The Dow Jones Industrial Average was off to a rough start in 2015, before rebounding this week.

Here are the four worst-performing Dow stocks so far:

4. American Express Co AXP 0.73%

American Express stock is down 5.8 percent already this year. The struggling financial sector has dragged the credit card company down. The company reported earnings earlier this week.

3. Caterpillar Inc CAT 1.6%

Caterpillar stock is down 6.7 percent since the turn of the calendar. Oil industry demand for Caterpillar’s heavy machinery will likely be very soft in the foreseeable future, and investors are worried about how that will affect the company’s bottom line.

Caterpillar reports Q4 earnings on January 27.

2. Goldman Sachs Group Inc GS 0.32%

Goldman Sachs stock is down 8.6 percent since New Years Day.

Unprecedented levels of regulation on the trading practices of big banks, along with a continued environment of low interest rates have put major pressure on bank margins.

1. JPMorgan Chase & Co JPM 0.85%

JP Morgan has earned the dubious distinction as the worst-performing stock in the Dow 30 so far this year, as well as the only stock to have suffered a double-digit percent drop at -10.7 percent. Oppenheimer recently said the stock was still cheap.

Want to learn more about the stock market? Or maybe you just want to be able to look sophisticated in front of your coworkers when they ask you what you are reading on your Kindle, and you’d prefer to tell them “Oh, I’m just reading a book about stock market analysis,” rather than the usual “Oh, I’m just looking at pics of my ex-girlfriend on Facebook.” For these reasons and more, check out my book, Beating Wall Street with Common Sense. I don’t have a degree in finance; I have a degree in neuroscience. You don’t have to predict what stocks will do if you can predict what traders will do and be one step ahead of them. I made a 400% return in the stock market over five years using only basic principles of psychology and common sense. Beating Wall Street with Common Sense is now available on Amazon, and tradingcommonsense.com is always available on your local internet!
