We investors tend to spend a lot of time thinking about whether and when to buy into various stocks, and much less time thinking about when to sell. Many time, we sell when we shouldn't -- or hang on when we shouldn't. Those can be costly mistakes. Here are three suggestions regarding when it's smart to sell or hang on.

Don't sell just because the price shot up

Cory Renauer: Trading in and out of positions is a great way to underperform the market for more reasons than one. To use an example with a nice, round figure, consider Johnson & Johnsonstock. Suppose you bought shares of the healthcare conglomerate near the beginning of the year with a limit order of $100.00 per share.

Following an early dip, the stock has had a great year, and on the first of August you could have sold off your shares, locking in a juicy 25% profit. If you're in this boat and kicking yourself now that the stock is only up 15.76%, relax.

The best thing to do in this case is something many of us excel at: nothing. If you had sold in August, you would have realized a short-term capital gain -- accounting lingo for selling an asset held for less than one year at a profit. In the U.S., short-term capital gains are generally taxed at the same rate as income from your job, but investments held longer than one year are taxed at a 15% rate for most people.

You can realize the gain after one year or in the next century, but you'll be taxed only once. In the meantime, J&J will continue reinvesting any profits it doesn't return to you in the form of dividends and share repurchases -- something the company does quite well.

Even if you trade stocks held within a retirement account that's not subject to capital gains taxes, statistics say you're better off holding on to shares for as long as the company's profits continue growing. In case you haven't heard, the majority of actively managed mutual funds fail to beat their benchmarks over time -- and those benchmark indexes contain companies without earnings growth. If most fund managers with legions of trained analysts at their disposal can't outperform a simple buy-and-hold strategy, your chances of doing much better are extremely slim.

Don't sell just because the stock price falls

Brian Feroldi:If you pull up a long-term chart of any of the most successful stocks in history, you'll notice they all have something in common -- at some point, the share price took a huge beating. Even massive winners such asAmazon.com, Starbucks, Microsoft, Berkshire Hathaway, and many moreall saw their share prices drop by at least 50%, which undoubtedly caused some shareholders to bail. While selling any of those stocks while they were dropping probably felt like a smart move in the short term, each of those companies went on to produce multibagger returns from after they fell, causing those who sold early to miss out on massive gains.

Ever since someone pointed that out to me, I've become a firm believer that you shouldn't ever sell a stock just because its share price is tumbling. Instead, the smarter play is to focus your attention on how the business itself is performing and do your best to ignore the short-term movements of the share price.

A good example of this principle in action is the recent history of Intuitive Surgical, the leader in robotic surgery. The company's shares traded for over $550 each in early 2013, but then the company's growth engine started to stall thanks to a temporary decline in sales of its da Vinci system in 2014. Traders slammed the shares, dropping them below $350 over fears that the company's days of high growth were over.

While there's no doubt that Intuitive Surgical faced some real short-term challenges, the company's position as a leader in the robotic-surgery market was never really in question. Intuitive then went on to roll out a new da Vinci system that's proved to be a hit with providers. Revenue is back to growing at double-digitrates,margins are expanding, and the company's lead looks as strong as ever.

Given the company's recent results, shares have rebounded sharply, recently trading for over $680 each. Thus, even those who bought at the peak in 2013 are currently far into the green.

The lesson here is clear: If you've bought shares of a strong company whose future you truly believe in, don't be in a rush to sell just because shares take a short-term nose dive. Rather, keep your attention focused on the company's business and future prospects. As long as those things are still going well, then the share price will take care of itself.

Dosell instead of stubbornly hanging on to a loser

Selena Maranjian: Many times, investors hang on to a stock when they shouldn't -- because they've lost money in it and they're waiting for it to increase in price so that they can at least get their money back. That can sound kind of reasonable, but it isn't. Here's why.

Imagine that you bought shares in, say, Home Surgery Kits, Inc. (ticker: OUCHH) because you were very bullish on the company's future and you believed its shares were undervalued. So far, so good. But the shares fall in value instead of rising. Maybe a bunch of gruesome mishaps people experience with the kits are covered heavily in the media, leading to a major sell-off of shares and sending the stock price down. Many people have lost faith in the company -- and so have you.

Let's say that you spent $5,000 for 100 shares of the stock when it was trading at $50 and you're now down $3,000 because shares are trading around $20 apiece. You can hang on and wait, hoping that the shares will inch up to $25, and then $30, and then maybe even $50 -- so that you can recoup some (or, ideally, all) of your loss. Remember, though, that you don't have a lot of confidence in the company any more. So that recovery actually doesn't seem so likely. You're really being more stubborn than sensible.

Instead, remember that there are thousands of companies in which you can invest, many of which are strong, growing, and undervalued. Sell your deflated shares and find one or more of those companies -- ones where you're much more confident that they will grew. Then, by moving your remaining $2,000 into them, you'll stand a much better chance of recouping your loss. You'll just be doing so with another company or companies.
