Don't Lose Your Cool When the Market Is Hot

How do you keep a cool head in a market that's hot hot hot?

That's the question I posed to Morningstar.com readers in a Discuss forum conversation this past week. After all, investors often make their biggest mistakes at inflection points--either when the market is peaking or troughing. How, I wondered, had seasoned investors or savvy newbies learned not to get caught up in the euphoria and instead make decisions they would not regret at a later time?

Readers complied by sharing a host of behavior-management techniques, many of which fit in all types of market environments, not just strong ones.

I shared some of my own thoughts in this video (http://www.morningstar.com/cover/videocenter.aspx?id=620785).

'Take a Vacation So That You Don't Tinker So Much'
Tuning out the day-to-day noise and maintaining a dedication to a simple portfolio plan--rather than one that's cluttered up with lots of specialty items--were at the top of ColonelDan's list. "I've tried to learn from my younger days when I allowed the market to dictate my actions," this veteran poster wrote. "I now make moves based on my personal situation, keeping my approach simple and my focus on the long term. Translation: I'll make no moves based on today's market highs that in years to come will be seen as just normal market behavior."

Similarly focused on the long term is another investing (and military) vet, Taylor Larimore. This Boglehead wrote, "When I started investing in 1950 the S&P 500 was less than 20. Today it's more than 1,700 (not including dividends). I'll continue to follow Jack Bogle's advice: 'Stay the course.'"

To do so, posters advised, it's often best to back away from that portfolio rather than succumbing to the urge to make changes.

Juris2 noted, "This is the type of market and the time of year when I am most tempted to tinker. Perhaps one recommendation: Take a vacation so that you don't tinker too much."

Chief K said he purposefully takes a deliberate approach to making any portfolio changes to avoid rash decisions; his process encompasses a top-to-bottom financial review and plays out over several months. "The time delay is to ensure that I have ample opportunity to review my decisions," the Chief wrote. "It's hard to 'Stay the Course' if you find yourself changing your mind about where you are going."

ForrestGump agreed that having a well-articulated process is essential to not get swept up in market manias. "Have a plan or set of investment guidelines and stick to it. It takes emotion out of the equation and turns the process into something mechanical."
