team A believes that we could have increased our net income during this time by purchasing more reports and making our decisions based on the results. We saw an increase in our net income when we added additional sales force and used more of our remaining budget on advertising and promotion.
Allstar’s stock price ranged from $38 to $50 until period six when it increased to $62.69. The strongest growth in stock price occurred in period seven when it increased $20.16 for a total of $82.85. This large increase can again be attributed to our new allergy product, All right. Similar to our net income, our stock price was lowest between periods one and three. We saw great improvement when we started purchasing additional reports to assist in our decision making.
We anticipate continuing growth for the Allstar brands in period nine. Throughout the simulation, All round has been in the growth phase of the product life cycle. As All round transitions into period nine, we expect that it will enter the maturity phase and we will see sales start to slow down for the All round product. We will continue to focus our efforts on retention of our customers and keeping our strong brand recognition.
Since inception, All right has managed to capture 43.9% of the allergy market share in just three periods. In the introduction phase, All right had a pioneer advantage which allowed us to have significant profit improvement and market penetration in a short amount of time. All round’s successful brand recognition provided a significant advantage to All right and allowed us to move from the introduction phase to the growth stage quickly. All right will be the focus in period nine. Ninety percent of the remaining $4 million budget will go towards All right’s promotion, advertising and additional sales force. We predict that these changes will result in a significant increase to our net income as well as a raise in our stock price to the $90 range.
