Should you sell Orthovita (Nasdaq: VITA) today?

The decision to sell a stock you've researched and followed for months or years is never easy. If you fall in love with your stock holdings, you risk becoming vulnerable to confirmation bias -- listening only to information that supports your theories, and rejecting any contradictions.

In 2004, longtime Fool Bill Mann called confirmation bias one of the most dangerous components of investing. This warning has helped my own personal investing throughout the Great Recession. Now, I want to help you identify potential sell signs on popular stocks within our 4-million-strong Fool.com community.

Today I'm laser-focused on Orthovita, ready to evaluate its price, valuation, margins, and liquidity. Let's get started!

Don't sell on price
Over the past 12 months, Orthovita is down 46% versus an S&P 500 return of 11.3%. Investors in Orthovita are no doubt disappointed with their returns, but is now the time to cut and run? Not necessarily. Short-term underperformance alone is not a sell sign. The market may be missing the critical element of your Orthovita investing thesis. For historical context, let's compare Orthovita's recent price to its 52-week and five-year highs. I've also included a few other businesses in the same or related industries:

As you can see, Orthovita is well off its 52-week high. If you bought near the peak, now's the time to think back to why you bought it in the first place. If your reasons still hold true, you shouldn't sell based on this information alone.

Potential sell signs
First, let's look at the gross margins trend, which represents the amount of profit a company makes for each $1 in sales, after deducting all costs directly related to that sale. A deteriorating gross margin over time can indicate that competition has forced the company to lower prices, that it can't control costs, or that its whole industry's facing tough times. Here is Orthovita's gross margin over the past five years:

Orthovita is having no trouble maintaining and increasing its gross margin, which tends to dictate a company's overall profitability. This is solid news; however, Orthovita investors need to keep an eye on this over the coming quarters. If margins begin to dip, you'll want to know why.

Next, let's explore what other investors think about Orthovita. We love the contrarian view here at Fool.com, but we don't mind cheating off of our neighbors every once in a while. For this, we'll examine two metrics: Motley Fool CAPS ratings and short interest. The former tells us how Fool.com's 170,000-strong community of individual analysts rate the stock. The latter shows what proportion of investors are betting that the stock will fall. I'm including other peer companies once again for context.

The Fool community is rather bullish on Orthovita. We typically like to see our stocks rated at four or five stars. Anything below that is a less-than-bullish indicator. I highly recommend you visit Orthovita's stock pitch page to see the verbatim reasons behind the ratings.

Here, short interest is at a high 6%. This typically indicates that large institutional investors are betting against the stock.

Now, let's study Orthovita's debt situation, with a little help from the debt-to-equity ratio. This metric tells us how much debt the company's taken on, relative to its overall capital structure.

Orthovita has been taking on some additional debt over the past five years. When we take into account increasing total equity over the same time period, this has caused debt-to-equity to increase, as seen in the above chart. Based on the trend alone, that's a bad sign. I consider a debt-to-equity ratio below 50% to be healthy, though it varies by industry.  Orthovita is currently above this level, at 77.4%.

The last metric I like to look at is the current ratio, which lets investors judge a company's short-term liquidity. If Orthovita had to convert its current assets to cash in one year, how many times over could the company cover its liabilities? As of the last filing, Orthovita has a current ratio of 6.79.This is a healthy sign. I like to see companies with current ratios greater than 1.5.

Finally, it's highly beneficial to determine whether Orthovita belongs in your portfolio -- and to know how many similar businesses already occupy your stable of investments.

The final recap

Orthovita has failed two of the quick tests that would make it a sell. This is great, but does it mean you should hold your Orthovita shares? Not necessarily. Just keep your eye on these trends over the coming quarters.
