Brad here. One of the great things about Commonwealth is that we have a team of expert analysts to provide valuable context on pretty much anything we need. Today’s post, from Nathan Parker, highlights the evolving energy landscape in the U.S. We must understand where we came from to know where we are going, and this is a great read that does just that for the energy sector. Over to you, Nathan.

It was the best of times, it was the worst of times. Catchy beginning, yes? Dickens certainly used it to good effect. As I was thinking about 2017 in retrospect, it seemed almost unavoidably appropriate.

Yesterday, we talked about some of the current economic trends that have carried the markets up but that may be shifting in the near term. Indeed, those negatives are potentially very real, and we need to keep an eye on them. But there are also several emerging positive trends that are likely to show up in the next 5 to 10 years that should help us ride out those changes. Consider this the Tigger response to yesterday’s Eeyore message.

I have been wrestling with what to write about today. There’s not much to add that is new. The economy is doing well, and the data is coming in strong. Although the stock market is reacting to events in Washington, it is still within 1 percent of its all-time highs. From my beat, there is not a lot worth commenting on at the moment.

I am really coming to grips with my 2018 outlook, and I find myself wrestling with the implications of slowing growth on the economy and, in particular, the markets. The fundamentals have been strong, with good earnings growth driving the markets up. The other major factor has been confidence, both business and consumer, which (despite everything) has been rising. Typically, rising confidence drives stock market multiples higher—and that is exactly what has happened this year. So, the great market results we’re seeing have been the result of a double whammy: improving fundamentals as confidence and valuations rise.

Right now, I am in the process of writing my monthly market update. While reviewing the data, the markets, and so forth, something just hit me: things are actually really, really good! We don’t normally get this much positive news all at once or for such a long time. We are living in the sweet spot.

Sitting in the chair that I do, I take quite a bit for granted, not least of which is that things I deal with every day—for example, the Fed—are important. Yet when you stop and look at it, if you are not in the middle of the financial news flow, it isn’t obvious (at least it wouldn't be to me) exactly why that is. Why is there so much coverage of Fed meetings and, at the moment, the selection of a new chair to run the Fed? Today, let’s take a step back and think about why the Fed matters to you and why you should care.

In part 4 of this series, we concluded that the map was separating from the territory, along with the reasons why that was so. Today, let’s take a look at what to do about it.

As I mentioned yesterday in part 3, passive investing is a rule-based system and a fairly simple one. Put your money into an index, and buy all of the components at the current weight. This is the case regardless of whether you purchase a mutual fund, ETF, or some other vehicle. You simply buy the index, taking its weights as gospel.

Last Friday, we talked about how artificial intelligence (AI) is, at heart, something simple: a set of rules and if-then statements. As such, AI can be very helpful in a simple environment, where relationships and rules remain constant, but it tends to stumble when those rules change. Waze, which is a great example of this, lives in a world of maps. It is very useful, but it fails when the reality doesn’t match up with the map. Any self-driving car will have to take closed roads, weather, and crazy drivers into account, which works well much of the time, but not always.
