After last week’s series about how I invest, a reader raised an excellent point with respect to passive investing. With all of the flows into passive strategies—pushing many stocks higher without regard to their individual merits—is it a safe time to go passive?

Last week's economic news was all about whether there are signs of a rebound after a weak first quarter. This week will be a slow one, but the releases we will see are important.

After going through my investment thought processes over the past couple of days, today I am going to outline—in general—what I actually plan to do with my excess cash. So, let’s revisit some of the ideas we’ve talked about this week.

On Thursday, I appeared on CNBC's Power Lunch to discuss the current state of the market, rising rates, and investor skepticism. Overall, things are good, so how much better can they get? Listen in to learn more.

We closed yesterday’s post on whether markets are efficient with the conclusion that it could be possible to beat the market. But, to do so, we would need either better information or to view things differently—specifically referencing time horizons as one way to do that. Let’s start with a couple of areas where better information is a real possibility. Then, we’ll take a deeper look at the second idea, which is both more subtle and more interesting.

We closed yesterday’s post on how to invest with the question of whether markets were efficient—and what that would mean for how we invest. A foundational assumption of most investment theories is that markets are efficient, which is to say that all information is reflected in an asset’s price. If this holds true, then it shouldn’t be possible to beat the market because—by definition—everything that could affect prices is already accounted for.

Given what I do all day, you might imagine I have this investing thing all figured out. In fact, I probably wrestle with it more than most people. Part of what I do is think about many different types of investments and strategies. With all of those options in my head, it can be hard to make decisions about what is best, for me, at any given time and situation. Right now, for instance, I am in the process of putting what is (for me) a largish amount of cash to work. Do I buy in, despite my concerns about valuations? Do I wait and forgo any interim returns? If I decide to buy in, what should I buy?

Last week was largely focused on prices, although we got a look at consumer confidence. This week, we’ll be watching the economic data to see whether earlier signs of a slowdown are passing.

After writing yesterday’s post on the price of oil, I thought it might be useful to take a longer-term look at the behavior of oil. I think this will provide some context to yesterday’s discussion, as well as to future developments. To start, let’s look at the price history over the past 30 years.

Oil has been in the news quite a bit recently. Prices have risen to multiyear highs, and the recent decision by the U.S. to reimpose sanctions on Iran has rattled markets even further. We know that oil prices are a key risk indicator for the economy, but is it time to start worrying? Plus, what do higher oil prices mean—if anything—for the financial markets?
