Does market timing work? Absolutely but with a catch!

Many people think that market timing works and believe that they can time the market bottom and market top. Does market timing work? I don’t know because I can’t predict the future. Will the market go up? Will the market go down? My guess is only 50% correct. Therefore, I continue to believe time in the market is far more important than timing the market

Most readers will remember what happened between February and March 2020. The market was firing on all cylinders, reaching an all-time-high around mid to late February. Then the coronavirus, or the COVID-19 global pandemic, took over the news. Amidst uncertainties, the global stock market tanked. The S&P 500 went from a high of 3380 to a low of 2304 in about a month, a loss of over 30%. People were freaking out, calling the end of the bull market and the start of an extended bear market.

Looking back, we know the bear market was short-lived. The bear entered the room quickly and exited just as quickly. 

But it is always easier to look back. 

How many readers remember what happened with the stock market on Christmas Eve 2018? In case you have forgotten, on Christmas Eve 2018, the major indexes in both Canada and US took a nosedive and many media outlets stated it was “The end of the bull market,” “Major market plunge,” “The end is near,” and so on.

Seeing some similarities between the two events? Sure, the time frame was different – the market drop lasted about a month while the drop of 2018 Christmas Eve lasted only a day. But after the drop, the market recovered and eventually went higher.

We can say the same with the Dot-com bubble, the financial crisis, etc.  

Unfortunately, many investors suffer from what I called “extreme short-term memory.” They can only remember major stock market events that happened about the last year or so ago. They forget things that had happened outside of that window.

So, rather than learning from history and learning from their mistakes, many investors repeat their mistakes, over and over and over and over. They keep telling themselves “next time” but when next time comes around, they make the same mistake again. 

Even though we are still in the global pandemic, the market seems to be going higher and higher. Yes, there’s light at the end of the tunnel, but who knows exactly when this global pandemic will end and when we can finally go back to the old normal. 

With the market hitting record highs, yet again, the following question is being raised:

The market is at its all time high, so I think the bear market is coming. Isn’t it a far better idea to sell stocks, take some profit, and wait on the sideline until the bear market has ended?

Does market timing work?   

A couple of years ago, I wrote a piece called “Does market timing work.” In it, I used 18 years of historical data from 2000 to 2018 and went through a few different scenarios to determine whether market timing works. 

There were a lot of numbers in that article and it was quite interesting for me to run the analysis. If you haven’t read the post before, I’d encourage you to read it before continuing with this article. 

In that article, I concluded that yes, market timing works but with an important caveat – hindsight is always 20/20. It is easy to use historical data to prove that market timing works. When we are in the thick of things, it is nearly impossible to know what’s going to happen to the market the next day. 

Let me bring up one of my all-time favourite quotes:

I can’t recall ever once having seen the name of a market timer on Forbes’ annual list of the richest people in the world. If it were truly possible to predict corrections, you’d think somebody would have made billions by doing it.

Peter Lynch

Yes, market timing in theory works. The problem is that no one will ever know when it is the right time to buy or sell in advance. Therefore, it makes the most sense to have a core investing strategy and stick with it. Get in line and stay in line, don’t jump around and change your core investing strategy.  

With all that said, I thought it would be interesting to do another market timing analysis by using historical data since January 2020 and create a few scenarios to see if market timing works or not. 

Before getting started, market timing doesn’t necessarily mean sell near the market high or buy near the market low. We as investors all deploy some sort of timing the market strategy. For example, if you regularly contribute and invest money and dollar cost average your cost basis, you are already timing the market. 

Does market timing work? – Background info

With the market drop of 2020 being fresh on peoples’ minds, I want to go through historical data and test if market timing works or not. For this exercise, I am going to rely on two ETFs that we own – the iShares all equity ETFs, XEQT, and the iShares ex-Canada ETF, XAW

Does market timing work - XEQT historical price
XEQT historical price

Both ETFs hold 100% in stocks, so they are vulnerable to any stock market movements. 

I will back test with two portfolios. Portfolio #1 will only hold XEQT and Portfolio #2 will only hold XAW. 

We would start with a portfolio value of roughly $70,000 at the beginning of 2020. Portfolio #1 with XEQT would start with 3,243 shares ($70,016.37 at $21.59 open price on January 2nd, 2020). Portfolio #2 with XAW would start with 2,492 shares ($70,000.28 at $28.09 open price on January 2nd 2020).


  1. I pulled historical price data from Yahoo Finance. I used the daily average as the purchase prices. 
  2. I ignored distributions/dividends to keep things simple. 
  3. Full shares (i.e. no fractional shares) to the closest dollar amount would be purchased each time. 
  4. No trading commission for buying and selling. 
  5. For market value, I used the closing price on April 1, 2021. 

