I take my absolute return approach to a deeper level by periodically buying and selling positions during the year. In late February, I suggested that investors cover the short position of Delta Airlines (NYSE: DAL) at $6.35 per share.

In my last update of the stocks on this list, I suggested that I would still be a seller of Delta. Shares of Delta did indeed lose value over the last three months. This move coincided with a blast in oil prices. Airlines are already struggling with a weak economy and excess capacity. Rising jet fuel prices make matters worse.

With such uncertainty, following an absolute return strategy continues to offer investors the biggest bang for their buck. There is no sense in guessing where the market will be down the road.

Instead, buy cheap stocks and sell stocks that are expensive. Then blend the two approaches together in one portfolio and chances are you'll make money.

Even with a huge rally in stocks, the S&P 500 ended the second quarter with a year-to-date gain of 1.78%. That is a vast improvement compared to the 11% loss at the end of the first quarter, but it's a minimal return for taking risk in the stock market.

Investors need to do better -- and they can.

Quarterly earnings could be up year-over-year by the fourth quarter. A low threshold for improvement, as a result of last year's Q3 financial meltdown, could set the stage for the appearance of a recovery, but the ride from here to there will be a difficult one.

Data from Bloomberg and S&P suggests that profits for stocks comprising the S&P 500 Index may be down 21% next quarter. It's still a double-digit blow, but a better result than Q2's estimated 34% -- and far ahead of Q1's 60% year-over-year fall in profits. The driver of a recovery, however concealed by low expectations, is likely to be a combination of unemployment and consumer spending. Last month, we saw unemployment reach a 26-year high, putting obvious constraints on purchasing.

AMR Corp. (NYSE: AMR), the parent of American Airlines, reported earnings for the first quarter on Wednesday. Revenues decreased 15%, and on an adjusted basis, the company lost $1.30 per share. According to this source, the market was calling for a loss of $1.62 per share. Since management was able to beat by such a wide margin, Wall Street decided to reward the stock by bidding it up over 20% (that's how the shares were trading at the time I started this article).

Airlines are still having a problem with the economy. Consumers aren't traveling as much, businesses are cutting back on sending executives across country. Indeed, I'm sure the summer months are going to see a lot of vacation plans being eliminated as people decide to stay closer to home.

The oil surge, which gives new indications daily that it's evolving into the world's third oil shock, bodes tougher times for airlines, and travelers alike, many analysts agree.

Moreover, those tougher times may propel "creative and avant-garde" ideas and strategies to cope with the more-challenging flying environment, by both airlines and travelers, so says C. Leonard Bauer, independent stock analyst.

American Airlines (NYSE: AMR) took the first, bold - - and controversial - - step in the 'era of new flying rules' by announcing that it would charge passengers $15 each way to check their first bag, The Dallas Morning News reported. American also reduced its flying schedule by 11-12% at the same time.

Bauer said travelers should brace for more a-la-carte changes from the major carriers, and some truly creative ones, at that. "The airlines will be looking at every way to reduce fuel usage and cover those expenses from added weight," Bauer said, "When oil was at $20 a barrel, weight was a cost factor, but now at more than $125 a barrel, it's a going-concern factor. These high fuel costs can and will force some airlines out of business if they can't recover these costs. 'Light flight' is in." Bauer added that he does not have a rating on nor own shares of any airline.

Higher oil prices and the surging aviation fuel costs they imply may reduce the benefits of an airliner merger, such as the potential deal between United Airlines and U.S. Airways, but they don't eliminate a merger's long-term positives, an analyst argued Tuesday.

Further, C. Leonard Bauer, independent stock analyst, told BloggingStocks Tuesday the potential United-US Airways union would benefit the sector in that it would be the second merger this year among major airlines in the United States, also known as the legacy carriers.

Shares of UAL Corp. (NYSE: UAUA), parent of United Airlines, are down 88 cents to $14.10, while US Airways (NYSE: LCC) are down 55 cents to $7.79 in Tuesday trading.

