The past few weeks have been unusually turbulent. North Korea has tested what is reportedly a hydrogen bomb and launched a missile over Japan; as a result, the U.S. is openly considering war. Hurricane Harvey has been the most damaging storm ever, devastating both Texas and Louisiana. And now we have Hurricane Irma, the most powerful Atlantic storm in history, approaching Florida. Given these events, there are certain questions that investors should be asking themselves. That is, should we be doing something different? If so, what?

August was a solid month for the economy and financial markets. International markets were mixed, but U.S. markets were up across the board, despite rising tensions with North Korea and the effects of Hurricane Harvey. Plus, retail sales came back, employment grew, and consumers seemed willing and able to spend.

Early last year, I made a rather bold statement: the employment boom was on. I had been hinting at it well before that, but in April, I finally felt that I could make a good case. Now, more than a year later, concerns about the economy are rising. So, is the employment boom still on?

Eagerly anticipated by all, it’s time once again to award the Bubble of the Year statuette, affectionately known as “the Bubby.” The award is a long-standing tradition, dating from yesterday afternoon, when I spent some time contemplating the day’s bitcoin pricing. With bitcoin up roughly 50 percent so far this month—and increasing significantly during this past year—we must ask, “Is this a bubble?” And if so, “What exactly is a bubble?”

In thinking about the market over the past week or two, what has really struck me is how truly remarkable the market’s behavior has been. After the U.S. president implicitly threatened nuclear war, the market dropped, of course—but by less than 2 percent—and then it bounced back. Today, after CEOs from big-time companies essentially abandoned the White House, the market is down—but by less than 1 percent. We’ve seen more political drama in the past couple of weeks than we saw in years under some administrations—and the market is just sitting there. What’s going on?

Recently, many readers have asked me about where the market is, as they are worried about what to do with their portfolios. The gentleman behind the grill at the café where I get breakfast, who knows what I do, has the same questions for me. Advisors want to know what I think about gold as a risk reducer. Almost every day for the past couple of weeks, I have heard about the nervousness. People are getting scared.

Yesterday, I wrote about mistakes I’ve made in the past and how I am using that experience to avoid being as wrong—at least in the same way—in the future. So, you can certainly see why a book with “How Not to Be Wrong” as the title appeals to me. The subtitle, “The Power of Mathematical Thinking,” is also attractive, as math is one of the great organizing principles of my profession. On the face of it, this sounds like exactly what anyone in my position should be looking for.

I received a really interesting e-mail from one of our advisors the other day. He asked me to identify instances when I had been completely wrong about something, why I had made the mistakes, and what I had learned from them. He was looking for ways to better himself when it came to thinking about the future—a goal I totally endorse.

Last week, the only major economic report was on consumer prices, released on Friday. Overall, this month’s data suggests that inflation remains low but is not dropping further. Therefore, the Fed will remain watchful, and it isn’t likely to increase rates in September but may well start the balance sheet reduction program.

After three consecutive days of market declines fueled by tensions with North Korea, the major U.S. indices were up on Friday. Is recent performance simply normal market action, or is it a sign of something worse to come?