The scenarios 

Here are six scenarios I came up with. We will assume that we have $70,000 to deploy throughout the time period. 

Does market timing work - XAW historical price
XAW historical price
  1. Purchased $70,000 worth of XEQT or XAW on February 12, 2020, the all-time-record high at the time.
  2. Purchased $70,000 worth of XEQT or XAW on March 23, 2020, the bottom of the market during the time period.
  3. Sold all the shares on February 12, 2020, then re-entered the market with all the cash on March 23, 2020.
  4. Sold all the shares on March 23, 2020, then re-entered the market with all the cash on September 23nd, 2020, after the market had rallied for roughly six months since the bottom.
  5. Purchased $5,000 worth of XEQT or XAW on the second Tuesday of each month starting in February 2020 and ending in March 2021, for a total of 14 purchases. 
  6. Purchased $35,000 worth of XEQT or XAW on the first trading day of July 2020 and the first trading day of January 2021, six months apart between the purchases.  

For scenario 1, I am simulating that we purchased at market high and seeing what happens if we don’t touch the portfolio at all.

For scenario 2, I am simulating that we can effectively time the market and purchase at the market bottom.

For scenario 3, I am simulating that we can time the market perfectly by selling everything at market high and buying everything at market low.

For scenario 4, I am simulating that we time the market completely wrong by selling everything at market bottom. We then sit on the sideline for six months before entering the market.

For scenario 5, I am simulating the dollar cost average strategy by deploying the same amount of cash each time on the same day of the month.

For scenario 6, I am simulating two lump sum purchases every six months. 

Results – XEQT

Below are the XEQT results for all six scenarios:

Scenarios# SharesBook ValueBook PriceMarket ValueProfit% Return

45,702$  121,595.15$       21.32$   142,036.82$  20,441.6716.81%

66,404$  139,998.29$       21.86$   159,523.64$  19,525.3513.95%

As expected, Scenario #3, where we sold high and bought low had the best return at 56.52%. If you could perfectly time the market, you would have done extremely well. 

And if you could have known that March 23, 2020 was the absolute bottom of the market, and deployed all your cash on that day, you would have done well, as we see in Scenario #2. 

What I found particularly interesting is when comparing Scenario #1 and Scenario #4. In Scenario #1, we purchased $70,000 worth of XEQT at the high of the market. Despite this perfect wrong timing of the market, on April 1, 2021, we ended up with a market value of over $158k, a profit of over $18k, or a return of 12.87%. Not too shabby! 

In Scenario #4, although we sold everything at the market bottom, then re-entered the market after sitting on the sideline for six months, we ended up with a market value of over $142k, a profit of over $20k, or a return of 16.81%. Again, a decent return! 

In Scenario #1 and #4, despite the terrible market timing, we ended up with a decent profit. I don’t think anyone would complain about a +10% return in roughly 15 months. Sure, you’d have underperformed compared to the market, but a +10% return is a lot better than putting all your money in a high savings account, earning 1% interest. 

Scenario #5 simulated a dollar cost average strategy, while Scenario #6 simulated a lump strategy with two purchases. Interestingly enough, we ended up with very similar performance between these two scenarios with a final dollar difference of only $1,145.86 or about a 0.7% difference.  

  • Scenario #5 – $160,669.50. Profit of $20,774.88.
  • Scenario #6  – $159,523.64. Profit of $19,525.35.

Should you make a lump sum purchase or spread your purchases over a set time period? I think this totally depends on what kind of investor you are

What if you sold everything at the bottom of the market and sat on the sideline ever since? You’d end up with $121,612.35. Way worse than any of the scenarios we have covered.

Once again, this proves that time in the market is far more important than time the market. If you are invested in the market, at least your money is working hard for you. 

Results – XAW

Below are the XAW results for all six scenarios:

Scenarios# SharesBook ValueBook PriceMarket ValueProfit% Return
1    4,894$  139,994.56$    28.61$  158,859.24$  18,864.6813.48%

6    4,917$  139,963.06$    28.47$  159,605.82$  19,642.7614.03%

Once again, we saw very similar behaviours as XEQT results, the perfect market timing of Senario #3 came out way ahead of the other scenarios. 

Buying $70,000 worth of XAW at the peak of the market on March 23, 2020 and leaving everything untouched would return 13.48% in roughly 15 months, which is pretty decent. 

Even if you sold everything at the market bottom then bought back six months later with an additional of $70,000, you would have done pretty well, resulting in over $20k of profit or a return of over 16%.

Once again, there wasn’t a significant difference between spreading purchases over 12 months and two lump sum purchases. The difference is even smaller than the one we saw with XEQT with a dollar difference of $1,009.42 or roughly 0.6%. 

