Are These High-Flying Stocks Headed for a Fall?

If there's something that can keep this market down, it's yet to occur. Bad news can't keep the Dow down for long. Surprises can't stun the S&P. Indexes have been steadily moving higher all year, to the delight of stockholders and the annoyance of perma-bears. Some stocks have been on a rocket, despite little rationale to indicate their long-term viability. It's important to cast a critical eye on any company that seems too good to be true, even though your favorite analysts might be giving it a big thumbs-up.

Getting a little too hot in here
There are few analysts who expect highfliers to turn sour, so my early screen included stocks with positive forward projections, but focused on companies with high P/Es or negative earnings. All of my choices saw big earnings losses this year, and projections call for losses going forward as well. For one stock, there's no profit on the horizon at all. How might these rockets run out of fuel? Let's find out.

A wild ride
Six Flags is an interesting case. The amusement park company emerged from bankruptcy in 2010 with lower debt and a better focus, but it's going to take time to improve performance beyond the impact of net operating losses that will goose its bottom line for a while. In the meantime, performance has been flat for years, which points to a resistance to economic headwinds but also speaks to the difficulty of growing income at well-established destinations.

The 5.2% dividend yield is nice, but combining that high payout with an ill-advised stock buyback plan seems like the wrong approach coming out of bankruptcy. Warm weather and improving economic outlooks could help Six Flags, but they're also good news for competitor Cedar Fair (NYSE: FUN), an operator that's both avoided bankruptcy and has been slowly and steadily reducing liabilities for years:

I think both companies have room to run over the long term, but Six Flags' rise looks like the ramp up a steep coaster track, about to take the plunge. Don't hop on this one at the wrong time; wait for it to come back to the station and strap yourself in. My underperform call on this one will only be for a few months.

That store is so '90s
Hot Topic is a company of interest to me for a few reasons. It's been years since I was a high school student myself, but younger siblings have been around to remind me of the company's irreverent -- and often hideous -- garb for some time. Beauty is in the eye of the beholder, and the gloomy economy should have driven kids to this company's outlets for the past few years. But that hasn't happened:

There's little of note that's positive in Hot Topic's long-term performance, and present operations aren't exactly offering much hope either. Fool contributor Sean Williams is as gloomy as a Hot Topic store's interior on its recent moves, dinging store closings, rising inventory levels, and inexplicably raised dividends in spite of continued poor performance. If so much underwhelming performance doesn't convince you, perhaps my CAPScall ode to Hot Topic will. I'm in the red on my call right now, but I don't expect that to last for long.

It's a gas
Westport is a subject of intense debate around Fooldom. On one hand, many are fans of the company's key role in natural gas vehicle conversions. On the other, it's hard to deny that Westport has grown so much that its future profitability (which isn't here yet) may already be baked in. We do have different Foolish opinions, and while I like the idea of transforming our transportation fleets to run on natural gas, Westport's ramp-up to profitability leaves it open to assault on several fronts.

While the company's partnership with Cummins (NYSE: CMI) gives it a foot in the door in the trucking industry, Westport's engine conversions have yet to sell 1,000 units per year. Compare that to electric cars, which have broad government support, are being built by multiple automakers, and are already selling in the tens of thousands annually. Westport's scale is so small that it's difficult to award it the nat gas vehicle crown before any vehicle manufacturer makes a concerted push toward mass adoption. Most analysts already feel that Westport's meteoric rise is reaching its apex, and the company is years away from profitability.

Few stocks can keep growing as fast as Westport with no hope of profit. The stock has mocked the bears for years as it's kept making gains. But it's gone a decade without profit or positive free cash flow. By the time the red ink turns black, there may be no more gains left before competition finally gets into the game.
