NEW YORK (TheStreet) -- Monday's trading action was a not-so-gentle reminder that volatility still exists. We've perhaps grown a bit complacent, because we have not experienced trading action like that in quite a while.
One way that I measure market volatility is the number of days that the S&P 500 rises or falls at least 1%. It's a fairly simple indicator for sure.
Year to date, there have been just 11 trading days when the S&P 500 has moved up or down at least 1%. Yesterday's 2.3% drop was the worst day for the index since June 1, 2012, when it fell 2.46%.
In truth, it was a bad day for our country in matters that are far more important than the markets. We were reminded, yet again, that we live in volatile times and that life is fleeting.
In terms of market volatility, it's easy to forget that it was not that long ago that markets were on a veritable roller-coaster ride. By April 15, 2008, the S&P 500 had already logged 32 days for the year when it gained or lost at least 1%.
In 2009, there were already 43 such occurrences by the same date, out of a total of 71 trading days. It seems astounding that just four years ago, by this date, the S&P 500 moved up or down at least 1% an average of three days per week.
Comparatively, we are in a period of relative calm, but we also know that can change on a dime. I don't pretend to know what's coming next, which is why it's good to have some dry powder.
During days like Monday, the smaller, lesser-known names typically get hit a lot harder than the blue-chips. My favorite index, the Russell Microcap, was down 3.8%.
Many stocks were hit even harder. NL Industries
There was little to be positive about Monday, but one small name that has been on my radar for quite some time put up some better-than-expected revenue results after the market closed. Automotive service and retailer Pep Boys
Pep Boys has had a rough ride in recent years; it was less than a year ago that a proposed deal to take the company private at $15 a share fell through, following a worse-than-expected quarter. The company remains real estate-rich, owning 232 of its 750 locations and trades at a price-to-book ratio of just 1.1.PBY data by YCharts
Let's hope that today is a bit calmer than yesterday.
