After tumbling to a low of $33.98 a barrel on Feb. 12, crude oil more than doubled in price, soaring to $69.82 on the New York Mercantile Exchange (Nasdaq: CME) – before tumbling nearly 4% on Thursday on a worse-than-expected jobs report.

Indeed, Money Morning predicted precisely that kind of a run-up for crude oil, first in January and then again on April 16.

As a basis for those previous analyses of the oil market, we cited the declining value of the U.S. dollar, falling production, and the possibility that demand for oil would soar as the global economy emerges from the worst financial crisis since World War II. And those factors continue to suggest that the price of oil will rise over the long-term. 

However, while we still believe the long-term outlook for oil prices is bullish, it’s important to note that the recent oil price rally is not supported by supply/demand fundamentals. It is the result of a shift in market sentiment and a corresponding reversal in U.S. stocks, not a material change in the global economy.

And because the five-month rally has proceeded at an exceptionally quick pace, it’s made prices more volatile. That means prices could experience a significant correction in the short-term.

So here’s what you need to know as we approach a major inflection point for one of the world’s most volatile commodities.

What to Make of Oil’s Recent Rally

Prior to Thursday’s stumble, oil prices had soared about 106% since sliding below $34 a barrel in February. The main reason for this jump has been the so-called "green shoots" of economic recovery led investors to believe oil was oversold and that the global economy will return to growth much sooner than originally predicted.

This is highlighted by the fact that the U.S. stock market has experienced an almost simultaneous recovery. The Dow Jones Industrial Average is up about 5% from February, and 30% from mid-March. Meanwhile, the Standard & Poor’s 500 Index has climbed about 11% since Feb. 12 and is up more than 30% from its March lows.

"Historically, equities have been a leading indicator of economic growth and commodities have been a coincident indicator," Hussein Allidina, head of commodities research at Morgan Stanley (NYSE: MS), told CNNMoney.com. "Right now, you’re seeing commodities and equities move up together as money comes back in at the same time."

However, there are other factors at work, including the declining value of the U.S. dollar and a shift in the futures market.

Because oil is priced in dollars, any decline in value of the U.S. currency drives crude oil prices higher.   During last year’s huge run-up in oil prices, the U.S. dollar fell to a record low of $1.59 against the euro, though it subsequently rebounded. Since oil began its current rally on Feb.
