Closing Bell: Yo-Yo trading (TXN, DPS, DNDN, AFFX, MMM, S)

Texas Instruments Incorporated (TXN) was down on raised guidance because the "raised" part of guidance was in-line with what was already expected and telegraphed by competitors. Shares were down 1.75% at $25.87 late in the trading day.

Dr Pepper Snapple Group Inc. (DPS) rose on word that it will receive $900 million for licensing certain brands to PepsiCo after Pepsi completes the buyout of its two largest bottlers in 2010. Dr. Pepper Snapple shares were up 1.4% at $27.12 late in the day.

Dendreon Corporation (DNDN) sold off, but not as much as you might expect, on its report that it is selling 15 million shares of common stock through JPMorgan and Deutsche Bank. Shares were down 2.8% at $25.88 late in the day.

Affymetrix (AFFX) was up all day on hopes that it could be the next takeover of the biohealth and life sciences companies acquired. While nothing is definitive, the stock was up 14% at $5.41 late in trading day.

Sprint Nextel (S) continued its trading yo-yo this week. Shares were off yesterday, but back up on an analyst upgrade. Shares were up 5.6% at $4.13 right before the closing bell.
