Volatility in the markets has spiked recently. And while it may be subsiding, some tea-leaf readers expect to see it spike again. 

After all, there is a measure of uncertainty in the markets, and there is much to be uncertain about regarding a whole lot of things right now, like emerging markets, declining oil prices, declining growth in China, problems in Russia … and so on. 

But there’s a seasonal aspect to this volatility, too, which means market strategists are trying to divine whether we can expect more of it, and whether it’s a sign of an imminent correction.
