LONDON -- After a down week last week, the FTSE 100 (INDEX: ^FTSE) is hesitant, and at 5,814 points it's still a way below its 52-week high of 5,989 points. But it could take only a couple of bullish weeks to set a new high.

And I do think that bullishness is returning, with an increasingly varied collection of companies reaching new heights. Today we'll take a quick look at three from very different sectors, all hitting yearly highs.

Sports Direct (LSE: SPD.L)
Sports Direct International has had a great 12 months, reaching a new high of 360.4 pence today before falling back a penny or so to 359.2 pence. That's a gain of 90% since the firm's low point toward the end of 2011.

Recent news includes the release of last month's interim statement telling us of a 25% rise in sales, with profits up around 20%. And on Monday we heard the firm is to buy up some assets and brands belonging to JJB Sports, which is sadly now in administration.

Greencore (LSE: GNC.L)
Greencore Group hit a new 52-week high of 87.75 pence today, taking the shares up 67% since January's low point. The manufacturer and supplier of a range of primary foods went through a slump in recent years, falling to a loss in 2009 before getting back to profits, albeit at a lower level -- and the share price collapsed from the 450 pence levels it commanded prior to 2008.

But with forecasts for better profits this year and next, a dividend of more than 5% expected for this year, and a positive interim update at the end of July ahead of results due in November, we've had a good recovery. And the shares are still only on a forward price-to-earnings ratio of seven.

ITV (LSE: ITV.L)
ITV is back up around peak levels again, touching 91 pence today -- just shy of its 92.25 pence top. That's 65% up on the year's 55 pence low mark and represents quite a turnaround for the TV operator, which crashed as low as 18 pence in 2009.

This year and next have decent but modest dividends forecast, of 2.7% and 3.2%, respectively. And the shares are on a forward P/E of less than 11, which doesn't look high, especially as there is little debt on the books.

Greencore and ITV pay decent dividends, and that can be a good foundation for a long-term portfolio.