Further analysis

XEQT is an all-equity ETF that holds 100% in stocks. On the other hand, XAW is an ex-Canada index ETF that also holds 100% in stocks. XEQT has about 24% exposure to the Canadian market and about 47% exposure to the US market. XAW does not have any Canada exposure but has around 56% exposure to the US market. Given the similar compositions, it shouldn’t come as a surprise to see similar performance between the six different scenarios.

For the analysis above, we started with a portfolio of $70,000 and added $70,000 at different times of the year. The initial $70,000, at roughly 50% of the final portfolio value, probably dampened any market timing affects. What happens if we run the analysis again with only a $70,000 deployment in the six scenarios? 

Note, since there’s no initial $70k, scenario 2 and 3 are identical. 

Let’s recap the modified scenarios:

  1. Purchased $70,000 worth of XEQT or XAW on February 12, 2020, the all-time-record high at the time.
  2. Purchased $70,000 worth of XEQT or XAW on March 23, 2020, the lowest point of the short bear.
  3. Same as Scenario #2.
  4. Entered the market with $70,000 on September 23nd, 2020, after the market had rallied for roughly six months since the bottom.
  5. Purchased $5,000 worth of XEQT or XAW on the second Tuesday of each month starting in February 2020 and ending in March 2021, for a total of 14 purchases. 
  6. Purchased $35,000 worth of XEQT or XAW on the first trading day of July 2020 and the first trading day of January 2021.

Once again, Scenario #2, where we timed the market perfectly came out ahead. Scenario #1, where we purchased at the peak of the market provided a return of over 10% for both XEQT and XAW. 

What is quite interesting is that the dollar cost average strategy, Scenario #5, came out ahead of the lump sum purchases strategy, Scenario #6. The difference was roughly 1.5%. Meanwhile, if we had waited on the sideline for six months before deploying the $70,000 (Scenario #4), we would have performed better than Scenario #5 and #6. 

In other words, based on simulations I ran, there is no concrete conclusion that dollar cost averaging is better than lump sums. This further reinforces my belief that time in the market is far more important than timing the market. 

What should you do as an investor? Know thyself. If you sleep better at night by doing a lump sum purchase, go with that. If you sleep better at night by spreading your money across a set period, go with that. 

The vital point is to stick with your strategy!

Does market timing work? Absolutely, but with a catch! 

So, does market timing work? Absolutely! But there’s a catch – it only works if you can know when the peak and the bottom of the market are. It is significantly easier to use historical data to prove that market timing works. 

However, I don’t care if you’re the second coming of Warren Buffett, Peter Lynch, Benjamin Graham, Cathie Wood, or Carl Icahn. I can say with 100% certainty that you absolutely can’t predict the market peaks and bottoms.

Since my guess on how the market will do the next day, the next day after that, and so on, is as good as yours – and at best our guesses are only 50% correct, it is far better to stay invested and to invest with new capital regularly. 

By investing regularly it can mean investing in lump sums whenever you have money to stay fully invested, or invest the same amount regularly. Or you can deploy a combination of the two strategies and have some small amount of cash on the sideline, ready to deploy whenever there’s a sudden drop in the market.

For example, throughout 2020 we added over $115k worth of dividend paying stocks, $28,000 of that was from the sale of various dividend stocks and around $20,000 was from closing out of our kids’ dividend portfolio with ShareOwner. This meant we added around $67,000 in new capital to our dividend portfolio in 2020.  

At the time of the writing, our dividend transactions are up by over $23,000, or 20% return. We have kept our investing strategy as simple as possible. For the most part, we stay fully invested by not touching our dividend portfolio. Whenever we have cash from savings, we deploy it and purchase dividend paying stocks. So far, this strategy has worked marvelously well. 

Whatever you decide to do, it is best to stick with the same strategy. And remember, it is best to keep your investment strategy as simple as you can. 

How simple? Simple enough that you can explain to a three-year-old.  

So, stop worrying about whether the market has peaked or not. Stop wondering when the market bottom is. 

Stay invested and let your money work hard for you.

  1. Hindsight will always be 20/20. What’s crazy is how much of a genius and rich someone will be if they just saw the future with perfect accuracy by a single second.

    Because we don’t really see genius day trading market timing record in the real world, it’s safe to assume no one has that capability (yet).

    It’s just crazy to know how advantageous just being ahead by a single second is.

  2. I timed it pretty well last year. We were a bit overweight with bonds (30%) because I thought the market was too high. When it crashed, I moved in gradually and now we have just 10% in bonds. It worked beautifully.

    However, this is what nobody tells you. The 30% bond was sitting around earning very little for a couple of years. If I put it in the market in 2018, I’d probably get a very similar end result. Timing the market is stressful and rarely works. Most investors just aren’t quick or knowledgeable enough.

