How Long is the Long Term?

Everyone always talks about investing (and planning) for the long term. But they’re usually vague about what the “long term” actually means. Does that mean 5 years? 10 years? More? (Spoiler: the answer is definitely more). And frankly, talking about how you need to focus on the long term can feel like a bit of […]
Reverse Engineering To Desired Retirement Time Horizons

Using the portfolio return and volatility assumptions determined in Exhibit 1.1, we then reverse engineer fixed return assumptions and sustainable spending levels for a desired retirement time horizon and targeted probability of success. The investment portfolio is modeled using 100,000 Monte Carlo […]

What Does the GameStop Kerfuffle Mean?

It’s been a pretty wild ride with GameStop. But while there has been a lot happening, does it actually mean much? We’ve examined the details of what happened elsewhere, so I’m going to focus on some of the bigger questions that this whole affair raises, and specifically how this all impacts long-term investors. So let’s […]
What Happened With GameStop?

Is the Value Premium Pining for the Fjords?

There’s no magic formula for investing. The financial markets seem to take some sort of cosmic joy in bringing people back down to Earth. And it’s value investing’s turn – in fact, it’s been value investing’s turn for a while now. To put it mildly, this has been a rough decade and a half for value stocks.
Adjustments For A Conservative Return Assumption

Consider three scenarios: An individual investing a lump-sum amount for thirty years An individual saving a fixed percentage of a constant inflation-adjusted salary at the end of each year over a thirty-year accumulation period An individual withdrawing the maximum sustainable constant inflation-adjusted amount from a portfolio at the start of each year over a thirty-year […]
A Guide to a Conservative Return Assumption

A simple approach for building a financial plan is to decide on a rate of return for the investment portfolio and to plug that value into a spreadsheet to represent assumed asset growth. Historical data may be used to calculate historical average returns for different asset classes, which are then combined to create the overall […]
Planning For The Future – What About Bond Yields?

Adjustments for Current Bond Yields An important consideration is that current interest rates are lower than the historical averages. The historical average return is not relevant for someone seeking to estimate future market returns from today’s starting point.

What To Do When Markets Plummet – Investor Behavior Gap

Studies on retirement spending from investment portfolios typically assume that retirees are rational investors who rebalance right on schedule each year to their rather aggressive stock allocations.
