Mean Reversion

If our stock reverts to the mean, I don’t see that high-frequency trading matters.

I’m paraphrasing what many CEOs and CFOs believe. The market is complicated. There’s volatility. Trading is global. ETFs and derivatives probably affect volume. But I’m trading at a reasonable multiple of forward earnings, so who cares?

I hear that question sometimes. More often, reporters tell me they hear it from CEOs and CFOs. What difference does it make that 60% of my volume is the same shares trading over and over? So we had 7,800 public companies in the Wilshire 5000 in 1997 and now there are 3,600 in it. My stock trades at 16 times earnings. That’s about right.

So long as my house goes up in value, what do I care that people are getting these really ridiculous variable-rate, no-money-down mortgages for 125% of the home’s value, which means they’re financing the furniture over 30 years? What difference does it make to me? My house is still up 15% in value.

According to the ETF Industry Association, at July 2012 there were 1,486 exchange-traded products (ETPs), up from zero about 15 years ago, give or take, and fast approaching one ETP for every two stocks. The industry had net July inflows of $17.1 billion, mostly to equity ETFs. (more…)

Mad Scramble to Skirt the NBBO

NBBO would be a good name for a rock band. But it stands for “National Best Bid or Offer.” It also appears to be some kind of joke, because everyone tries to avoid it.

The NBBO stems from legislation passed in 1975 by Congress to create a national market system. If you’re already snoozing, you’ll miss the good stuff. You cannot make up stories like this.

Back in the 1900s, several cases involving the NYSE and other exchanges and their proprietary data reached the Supreme Court. In each, the Court held that exchanges possessed an undeniable right to their proprietary quotations.

In other words, where we take for granted now that quotes for stocks are as basic a right as breathing, it used to be that keeping those quotes secret was as basic a right as breathing. (Since our markets flourished then and gasp now, we’d be idiots not to wonder which approach was correct.) (more…)
