Answer:
Because of the effect of the dividend in the return calculation
Step-by-step explanation:
let´s assume that dividend for Lori´s had been paid at the end of the year, so when a dividend is involved the calculation changes as follows:
![Lori\´s Return=(22.20+1)/(21.38)-1](https://img.qammunity.org/2020/formulas/business/college/fjinc2j40zfoy58wb92sfbjdyauklu72e8.png)
![Lori\´s Return=8.51\%](https://img.qammunity.org/2020/formulas/business/college/j9shptdywtkkw35r7jwmcz6o6lnsv4ejo3.png)
so by the other hand Mike´s return will be naturally less:

![Mike\´s Return=3.83\%](https://img.qammunity.org/2020/formulas/business/college/zq42atricsm4ahpqv6nzjn6d7lou4smon0.png)
