What if You Only Invested at Market Peaks?

“Warren [Buffett], it strikes me that if you did nothing else you never sell. That is, if you can grit your teeth through and just disregard short-term declines in the market or even long-term declines in the market, you will come out well. I mean you just stick all your money in stocks and go home and don’t look at your portfolio you’ll do far better than if you try to trade it.”  – Alan Greenspan

Meet Bob.

Bob is the world’s worst market timer.

What follows is Bob’s tale of terrible timing of his stock purchases.

Bob began his career in 1970 at age 22. He was a diligent saver and planner.

His plan was to save $2,000 a year during the 1970s and bump that amount up by $2,000 each decade until he could retire at age 65 by the end of 2013 (so $4,000/year in the 80s, $6,000/year in the 90s then $8,000/year until he retired).

He started out by saving the $2,000 a year in his bank account until he had $6,000 to invest by the end of 1972.

Bob’s problem as an investor was that he only had the courage to put his money to work in the market after a huge run up.

So all of his money went into an S&P 500 index fund at the end of 1972 (I know there were no index funds in 1972, but just go with me here…see my assumptions at the bottom of the post).

The market dropped nearly 50% in 1973-74 so Bob basically put his money in at the peak of the market right before a crash.

Yet he did have one saving grace. Once he was in the market, he never sold his fund shares. He held on for dear life because he was too nervous about being wrong on both his sell decisions too.

Remember this decision because it’s a big one.

Bob didn’t feel comfortable about investing again until August of 1987 after another huge bull market.  After 15 years of saving he had $46,000 to put to work. Again he put it in an S&P 500 index fund and again he invested at a market peak just before a crash.

This time the market lost more than 30% in short order right after Bob bought his index shares.

Timing wasn’t on Bob’s side so he continued to keep his money invested as he did before.

After the 1987 crash Bob didn’t feel right about putting his future savings back into stocks until the tech bubble really ramped up at the end of 1999. He had another $68,000 of savings to put to work. This time his purchase at the end of December in 1999 was just before a 50%+ downturn that lasted until 2002.

This buy decision left Bob with some more scars but he decided to make one more big purchase with his savings before he retired.

The final investment was made in October of 2007 when he invested $64,000 which he had been saving since 2000. He rounded out his string of horrific market timing calls by buying right before another 50%+ crash from the credit blow-up.

After the financial crisis he decided to continue to save his money in the bank (another $40,000) but kept his stock investments in the market until he retired at the end of 2013.

To recap, Bob was a terrible market timer with his only stock market purchases being made at the market peaks just before extreme losses.

Here are the purchase dates, the crashes that followed and the amount invested at each date:

mkt timer

Luckily, while Bob couldn’t time his buys, he never sold out of the market even once.  He didn’t sell after the bear market of 1973-74 or the Black Monday in 1987 or the technology bust in 2000 or the financial crisis of 2007-09.

He never sold a single share.

So how did he do?

Even though he only bought at the very top of the market, Bob still ended up a millionaire with $1.1 million.

How could that be you might ask?

First of all Bob was a diligent saver and planned out his savings in advance. He never wavered on his savings goals and increased the amount he saved over time.

Second, he allowed his investments to compound through the decades by never selling out of the market over his 40+ years of investing.  He gave himself a really long runway.

He did have to endure a huge psychological toll from seeing large losses and sticking with his long-term mindset, but I like to think Bob didn’t pay much attention to his portfolio statements over the years.  He just continued to save and kept his head down.

And finally, he had a very simple and low cost investment plan — one index fund with minimal costs.

Obviously, this story was for illustrative purposes and I wouldn’t recommend a portfolio consisting of 100% in stocks of a single market like the S&P 500 unless you have an extremely high risk tolerance. Even then a more balanced portfolio in different global markets with a sound rebalancing policy makes much more sense.

And if he would have simply dollar cost averaged into the market on an annual basis with his savings he would have ended up with much more money in the end (over $2.3 million).

But then he wouldn’t be Bob, The World’s Worst Market Timer.

Lessons from Bob’s Journey:

  • If you are going to make investment mistakes, make sure you are biased towards optimism and not pessimism. Long-term thinking has been rewarded in the past and unless you think the world or innovation is coming to an end it should be rewarded in the future. As Winston Churchill once said, “I am an optimist.  It does not seem too much use being anything else.”
  • Losses are part of the deal when investing in stocks.  How you react to those losses is one of the biggest determinants of your investment performance.
  • Saving more, thinking long-term and allowing compound interest to work in your favor are your biggest accelerants for building wealth. These factors have nothing to do with picking stocks or a complex investment strategy. Get these big things right and any disciplined investment strategy should do the trick.

***Assumptions and disclaimers: This is fictional and is in no way how you should invest your money. It takes nerves of steel to hold 100% of your portfolio in stocks for decades on end. This is purely an exercise in the power of long-term thinking and compounding. I used the S&P 500 less a 0.20% expense ratio from the 1972 until 1977 when the Vanguard 500 Fund had its first full year. I used the Vanguard 500 Fund from 1977 on so these were actual results from a real fund, not purely hypothetical.

