Market complacency has re-emerged, warns Deutsche Bank's David Bianco.
His preferred measure of this is the PE / VIX ratio. (PE is short for price-earnings, a measure of stock market value. The VIX is the CBOE volatility index, a rough measure of "fear" in the stock market.)
From Bianco's note: "Our PE/VIX market emotion indicator climbed to 1.3 on S&P trailing PE of 18 and 3m avg VIX of 14. A level between 1.2-1.5 signals complacency. There was similar complacency going into summer last year, with S&P trailing PE at 17.5 and a calm market kept VIX at 10-14. The complacency persisted to July but then faded as the risk of higher yields came on falling unemployment, but yields ultimately stayed subdued preventing any major summer sell-off. Yet a selloff began in late Sept as oil prices started cracking and the dollar climbing."
Bianco illustrated this in a pair of charts, the bottom one decomposing the PE/VIX to its various components.
As you can see, this measure signaled similar warnings ahead of the dotcom bubble bursting the global financial crisis coming to a head.

Bianco is cautious on stocks right now, and he's telling clients the next 5% move in the market will probably be down "given the S&P now at an even higher PE than a year ago, heightened uncertainty in 10yr yields, weak earnings growth and continued soft economic data."
"Historically 5%+ dips are common and happen at least once a year since 1960, except 1964, 1993 & 1995," he noted. "It has been 916 trading days (3.6 years) since a 10% correction. Selloff triggers could be a further rise in 10yr yields especially if UE keeps falling amidst slow economic growth and Fed remains unclear on first hike timing, or a jump in the dollar upon the Fed expressing firm intentions to hike in Sept."
