The Dow Jones Industrial Average (INDEX: ^DJI) finished up close to flat today. But some names got hit hard. These three tumbled the most:

Company

Today's Stock Price Change

Travelers (NYSE: TRV) (2.1%)
Procter & Gamble (NYSE: PG) (1.8%)
Verizon (NYSE: VZ) (1.5%)

Each of these companies reports their quarterly earnings later this week. Travelers and Verizon will report tomorrow, whereas Procter & Gamble will be reporting on Friday.

Travelers is coming off a difficult 2011 for property and casualty insurance. Losses pushed its combined ratio up to 104.5% in its third quarter, meaning it paid out more in claims than it earned in premiums. But barring any major disasters, it's expected to report much better earnings tomorrow -- $1.46 per share versus $0.80 in the previous quarter, or $1.98 in the previous year's fourth quarter.

For Procter & Gamble, the consensus earnings estimate among the dart-throwers is for $1.13 per share, down slightly from $1.12 in last year's quarter. But not all's wrong with the consumer products stalwart, despite an analyst at Stifel Nicolaus cutting its earnings estimate today; investors will want to keep an eye on how P&G's fast-growing international operations are coming along. In the last year alone, they've increased nearly 7% to $52.1 billion.

Verizon is expected to report earnings of $0.49 per share tomorrow, versus $0.52 in last year's quarter. Eager investors will also finally find out how many iPhone subscribers Verizon added since the launch of Apple's (Nasdaq: AAPL) iPhone 4S. Apple is also reporting tomorrow. Analysts expect it to generate some $39 billion in sales, including 30 million iPhone and 13 million iPads. Wow.

Today Travelers, Procter & Gamble, and Verizon got torched, but it's important for us to remember that what happens to stocks on a day-to-day basis matters far less than their long-term performance.
