You've probably heard this axiom before: "The definition of insanity is doing the same thing over and over again and expecting a different result."

Such a sage principle of life is especially true when it comes to investing.  Stock and bond markets are places where millions of different traders meet each day to agree on a price that both buyers and sellers can find acceptable — i.e., fair.

"No single trader can know more than or have a consistent advantage over the millions of other market participants around the world," noted Mark Hebner in his book "Index Funds: The 12-Step Recovery Program for Active Investors." He added: "Markets are likely to reward long-term investors, not short-term speculators." 

The IFA Founder and CEO characterizes those who think they can consistently beat such odds as "time pickers." Hebner wrote:

"Time pickers or market timers claim the ability to predict the future movement of the stock market, moving into the market before it goes up and getting out before it goes down. However, numerous studies from industry and academic experts demonstrate market times have no such ability to beat the market, and they should be avoided just like the lion's cage at (P.T.) Barnum's circus." 2

How harmful can mistiming markets be to your portfolio? The chart below illustrates hypothetical data related to the impact that missing a few of the market's best-performing days can have on long-term returns. While this data provides insight into the benefits of remaining invested in the stocks comprising the IFA SP 500 Index, it is important to note that these figures are based on hypothetical modeling and may not reflect actual market conditions or future outcomes. Key takeaways from such research included:

  • A hypothetical $1,000 turned into $7,135 from 2005 through 2024.
  • The return dwindled to $3,271 if you missed the blue-chip index's 10 best days.
  • Missing the best 20 days resulted in your return dropping to $1,967.
  • Staying invested throughout this period would've returned an annualized 10.32%.

The lesson here: A strong correlation generally exists between time invested and growth of wealth.

As a result, IFA offers clients complimentary holistic financial planning on an ongoing basis. We've also developed a range of different financial calculators and educational resources to help make sure you remain on-track in achieving your holistic financial goals over the long haul.. These are tools designed to assist in long-term planning, but they do not replace individualized financial advice tailored to specific needs (These can be found by clicking different icons listed at the top of IFA.com.)