    Now, I think I’ll leave our bond allocation at 10% until we’re older. No point messing around. Although, the market is getting pretty high right now….

  3. It is obvious that no one can predict market tops or bottoms. I am not disputing that at all.

    However, I also believe we must not forget that some bear markets in the past did last more than one decade, e.g. i) the 1929 crash took until 1953 (24 years) before S&P went back to even; ii) the 1967 crash took until 1990, 23 years, before S&P went back to even; iii) the 2000 crash took until 2014, 14 years before S&P went back to even.

    One therefore has to know his/her own investment objectives and investment time spans before putting any money at risk. Yes, all bear markets have historically gone back to even or better, but do you have 24, 23 or 14 years to wait for your investment returns? Worse, you may need to access the capital long before that, never mind any returns.

    Personally I am tiptoeing into our Canadian dividend-yielding companies with only 1/4 of my allocated amount and only into the few names with relatively low current valuation (cheap), e.g. Alqonquin and Centerra Gold. I will release the other 1/4s when I see ‘blood on the street’, i.e. crash.

    I wish investing were as simple as the media has been telling us: put in your money over a long enough period of time and the pile will just grow and grow and we will be in monetary heaven whenever we are ready to retire. That is: stock market may have minor corrections from time to time but it will always go up at the end.

    • It would be interesting to back check those years too but this kind of exercise is extremely time consuming. 🙂

      Knowing your investment timeline and your risk tolerance is extremely important.

      • Reading this post belatedly after reading the 2021 year end summary post.

        Very interesting how you ran a simulation 🙂 can you do that in 2022 as well and make it an annual series?

        For me, 2021 is the first time that I became serious about investing and went beyond the Big 5 banks’ mutual fund schemes. I have yet to fully invest in dividend stocks but most of my portfolio is in dividend stocks.

        In my current infancy as an investor, I have been mixing both dollar cost averaging and lump sum investment and I think that has worked well for me. Oh and using Norbert’s Gambit to first convert my CAD into USD has had an unexpected effect of forcing me to slow down and not buy as knee-jerk reaction haha.
        I have luckily “timed” the market by buying AQN cheaply and then selling right before it fell. I think that was totally a beginner’s luck and I think in general “time in the market” is better (I learned it the hard way by selling COST & QCOM too early boooo) That said, I think I am a fan of discounted stocks so I recently started to watch the market for specific stocks I want and buy only when the drawdown is -15% or more. While I intend to be a long term investor and not sell (again QCOM and COST taught me tough lesson), I think it is nicer to buy when things are cheaper than their highest price of the year and hold cash and wait. I may change my strategies in the future, but for now, my hybrid dollar cost averaging has been working alright this year 🙂

  4. Bob,

    Another great post. I am not altogether a believer in market timing however I feel that a smart strategy is important to getting the best result possible from market timing your buys. You have to have a certain amount of cash available at all times to take advantage of market corrections and you can get this from many places, most importantly trimming your overweight positions to re-allocate and new money added to your portfolio.

    Here is somewhat what I do, and for fun, lets use the number of $50,000 in cash I have available to use for adding to my core positions. Keep in mind, I am buying my core stocks and etf’s which represent the best of breed companies that are caught up in a sell off, not because the companies had poor fundamentals.

    1. Market drops 5% to 10% – I deploy only a portion of my cash, ie: maybe 25% of it.. $12,500 to add to my positions.
    2. Market continues to drop lower another 5% to 10% – I deploy another 25% of it. $12,500 adding to my positions.
    3. Market continues to drop lower another 5% to 10% – I deploy another 25% of my cash and so on etc.
    4. If I have more cash than the original $50,000 I can deploy larger buys as the market drops further. Better to buy more when the markets have already dropped 30% to 40% already as opposed to when they have only started to drop and are down 10% only.

    I never actually buy the bottom, but I can try to dollar cost average average my way into it and hope I can get as close as possible with my cost base’s lowered by my strategic buys.

    This has worked for me over time, you just have to always be ready for a downturn with some dry cash. There are lots of places to hold 10% to 15% of your portfolio so it is liquid and ready for deployment that will pay you a decent dividend.

    This is a small part of my buying strategy, hope it is helpful in some way to others. Good luck!


  5. Excellent read! We cannot predict market movements. It’s simply impossible. So, it’s paramount to stay invested, dollar cost average, focus on quality and the business fundamentals. Over time, the compound effect is amazing.

  6. Great post Bob! Indeed I have this exact same problem — I can’t accurately predict the future, so I can’t time the market! I have no idea if stocks are going to go up or down on any random day!

    Instead, I try to focus on compounding capital at good rates of return, and try to ignore the wiggles and wobbles of the market.
