Is growth back? It sure seems like it. Once-speculative firms such as TASER International (NASDAQ:TASR), which is up 60% in 10 weeks, are building momentum daily.

More gains could be on the way. A survey of leading investment managers conducted by the Russell Investment Group says the growth rally will continue through the remainder of the year. And Fidelity Magellan manager Harry Lange says growth isn't just good, it's cheap. "I am still convinced that this is the place to be and if anything ... I have been adding even more to growth stocks," Lange told Reuters.

Don't dump the downtrodden
Surely Lange's optimism draws from years of success with growth stocks as manager of Fidelity Capital Appreciation, which thumped the market during both the go-go years of the bubble and the ugly aftermath that ensued. But there's also more to it than that. History, for one.

Growth stocks did better than value for the six years between 1994 and 2000 as technology stocks soared. Value stocks have been on a roll since. Now, as earnings growth begins to show signs of slowing, fast movers unaffected by general economic malaise could return to prominence. That's why, when Lange took the helm of the Magellan fund, he dumped ExxonMobil (NYSE:XOM) and bought Apple.

Funding growth
Then there's small growth daredevil Vanguard Explorer (VEXPX), which trailed the market by six percentage points in 2006. This year, Explorer's managers are betting on speedsters like biotech Cephalon (NASDAQ:CEPH), payment processor Alliance Data Systems (NYSE:ADS), and Linux specialist Red Hat (NYSE:RHT) and their gutsy style is beating the S&P 500 by more than three percentage points as I write. (These firms are expected by Street analysts to boost earnings by more than 15% annually over the next five years.)

Be a rebel with a cause
Here at Fool HQ, we've begun to see the turn as well. Last summer, David Gardner's Rule Breakers portfolio was bleeding red. And the quest for the next Starbucks was stuck in the mud. No longer. Today, the portfolio is once again beating the market and features eight stocks that have at least doubled.

How did it turn around? My analysis points to three traits shared by our biggest winners:

  1. A competitive advantage in an important, emerging market.
  2. A sustainable business growing at an above-average pace.
  3. Top-flight mangers that have a clear vision for what they wish to accomplish.

As you seek the sort of multibagger returns that helped growth gurus like Peter Lynch and Philip Fisher make millions from thousands, remember these factors.
