How often should we rebalance our portfolio? – SWR Series Part 39

August 5, 2020

In the 3+ years, while working on the Safe Withdrawal Rate Series, I regularly get this question:

What’s my assumption for rebalancing the portfolio?

In the simulations throughout the entire series, I’ve always assumed that the investor rebalances the portfolio every month back to the target weights. And those target weights can be fixed, for example, 60% stocks and 40% bonds, or they can be moving targets like in a glidepath scenario (see Part 19 and Part 20).

In fact, assuming monthly rebalancing is the numerically most convenient assumption. I would never have to keep track of the various individual portfolio positions (stocks, bonds, cash, gold, etc.) over time, but only the aggregate portfolio value. If the portfolio is rebalanced back to the target weights every month I can simply track the portfolio value over time by applying the weighted asset return every month.

But there are some obstacles to rebalancing every single month:

  1. It’s might be too much work. Maybe not necessarily the trading itself but keeping track of the different accounts and calculating the aggregate stock and bond weights, potentially making adjustments for taxable accounts, tax-free and tax-deferred accounts, etc.
  2. It might involve transaction costs. Even in today’s world with zero commission trades for ETFs, you’d still have to bear the cost of the bid-ask spreads every time you trade.
  3. Even if you hold your assets in mutual funds (no explicit trading costs) there might be short-term trading restrictions prohibited you from selling and then buying (or vice versa) too frequently.
  4. It might be tax-inefficient. If an asset has appreciated too much you might have to sell more of it than your current retirement budget to bring the asset weight back to target. But that would mean you’ll have an unnecessarily high tax bill that year. Of course, this tax issue could be avoided by doing the rebalancing trades in the tax-advantaged accounts, not in the taxable brokerage accounts.

And finally and maybe most importantly, there might be a rationale for less-than-monthly rebalancing: it might have an impact on your Sequence of Return Risk. So, especially that last point piqued my interest because anything that might impact the safety of my withdrawal strategy is worth studying.

So, on the menu today are the following questions:

  • Under what conditions will less-frequent rebalancing do better or worse than monthly rebalancing and why?
  • How much of a difference would it make if we were to rebalance our portfolio less frequently?
  • Could the “right” rebalance strategy solve or at least alleviate the Sequence Risk problem?

When Can We Stop Worrying about Sequence Risk? – SWR Series Part 38

July 15, 2020

Welcome back to a new installment of the Safe Withdrawal Series! If you’re a first-time reader, please check out the main landing page of the series for recommendations about how to approach the 38-part series!

I’ve been mulling over an interesting question I keep getting:

Is there a time when we can stop worrying about Sequence Risk?

In other words, when is the worst over? When are we out of the woods, so to say? A lot of people are quick throwing around numbers like 10 years. I would normally resist giving a specific time frame. The 10-year horizon indeed has some empirical validity, but I also want to point out a big logical flaw in that calculation. Nevertheless, in today’s post, I want to present three different modeling approaches to shed light on the question. And yes, I’ll also explain what the heck that Mandelbrot title picture has to do with that! 🙂 Let’s take a look…

My Thoughts on the “Passive Investing Bubble”

July 1, 2020

One question that I frequently get – in the comments section, via email and in-person – is whether the continued shift away from active stock picking and into passive index investing is all going to create one big, scary bubble. Will this all end in tears? As a member of the FIRE community and a lifelong true believer in passive indexing, it definitely piqued my interest when I heard that I’m (partially) responsible for increasing market inefficiencies and dislocations and potentially even a bubble.

The issue of the “passive investing bubble” bubbles up, so to say, with great regularity. An example is the August 2019 Bloomberg piece “The Big Short’s Michael Burry Sees a Bubble in Passive Investing” likening the current state of the equity market to the crazy CDO market right before the 2008/9 meltdown. Well, that definitely got everyone’s attention! Especially during the slow months in the summer when there isn’t much else going on and financial journalists have to come up with some eye-catching headline!

Long story short, I find that this a bunch of mumbo-jumbo. And instead of replying via email about 10 times a year I just decided to write a blog post about this topic, so I can point to this post in the future if there are people still wondering about my views. That saves me a lot of time and I get to distribute my view to a larger audience, just in case other readers had this same question. And I get into the details a bit more than in a short email reply.

So, why am I not too worried about this shift to passive indexing? Let’s take a look…

Are we in another Bull Market now?

May 11, 2020

The stock market is still well below its February all-time-high, but it’s holding up remarkably well considering how poorly the economy is doing right now:

  • Double-digit unemployment,
  • 20+ million jobs lost according to the BLS payroll employment data,
  • 30+ million jobs lost according to the sum of weekly unemployment claims since March,
  • -4.8% GDP growth in the first quarter (annualized rate) and possibly a 10% drop quarter-on-quarter in Q3, which would be reported as a 34% drop annualized!
  • And a whole host of other economic indicators that look so bad, you’d have to go back to the Great Depression to find similar readings

Actually, “holding up” is a bit of an understatement when you look at the stock market as of the Friday, May 8 close:

  • The S&P 500 TR index rallied 31% since the March 23 low!
  • We’ve recovered more than half of the drop peak to trough!
  • Since April 8, we’re no longer 20% below the recent all-time-high, which is often quoted as the cutoff for the Bear Market!
2020 Case Study
The 2020 Bear Market up to May 8. Did a new Bull Market start on 3/24?

