Here we present a formal model for Apple, AAPL, share price as based on the consumer price index for motor vehicle parts, MVP, and motor vehicle maintenance and repair, MVR:
Figure 1 shows that the predicted (monthly closing) price is much higher than the observed one during the previous two months when the price fell to $592 (end of October) from $665. The closing price for November 8 is $537.75.
This model is worthless with the current slump. Is Apple a lemon? This means it is judged emotionally rather than objectively.
