NEW YORK ( TheStreet) -- Nymex crude oil peaked at $100.42 per barrel on Sept. 14, which was the day after the FOMC announced QE3. Oil subsequently declined 15.9% to $84.05, into Nov. 7. On Dec. 12, the FOMC announced QE4. Since then, oil has moved sideways to up. Analysis of Nymex Crude Oil ($87.72): On Dec. 14, I wrote
FOMC QE4 Foolishness Pushes Stocks to Cliff Edge . In this post I projected that crude oil had upside potential to its 200-day simple moving average at $92.62. A daily close above the 50-day SMA at $87.63 would enhance this upside potential. A close this week above the five-week modified moving average at $87.79 shifts the weekly chart profile to positive. The chart support is the 200-week SMA at $84.27. Fundamentally, ValuEngine shows the oils-energy sector 5.2% undervalued, with the oil & gas exploration & production industry 10.0% undervalued; the oil & gas field services industry 2.0% undervalued; oil & gas international integrated industry 10.5% undervalued; the oil & gas drilling industry 3.6% undervalued; the oil & gas machinery & equipment industry 5.1% overvalued; and the oil refining and marketing industry 7.2% overvalued. With the technicals improving for Nymex crude oil and with the oils-energy sector the most undervalued of the 16 sectors covered by ValuEngine, it's time for investors to increase allocations to this sector.