Does that mean the Bear market is over now? I certainly hope so! Whether the Bear Market is over and a new Bull Market might have started already obviously depends on the definition of Bull vs. Bear. What is that definition of Bull vs. Bear anyway? Different people have different definitions, some more sensible than others. And it gets more complicated: even if we do agree on a sensible definition, there could still be uncertainty over what’s the state of the market right now because some criteria cannot designate the state of the world in real-time but only after the fact. There’s a confirmation lag! So, we could be in a sort of a bull/bear-limbo state right now! How is that possible???

So many questions! Let’s take a look at how I think about Bull vs. Bear…

Three Equity Investing Styles that did OK in 2020

April 22, 2020

Recently, I wrote a post endorsing the simple Bogleheads approach: invest in passive index ETFs. Everything else is just mumbo-jumbo, window-dressing and people not understanding the (mostly) efficient market nature of the stock market. In other words…

Simple (indexing) beats complicated active investing

Well, after unloading on some of the fancy complicated investing styles, I just like to point out the select few of them that indeed performed relatively well in 2020. At least better than the index. So, for the record, I’d also like to write about three examples where…

Complicated beats simple index investing

And most importantly, I’m not pulling some “Monday Morning Quarterback” nonsense telling you that if you could have sold your airline stocks in February and replaced them with stocks for video conferencing makers you could have done really well. Well, duh, very few people other than U.S. Senators had that kind of inside information back in February! Rather, I want to write about some of the deviations from simple indexing that were mentioned here on the blog in my posts and/or in the comments. Before the crisis!

Some Financial Lessons from the First Quarter of 2020 (incl. Jack Bogle’s Revenge)

April 8, 2020

Wow, we made it through the first quarter of 2020. Seemed like an eternity! Remember January 2020? Suleimani Drone strike and an almost-war with Iran? Australian Wildfires? February? The Super Bowl, the impeachment trial? Even early March: Super Tuesday (March 3). It all feels like years ago! All those daily 100-point S&P 500 and 1,000-point Dow Jones moves took a toll. They make you age in dog years, I guess!

Time to look back and reflect. Let’s take a look at a few lessons I learned… Continue reading “Some Financial Lessons from the First Quarter of 2020 (incl. Jack Bogle’s Revenge)”

Some Random Thoughts on the State of the World

March 27, 2020

Wow, I’m in a writing mood these days. A second post this week! Here are a few random thoughts about the current situation. All the things on my mind right now that might be too short to put into a separate blog. Since you’re likely all sitting at home feeling bored, I thought you might enjoy this… Continue reading “Some Random Thoughts on the State of the World”

Dealing with a Bear Market in Retirement – SWR Series Part 37

March 25, 2020

In my post last week, I looked at how the 2020 Bear Market will impact folks saving for (early) retirement. But I deferred my recommendations on how current retirees will optimally adjust to the new realities. So, here we go, a new installment of the Safe Withdrawal Series, now 37 posts strong!

Nothing I write here today should be shocking news to people who have read the other 36 parts, but having it all summarized in one place plus some new simulations and perspectives is certainly a worthwhile exercise. In a nutshell, I argue that if you’ve done your homework before you retired, not even a bear market, not even this bear market will derail your retirement. Depending on what approach people chose, some retirees might even increase their spending target now.

Let’s take a look…

It’s a Bear Market now, all right! But what kind of bear will it be?

March 18, 2020

Well, there you have it! Just after I wrote a post two weeks ago pointing out we hadn’t even reached a Bear Market yet, all major U.S. indices, including the S&P 500 and the Nasdaq Composite tanked and fell into Bear Market territory last week and even touched the -30% mark after the precipitous fall on Monday. 

So, it’s a Bear Market now, all right! But not all Bear Markets are created equal. Which begs the question…

What KIND of bear will this be?

A little cuddly Panda Bear like in the picture above? Or the fearsome Grizzly Bear? Here are some of my thoughts and reflections on the Bear Market…

Safe Withdrawal Math with Real Estate Investments – SWR Series Part 36

Welcome to another installment of the Safe Withdrawal Rate Series. This one has been requested by a lot of folks: Let’s not restrict our safe withdrawal calculations to paper assets only, i.e., stocks, bonds, cash, etc. Lots of us in the early retirement community, yours truly included, have at least a portion of our portfolios allocated to real estate. What impact does that have on our safe withdrawal rate? How will I even model real estate investments in the context of Safe Withdrawal and Safe Consumption calculations? So many questions! So let’s take a look at how I like to tackle rental real estate investments and why I think they could play an important role in hedging against Sequence Risk and rasing our safe withdrawal rate…
