Similar to Dupont, I selected Eastman Chemical (NYSE: EMN) as a stock to avoid due to rising input prices and low margins. It is a simple formula that cannot be broken: If a company cannot pass along higher costs, it will make less.

The market has yet to grasp that concept with respect to EMN. The stock has more than doubled since bottoming in March and has skyrocketed during the second quarter. This is in stock contrast to the poor performance at Dupont.

For the first two months of the second quarter Boeing (NYSE: BA) was on fire. BA gained significantly during that time, but then the company announced a delay in their much-awaited DreamShip -- a delay that opened the door for the airlines to cancel orders. Speculation based on that scenario slapped the stock back down to the flat line for the second quarter.

Unfortunately, the news does not get better for Boeing. There is too much capacity in the airline space, and new planes are not needed.

I would be a seller of Boeing today.

Given the economic crisis and global recession, I hypothesized that multinationals may suffer as a result of a strong dollar. The idea being that investors would flock to the dollar in search of safety. Over the last quarter though, the reverse has been true.

The dollar weakened significantly as investors bet against the greenback due to inflationary spending in the U.S. As a result, the multinationals have been big winners in the last quarter.

3M (NYSE: MMM) though was only up slightly in the second quarter as the company's products failed to capture the imagination of buyers across the globe. When the dollar strengthens in the latter half of 2009, look for MMM to stumble.

Next: Stock to Avoid #4

Another stock leveraged to the oil market is Dupont (NYSE: DD). Because many of the company's products are derived from crude oil, rising oil prices negatively impact profit margins. The only recourse, then, is to raise the price for consumers. But doing so in this environment is unlikely given the weakness in the economy.

As a result, the dynamics of the market are such that profits for DD will be lower in the near term.

That puts the company in a bit of a Catch-22.

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.

The interest in using natural gas as an alternative to crude has helped natural gas-based companies appreciate in value. Chesapeake Energy (NYSE: CHK) has benefited from that interest, with a gain of more than 20% this year.

CHK is an interesting story in that during the craze in energy prices in 2008, the CEO of the company was forced to liquidate his entire position. That forced selling created an opportunity to buy the stock at an incredibly cheap price, even beyond the artificially low energy prices reached earlier this year.

The China miracle is back on track, and with it comes speculation for resource demand as a result of huge economic growth. Within the oil sector, the coal group has seen big gains given its use in power generation. In China, that is particularly true, with the country seeing new power plants open on a regular basis.

Yanzhou Coal Mining (NYSE: YZC) appears to be in the sweet spot. Investors seem to agree and have pushed YZC up almost 70% in 2009. China is an appealing play, but by no means certain.

Drill, baby, drill was the calling card of the Republican Party during the last presidential election.

With high oil prices and rising demand, finding new sources of oil is imperative. Given environmental concerns, offshore drilling is one space that still offers meaningful potential to increase domestic supply.

Diamond Offshore Drilling (NYSE: DO) operates some 45 deep water rigs that are keeping extraordinarily busy with oil prices on the rise.

Suncor Energy (NYSE: SU) is a vertically-integrated oil company located in Canada. Unlike its vertically-integrated brethren in the United States, this Canadian stock is up more than 40% this year. By comparison, Exxon Mobil (NYSE: XOM) is down 13%, and ConocoPhillips (NYSE: COP) is down more than 20%.

The reason for the big difference in performance is the weakness in the dollar. That makes Canadian-based Suncor more valuable to investors.

McDermott International (NYSE: MDR) is a global oil engineering and construction company that specializes in offshore oil and gas construction and power generation systems.

Although more diversified than pure oil plays, McDermott has benefited greatly from the increase in price in crude.

The speculation is that McDermott will be quite busy with construction projects, as drillers are more active with the higher prices.

You have to love OPEC. It's not uncommon for the barons of the giant cartel to voice their interest in seeing oil at such-and-such a price.

Recently, OPEC reiterated its desire to see oil prices at $80 per barrel. This, they claim, is the price needed to spur additional investment in crude projects. Apparently, anything less will result in oil sitting idle in the ground.

Winnebago Industries (NYSE: WGO) traveled to Wall Street on Thursday to deliver its Q3 earnings numbers. The market thought that the results were worthy of a 10% increase in the stock price. Winnebago closed yesterday at $7.15 per share. The 52-week low on the stock is $3.14. Volume was active during the trading session. So, is Winnebago a buy?

Let's check out some of the stats. According to the press release (pdf file), net sales saw a very steep decline of more than 60%. Winnebago lost 29 cents per share in this year's third quarter versus a profit of 10 cents per share in last year's similar period. However, analysts expected a loss of 27 cents per share. Since Winnebago didn't beat the analyst community, you have to wonder why the market was so excited and in a frenzy to bid shares higher.

The move in Skechers USA (NYSE: SKX) from the March lows pales in comparison to the triples or more seen in some retail stocks.

That said, SKX did more than double in value before pulling back in early May. Much of that gain happened on the heels of a better-than-expected earnings report that showed the company making a small profit.

Does it make sense to buy a stock that is up 300%?

If so, I would want to be darn sure about future earnings prospects needed to support a premium valuation.

In the case of AnnTaylor (NYSE: ANN), I'm not convinced that future prospects are secure.

Recently, the company announced cautious guidance suggesting that difficulties will persist through the remainder of the year. This comes in the aftermath of announcing a first quarter loss and decline in same-store sales.