    You said “world’s” worst market timer, right? How did Bob’s distant relatives in Japan, Greece, Italy and Iceland fare?

    • http://www.awealthofcommonsense.com Ben

      Hopefully Bob’s cousins in those countries realized their stock markets made up a very small % of world stock mkt cap. Japan is currently under 10%, Italy is about 1% and Iceland is a rounding error while the US is close to 50%.

      We are lucky in the US that companies/mgmt/govt protect shareholders relatively better than other countries. We also have a much more diverse economic system and stock market industry make-up.

      Still, it’s a global economy today so those mkts are a great example for global diversification and the need to get rid of your home bias if you live elsewhere.

    Wonder what Bob’s annualized rate of return was.

    • http://www.awealthofcommonsense.com Ben

      It’s difficult to give a good answer because most of the mistakes and lost returns came from the opportunity cost of holding cash for the majority of the period.

      Compounding is the key here. For example, that initial $6K invested in 1972 grew to about $300K by 2013. I did calculate the S&P 500 from 1972-2013 and it was over 10%/yr.

      • bart@gmail.com

        The annualized return is easy to work out. We know the dates and $ amounts invested (whether they went into the market or the bank is not relevant). A simple IRR calc in excel gives the annualized rate of return as 7.3%. Still better than cash.

        A question – did you take dividends into account in the calc of $1.1m terminal value?

        • http://www.awealthofcommonsense.com Ben

          Yes, dividends included. I thought about doing an IRR calc. but it’s really misleading because of the nature of the timing of the CFs. It’s why I think a multiple of invested capital makes more sense here (roughly 5x).

          • bart@gmail.com

            If I understood the setup of your example, the cashflows are very regular – once per year Bob has an outflow of cash (starting at $2k and ending at $8k). When he switches the cash from bank to stock market is not an outflow. So in this case his total return over the 40 years of 7.3% pa is the most relevant number.

            I find multiple of capital can be misleading over long periods of time.

          • http://www.awealthofcommonsense.com Ben

            Yes, you are right. I was trying to make it too complicated. Good call.

          XIRR 10.95%
          12/1/1972 -$6,000.00
          8/1/1997 -$46,000.00
          12/1/1999 -$68,000.00
          10/1/2007 -$64,000.00
          12/31/2013 $1,100,000.00


          So the worst timer appears to be better.

          • http://www.awealthofcommonsense.com Ben

            Interesting. Thanks for running the numbers.

  • http://www.dividendgrowthstockinvesting.com Dan Mac

    Great story and illustration of the power of holding investments for the long term. Looks like Bob did really well despite his terrible market timing on the buy side.

    I recall back in 2007-2008 when the market was tanking everyone was panicking and selling out. While it was difficult to do psychologically, those who didn’t panic and instead kept investing ended up much better in the long run.

    • http://www.awealthofcommonsense.com Ben

      Thanks Dan. There are smart investors out there who can sidestep market crashes, but it’s extremely rare to get both decisions right. A consistent buying process is probably the best bet for the majority of investors out there. Not perfect, but much better than the alternatives.

  • JRF

    So assuming that you don’t sell, there is basically no point waiting for a ‘good time’ (whatever that means) to entering the market? Another way of asking is what if Bob had timed his purchases a bit better, like waiting for the correction before making his first purchase?

    • http://www.awealthofcommonsense.com Ben

      As I showed, Bob would have been better off with a simple dollar cost average on a periodic basis (weekly, monthly, quarterly, etc.). He would have done better timing his purchases, but no one can really do that very well and since the general trend in the markets have been up over time, you are much better off emotionally making periodic contributions instead of trying to time your buys. It’s an impossible game to play when you constantly have to try to guess when it’s a good time to get invested. Your time horizon matters too, but psychologically, a simple DCA to your set asset allocation is the simplest way to get market exposure without losing sleep at night.

    Hi Ben, inspired by your article, a blogger on the Spanish site Rankia did a similar analysis for many countries……and came to the same conclusion.


    He suggests everyone should read your article but many people there will not have sufficient English to do so.

    May I translate your article into Spanish and post it on Rankia?

    • http://www.awealthofcommonsense.com Ben

      Yesm the blogger actually sent me his article and I was impressed with the analysis and the outcomes.

      Always happy to spread the news…feel free to pe-post on Rankia and thank you for checking. Maybe send me a copy when it’s up so I can share?

  • Lawrence Humphrey

    Hi Ben, here’s my translation, hope it will be of use.


    With best wishes.

    Very misleading. Sure, if you also invest through the greatest bull market in history. That will overcome a lot of investing glitches.

  • Dan

    Furthermore, statistics show that the average investor invests at the wrong times. It’s very unlikely that someone who jumped into a hot trend with very high stock valuations would also have the patience to hold through a steep fall.
