There can be good reasons for selling investments, but hoping to time a price peak isnt one of them.
American financier Bernard Baruch made a fortune in the stock market during the early 20th century. When asked the secret of his success, he is said to have replied, I always sold too early.
Its a clever lineso clever that commentators unfamiliar with Baruch occasionally attribute it to Warren Buffett. But it reminds us that market timing has always been a tricky business. Investors tend to get emotional when they see highs and lows in the marketselling on impulse, rather than strategy, and thinking they can time the market.
If the takeaway for you is that you should hone your market-timing skills, you should think again.
For decades, research has shown that emotionally driven trading leads to a huge gap in investor performance. The classic A Random Walk Down Wall Street popularized the buy-and-hold approach to avoid market timing mistakes in 1973. As proven time and again, vigorous trading to catch the market at just the right moment is one of the worst things an investor can do.
The Good Reasons to Walk Away
There can be good reasons to walk away from an investment, but hoping to time a price peak isnt one of them.
The real reason to sell and switch investments is to move into something better. The question to ask before selling an asset is, what am I going to replace this with?
It can be worthwhile to sell a mutual fund, especially one intended to be a core, long-term holding, if its management fee and other expenses are higher than those of similar funds with the same investment objective. Replacing it with a cheaper, more diversified, and more tax-efficient mutual fund or ETF can make a lot of sense.

But chasing short-term performanceanother way to say selling recent losers and buying recent winnersis always a bad idea. Lets look at data from Morningstar. A recent winner, a fund whose performance put it in the top quartile in 2013 among portfolios with the same investment objective, had only a 56% chance of doing better than average in 2014, barely better than you would expect by random chance.
As for bottom-quartile funds, the recent losers, they outperformed only 48% of the time in 2014; again, not much different than flipping a coin. So the odds are you wont do meaningfully better or worse by chasing performance and switching investments, but youll be on the hook for tax on any capital gainpotentially taxed as short-term capital gainsthat you generate from selling the old fund.
Dont Let Emotions Drive You to Sell
Its important to note that a significant problem with the decision to sellespecially when its individual securitieshas nothing to do with costs, and instead has a lot to do with emotions.
Loss aversion, a well-known psychological behavior, is a way to say that we feel the pain of losing more strongly than we feel the pleasure of winning. Psychologists Daniel Kahneman and Amos Tversky first introduced this concept more than 30 years ago in a study, which built the foundation for what would become the field of behavioral finance.
The study found that loss aversion expresses the intuition that a loss of $X is more aversive than a gain of $X is attractivefor example, most respondents in a sample of undergraduates refused to stake $10 on the toss of a coin if they stood to win less than $30.
This indicates that the aversion to losing is so strong that people will knowingly leave money on the table in order to avoid a sense of loss.
This plays a big role in investor behavior; investors have a (bad) habit of selling winners and not letting losers go because of loss aversion, rather than for logical financial reasons. Realizing a gain feels good; we think we did something right and were rewarded for it. Realizing a loss can feel like we made a mistake and had to pay for it. Its easy to want to avoid taking the loss and hope that a losing stock will come back if only you hold on.
But theres a big problem with selling winners: taxes. A strategy of locking in gains and keeping losers is certain to be tax-inefficient, and it can easily produce worse after-tax returns. Reducing tax liability is always important, and even more so since 2013, when rates on capital gains went up and a new tax on investment returns was imposed on some high earners.
Another reason not to be eager to sell winners is that the trend can be your friend. Strong performers can keep rising, and it works in the other direction, too; assets that have lost value may continue to do so.
Hanging on to winners allows gains to accumulate and defers taxes on them, while selling investments that arent living up to expectations can prevent losses from mounting. Once they do mount, another quirk of human nature comes into play, one that Baruch alluded to: the tendency for stubbornness to give way to panic, leading investors to dump their holdings at a bottom.
Strategic Selling: Rebalance or Tax Loss Harvest
One of the few sensible reasons to sell winners is to rebalance your portfolio. Rebalancing involves disposing of portfolio holdings in asset classes that have risen in value, and using the proceeds to buy more of your asset classes that have risen less in order to restore a desired balance between stocks and bonds.
Without rebalancing, you can end up taking on much more risk as more volatile holdings (stocks) make up a greater percentage of your portfolio after a surge. Rebalancing can be done periodically, say annually or quarterly, or whenever allocations deviate from the desired mix by some set amount, say five percentage points in either direction. Yes, you are selling winners, but you are doing it as part of a rational and scheduled strategy.
The need to rebalance may be more acute after a significant run of outperformance by one asset class over the other. Automated investing services perform rebalancing automatically for investors. In fact, algorithms can precisely measure the drift from the ideal allocation and the tax cost of reducing that drift, and balance them down to the penny.
Tax loss harvesting is a good reason to sell a losing asset, provided you replace it with something that offers similar risk. At its most basic level, tax loss harvesting is selling a security that has experienced a lossand then immediately buying a correlated asset (one that provides similar exposure, ideally in the same asset class) to replace it. The strategy allows the investor to realize a loss, which can be useful to reduce or defer a tax liability, while keeping the portfolio balanced at the desired allocation.
Baruch became a Wall Street legend by making a killing in the stock market. He controlled risk and preserved his wealth by selling appreciated assets at more or less the right time. If you think you can match his results, good luckbut remember that few people have the time, knowledge, and luck to beat the market. Youre better off trying to achieve the same results by selling in a systematic, disciplined way to stay properly diversified.
