Many investors get excited when a company announces that it will be splitting its stock, seeing it as a chance to buy into a prosperous company at a "low" price. After all, a "high" stock price can create a psychological barrier that keeps some investors away, which is one reason companies often decide to split their stock in the first place.

With shares of Gilead Sciences (GILD 0.91%) currently trading for a "high" dollar amount close to triple digits, you might be wondering if the biotech giant is going to announce a stock split soon. After all, Gilead Sciences has a history of splitting its stock on a 2-for-1 basis every couple of years, so what's stopping it from doing it again?

While the answer to that question is that absolutely nothing is preventing the company from choosing to split its stock, here are two big reasons I don't think it will happen anytime soon.

Gilead's share price has been heading in reverse

Stock splits tend to take place after a company's share price has experienced a strong upward move, which typically occurs following a series of positive earnings announcements, or from general excitement about the company's future.

While Gilead's long-term history has been unbelievably bright, the company's recent past hasn't been so great. Shares have been selling off for more than a year now, and they are currently down more than 34% from last year's highs.

It's not hard to understand why shares have been heading in reverse. The company's cash-cow hepatitis C business -- which has been the primary revenue driver over the last few years -- looks like it has already peaked. That is going to make it hard for the company to grow its top line in the years ahead, which is a major reason traders have been jumping ship.

That doesn't necessarily mean that shares are going to stay down for good -- I wouldn't be a shareholder if I thought they would -- but since the company's stock has a long climb ahead before it can reach its former high, I have a hard time believing that a stock split is in the cards right now.

Gilead's peers are trading in the triple digits

No company exists in a vacuum, and investors often compare companies against each other when they are considering investment decisions. Gilead is certainly aware of that, so the company is likely to take its cues from what other large biotech stocks are doing when it thinks about splitting its stock.

With that in mind, here's a look at some recent share prices of the biggest biotech companies on the market today, and the last time they decided to split their stock.

Closing Price, 8/18/2016 

Year of Last Split

Alexion Pharmaceuticals $132.80 2011 
Amgen $175.08 1999
Biogen $313.37 2001
Celgene $112.25 2014
Regeneron Pharmaceuticals $411.05 N/A

As you can see, all of these companies have seen their share prices rise into the triple digits, yet only Celgene (NASDAQ: CELG) has felt the urge to split its stock in the past few years. 

Since investors who are interested in Gilead are probably looking at these other companies too, the company is not likely to feel pressure to split its stock. After all, Gilead is actually the lowest-priced stock of the group.

Why it doesn't matter

I certainly understand the allure and excitement that comes from an announced stock split, but it's important to remember that the intrinsic value of a company does not change at all after a stock split is performed. The market capitalization, revenue, profits, P/E ratio, balance sheet, management team, future prospects, product pipeline -- basically, everything remains exactly the same both before and after a stock split.

If you're interested in Gilead's stock, don't let the high share price scare you away. Instead, try to stay focused on the fact that it has a rock-solid balance sheet, an interesting pipeline, and a 2.3% dividend yield, and it's only trading for 7 times trailing earnings.