Sector right-sizing

"The deal would take another legacy carrier off the table, after the Delta-Northwest merger, and that can only help the sector from an earnings standpoint," Bauer said. "The United States airline sector leads the league in airline route redundancy and duplicate hubs. This second deal would further tighten the sector."

With Delta Air Lines and Northwest Airlines said-to-be-close to announcing a merger, according to Reuters, analysts and business executives will closely-evaluate the proposed deal's details, parsing it to see if it is capable of creating something the land of the free hasn't experienced in quite some time: a profitable major airline.

Turning aside (for the moment) points that argue that with the added cost of public subsidies of aviation and aerospace research, it's hard to envision a U.S. airline as ever being truly 'profitable,' independent stock analyst C. Leonard Bauer told BloggingStocks Monday the merged Delta / Northwest could create an assertive airline capable of racking-up revenue, even as it spurs aviation innovation and change.

The stalled Delta Air Lines (NYSE: DAL) / Northwest Airlines (NYSE: NWA) deal talks should regain momentum next week, provided Delta's management makes progress in talks with its pilots, The Wall Street Journal reported Wednesday (Subscription required).

Further, independent stock analyst C. Leonard Bauer, said that while the Delta / Northwest talks have been stalled at a traditional, formidable hurdle -- pilot seniority and pilot flight schedules -- "the stars now appear to be lining up to get this deal done."

Bauer said that since the talks began, recent data released indicates that the U.S. economy has continued to slow, and is most likely already in a recession -- never a good backdrop for airlines -- which depend on consumer disposable income for a portion of their revenue. Further, oil has resumed its 'regularly scheduled' movement: up, which has increased aviation costs by at least another 10-15%. Or as Bauer put it, "From a fuel cost standpoint, this is no time to fly commercial jets around less than half full." Oil rose $3.71 to $112.21 per barrel -- an all-time high -- Wednesday afternoon after an unexpected decline in U.S. weekly oil inventories.

• Bloomberg reported that The Goldman Sachs Group Inc (NYSE: GS) has been the only major investment bank that has refused to reduce its leverage. In fact, Goldman's adjusted leverage ratio of assets rose to 18.6 at the end of February, from 17.5 at the end of November.

A disagreement among pilots camps on seniority has led to the cancellation of board meetings regarding a potential Delta Air Lines/Northwest Airlines merger agreement, The Wall Street Journal reported Friday (subscription required).

However, independent stock analyst C. Leonard Bauer told BloggingStocks Friday that he expects the issue to be resolved soon and merger efforts to move forward.

"The pilots' seniority item is always the toughest hurdle in airline talks, so a delay and a few hiccups here is not unusual," Bauer said.

Delta's (NYSE: DAL) shares declined 20 cents to $15.93, while Northwest (NYSE: NWA) fell 70 cents to $16.12 on the news in Friday mid-day trading.

The pilot talks involve two branches of the same Air Line Pilots Association, or about 11,000 pilots, The Journal reported.

Is the U.S. airline sector on the eve of another transformation? One analyst thinks it may be, if recent merger rumblings are any indication.

The Delta Air Lines (NYSE: DAL) / Northwest Airline (NYSE: NWA) merger discussions and chatter that Germany's Lufthansa is considering an investment in a potential merger between United (NASDAQ: UAUA) and Continental (NYSE: CAL) suggest to independent equities analyst C. Leonard Bauer that a new commercial aviation paradigm may be up ahead.

"When you look back at the last 30 years, you can say that the 1980s, clearly, was the decade when mergers were needed to meet the demands of the new market, basically the mass consumer market in the U.S.," Bauer told BloggingStocks Wednesday. "Those larger carriers' lowered seat prices led to a huge increase in domestic travel, which helped bring flight travel to the typical citizen."

Continental (NYSE: CAL) closed at $28.70 Thursday.

CAL and United Airlines (NYSE: UAUA) are in advanced negotiations and could complete a combination quickly if Delta (NYSE: DAL) and Northwest Airlines (NYSE: NWA) strike a deal, says Dow Jones.

WTI Crude oil is recently up .12% to $95.57 according to Bloomberg.

CAL March option implied volatility of 71 is above its 26-week average of 58 according to Track Data, suggesting larger price movement.
