Four Reasons To Sell A Stock

Published in Investing Strategy on 19 June 2009

Selling is often seen as the toughest investing decision. Here are four simple ways to help you know when it's the right time to sell.

The hope of profits and the joy of ownership make buying shares a fairly simple decision, especially in comparison to the tormented hair-pulling that's often associated with selling.

When to jettison a stock is a difficult decision, so we won't pretend there's a one-size-fits-all formula. However, guidelines can make selling decisions easier. Over at our US-based premium newsletter, Motley Fool Pro, the following are four key factors in any sell considerations.

1. Valuation

The most cited reason to sell -- a fairly valued stock -- is also the most difficult to nail down.

We estimate the fair value of a company before plonking money down to buy, determining intrinsic value by digging into financial statements, analysing business prospects and free cash flow, and making conservative assumptions about future growth.

Buying undervalued stocks, we wait patiently for a price that's close to our estimate of fair value, reassess at that point, and then ruthlessly sell if the stock looks fairly priced. Having personally bought MasterCard in the past around $150, after it cleared $220 -- nearly a 50% gain for a large company -- the stock looked fairly priced. It was difficult to sell such a strong business, but it was the right move. With the stock at $163 one year later, I can consider buying again.

It's not always that easy. Amazon.com has looked expensive for years, but continues to reward shareholders. If valuation is perplexing you, you need to consider selling just some of your shares (to lock in profits), or protect your gains through other means, and then consider other factors in your sell decision.

2. Fundamental Change in the Underlying Business

Companies are always undergoing change -- sometimes for the better, oftentimes not. As patient investors, we're willing to tolerate minor, fixable hiccups along the lines of a weak quarter or delayed product launch. We're not so forgiving of major blunders -- think acquisitions that undermine the core business, getting surpassed by a competitor, or a string of failed expansion attempts. WPP's (LSE: WPP) acquisition of fellow marketing group Taylor Nelson Sofres last year for over £1 billion was questionable enough to make many sell. Whenever a business undergoes a significant change, you need to put on your thinking cap and reassess.

3. Challenges to Your Investing Thesis

When you make a buy decision, you should write down your reasons and keep them handy. Knowing the most important drivers behind your buys, you can reassess your decision if any part of your thesis is challenged.

Because valuation is part of any thesis, threatening changes can include dividend cuts, deterioration of margins, weakening free cash flow --- or economic shifts. Keep the big picture in mind. If you'd bought B&Q owner Kingfisher (LSE: KGF) is 2007 believing the housing boom would continue, you'd follow housing news closely and may have seen your thesis falling apart -- forcing a timely sale. So, what's the thesis behind each stock you own? Write it down.

4. Better Places for Your Money

Sometimes a sell decision has little to do with the holding itself -- you may simply see better opportunities elsewhere and lack the funds to take advantage. Just as a football coach will swap tired players for fresh ones in order to win the game, your portfolio can benefit from shuffling some players, too.

Earlier in this decade, you may have noticed household goods company Reckitt Benckiser (LSE: RB) making good strides whilst growth at consumer goods giant Unilever (LSE: ULVR) was starting to slow down. Over the past 5 years, Reckitt Benckiser shares have gained 78% while Unilever has gained only 25%. That would have been a great swap.

I'm pleased to see an article on Exit Strategies, especially now we know that 'unconditional' Long Term Buy and Hold (LTBH) is fallable.

The four exit strategies documented in the article are good, but I'd like to add...

5) When the price is falling.

Maybe this is not one for the Fools, but it would have gotten you out of the banks in 2007 at a time when the fundamentals still appeared sound to many observers.

The Titantic was a very sound ship -- unsinkable, they said. But the rising water level was the best early indication that it was sinking, long before the engineers analysed the design retrospectively and found it to be fundamentally flawed after all.

Hi lotontech, when the price is falling...how much does it have to fall by to make the Sell decision?

Fingered - a sensible stop loss - which all investors should have, but few seem to have - might be to sell when the price has dropped 15%

Fingered: that's the million dollar question isn't it?

Personally I would 'position trade' it. Set a tight stop order initially, in case I was wrong at the outset. As the price rose, I would raise the stop but widen it so as to secure some of the profit while leaving plenty of wriggle room for corrections. I would hope to hold forever -- just like Warren Buffett -- and would collect dividends along the way, but I would not argue with my stop order once it triggered. I would trail my stop manually, respecting any obvious support levels, rather than relying on a fixed percentage automated trailing stop.

Although I am an advocate of Stop Orders, which are technical in nature, it doesn't rule out (as per the original article):

1) Choosing the stock in the first place based on some fundamental 'value' judgement.
2) Exiting prematurely on some 'over-value' or 'better invested elsewhere' judgement.

So whereas I chose the Titanic (stock) based on its solid design, and I will get off when I reach my destination (or profit target), I have my lifeboat (stop order) ready for when the ship starts sinking for no apparent reason.

Tony.

- You need the money.

- You're selling each year a quantity exempt from CGT.

- You're rebalancing after something has become overweight.

- You're keen to avoid becoming a majority shareholder.

If you buy on sound fundermentals and then sell 15% lower without the story changing, won't you immediatly repurchase on the sound fundermentals?
How can loosing 15% on even the good companies be a rewarding strategy?
Why is where you brought it important? - why not sell if it's fallen 15% since the last full moon?
