Unfortunately for investors in Caterpillar (NYSE:CAT), another dismal quarter has sent shares to a new 52-week low. Needless to say, the industrial giant's second quarter wasn't anything to write home about:

  • Sales and revenue slipped 13%, while net income slumped 29% year over year.
  • The company lowered its already muted revenue guidance for the full year.

Caterpillar is clearly under tremendous pressure right now, and there's little to suggest that things will improve anytime soon. Take a look at the slideshow below to learn about the three biggest challenges that the company is facing right now, and why things could turn for the worse in the near future.
