NEW YORK (TheStreet) -- Caterpillar (CAT) - Get Report and 3-M (MMM) - Get Report  third quarter earnings will have been dragged down by the strong dollar and weakening global economic growth. Investors should establish strategies to sell these stocks after they report results before the opening bell on Thursday. 

This risk was clearly reflected in the disappointing earningsCoca Cola (KO) - Get Report reported before the opening bell on Tuesday. Coke's global sales were hurt by slowing consumer spending and the strong dollar.

Industrial products giant Caterpillar depends upon overseas markets for more than half its sales of construction and mining equipment, engines and gas turbines. The company beat earnings estimates in the first quarter and the stock continued higher to a multiyear intraday high at $111.46 on July 16 anticipating solid second quarter results. Despite beating analysts estimates the stock gapped below its 50-day simple moving average on July 24 due to a revenue dip from lower mining demand.

Caterpillar traded as low as $99.11 on Aug. 1, then followed the Dow 30 higher. After trading as high as $109.73 on Sept. 2, the stock cascaded lower and broke below its 200-day SMA on Sept. 25 to as low as $90.05 on Oct. 15.

3-M is a multi-sector conglomerate with worldwide sales of industrial and consumer products exposing the company to the strong dollar and slowing global growth. The company matched earnings estimates in the first and second quarters and joined the Dow 30 in setting an all-time intraday high at $147.87 on Sept. 19. The decline to its Oct.15 low at $130.60 was a decline of 11.7%, in correction territory.

TheStreet Ratings team rates CATERPILLAR INC as a Buy with a ratings score of B. TheStreet Ratings Team has this to say about their recommendation:

"We rate CATERPILLAR INC (CAT) a BUY. This is driven by a few notable strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its increase in stock price during the past year, growth in earnings per share and increase in net income. We feel these strengths outweigh the fact that the company has had generally high debt management risk by most measures that we evaluated."
