LONDON -- The FTSE 100 (INDEX: ^FTSE) has been wobbling and going nowhere this week, and today we saw more of that: It was almost completely flat at 5,663 points by midday. Markets appear torn between a relaxing of the eurozone panic, further indications of the global economic slowdown, and an uncertain interim reporting season just ahead of us.

But whatever the overall sentiment, individual companies are going about their everyday business. Let's look at three constituents of the FTSE indexes that are perking up today.

JD Wetherspoon (LSE: JDW.L)
Shares in pub chain JD Wetherspoon put on a modest 2.3% to 432 pence on the release of a good-looking preclose statement. Ahead of its full-year results, due on Sept. 14, we heard that overall sales were up 9.2% for the year, with like-for-like sales up 3%.

The firm also bought back 5.6 million of its own shares during the year for a cost of 22.7 million pounds, which seems to have been a good move while the shares were down; they're now up 18% from the year's low of 367 pence in May.

InternetQ (LSE: INTQ.L)
InternetQ climbed 5.8% 222 pence after giving us a bullish trading update this morning. The firm, which specializes in mobile marketing and entertainment, told us that it "has continued its strong organic growth and anticipates first-half 2012 revenue to comfortably exceed 30 million euros, representing organic growth of over 50%."

The share price has been erratic over the year, falling as low as 117 pence in late November -- anyone who bought then would be up 90% now.

Sefton Resources (LSE: SER.L)
Oil and gas producer Sefton Resources rebounded by 5% to 1.73 pence this morning after a positive operational update. The firm, which has interests in California and Kansas, indicated that it is reaching a turning point as a number of its projects are reaching critical stages. According to Chairman Jim Ellerton, this "will see the Group become a far larger business and turn the value that has been created into profits."

Sefton Resources shares have slumped around 40% in the past 12 months.
