Market Insider | What's Shaking | Stocks to Watch

Take a look at some of Tuesday's midday movers:

Whirlpool surged after the company announced an increase in its quarterly dividend of 25 percent to 62.5 cents a share.

Facebook jumped after the social-networking giant announced that its mobile software "Chat Heads" will be coming soon to its Apple apps.

Vulcan Materials gained after an upgrade to "buy" from "neutral" at Sterne Agee. Analyst said Monday's slide in the construction-materials firm presented a good buying opportunity for investors.

Earnings were the main driver for stocks with big market moves:

W. W. Grainger hit a 52-week high after the company said first-quarter profits improved a better-than-expected 13 percent on stronger sales. The industrial-goods supplier also raised the low end of its 2013 sales and earnings guidance to reflect its strong performance in the first quarter.

Goldman Sachs moved lower even after the financial giant beat the top end of analysts' expectations in its quarterly earnings report.

Wolverine World Wide traded higher after the company posted better-than-expected first-quarter results on strong business in the United States despite "challenging conditions in Europe."
