As investors nervously anticipate the day the Federal Reserve slows its easy-money policies, the markets are tumbling. As of 12:50 p.m. EDT, the Dow Jones Industrial Average (^DJI 0.21%) is down 206 points, or 1.36%, to slide below the 15,000 mark. The S&P 500 and the Nasdaq have lost 1.49% and 1.53%, respectively.

As my colleague Dan Caplinger noted earlier, the majority of the Dow's components are simply moving lower because of the overall negativity in the markets, rather than company-specific news. But a few of the Dow's 30 stocks didn't even need macroeconomic pressure to underperform today.

Shares of Coca-Cola (KO 0.18%) and Walt-Disney (DIS 0.55%) are down significantly after analysts released negative comments about the companies. Morgan Stanley cut its estimates on Coke today due to lower demand for the company's beverages and unfavorable currency rates. We have seen in the past how a strong dollar can affect a company's quarterly profits, and because Coke's products are found in nearly every country around the world and it continues to see more revenue come from outside the U.S., Coke will surely be negatively affected if the dollar continues to strengthen against other currencies around the globe. Shares of Coke are down 2.2%.

Disney has lost 2.4% today after Goldman Sachs lowered its rating on the stock from "buy" to "neutral" and removed the stock from Goldman's Conviction List. Goldman Sachs cited increasing competition for Disney's ESPN network. ESPN recently announced job cuts and the end of its 3-D programming as ways to lower its operating costs, but increased competition in the sporting market will likely raise the cost of long-term programming rights for sporting events. 

Although fellow Dow component Hewlett-Packard (HPQ -0.68%) received a stock rating upgrade, shares are still down 1.8%. Wells Fargo upgraded HP to "outperform" from "market perform" based on the idea that even without sales improving, HP can deliver growth in net income and free cash flow in the future.
