Compared to the market and the computer and technology sector Apple is fundamentally cheap. Apple has a buy rating according to ValuEngine with fair value at $606.94 making the stock 9.5% undervalued. Apple has a favorable price-to-earnings ratio at 12.5. The one-year price target is $581.80. Fundamentally, Apple begins 2013 as a buy-and-trade candidate. My proprietary analytics show that Apple has an annual value level at $510.64 suggesting that even if the stock falls below $500 in 2013 it will come back to $510.64 as a pivot, or magnet. Semiannual and annual value levels are $470.21 and $421.05 with a monthly risky level at $604.86, a semiannual risky level at $651.60 and a quarterly risky level at $652.00. Odds are that Apple will stay below $700 for at least the first half of the year. The monthly chart for Apple ended 2012 with a negative profile closing below its five-month modified moving average, now at $569.78. Note that momentum (12x3x3 monthly slow stochastic) reading is declining below 80.00 after being overbought since the end of 2009. This keeps Apple a sell strength stock as 2013 begins, as a new all-time high is unlikely. Chart Courtesy of Thomson/Reuters The weekly chart for Apple is negative but oversold with oversold momentum (12x3x3 weekly slow stochastic) reading below 20.00. A close this week above the five-week modified moving average at $546.35 shifts the weekly chart profile to neutral. If momentum is rising above 20.00 the chart would be positive. Chart Courtesy of Thomson/Reuters Chart Courtesy of Thomson/Reuters The daily chart profile for Apple is positive with a momentum (12x3x3 daily slow stochastic) reading rising above 20.00.
