Volatility is back. The CBOE Volatility Index, the market's so-called fear gauge, stretched over a 22 percent range in each of the past two weeks, its first such streak since March.

Though AAPL popped in the middle of the conference today with some flashy news, that's not necessarily cause for long-term optimism. Shares of Apple are down nearly 24 percent since last year's WWDC and off 38 percent from their record high of $700 in September.
In fact, going back five years, AAPL's average return during the five-day WWDC is negative 3.92 percent.
Furthermore, the WWDC typically takes place in June, and AAPL's average performance is negative for the month. Although the stock's devastating 11.30 percent decline in June 2008 skew the average to the negative territory, the stock is again down roughly 2.5 percent in June this year.
On an upbeat note, the stock bounced off its lows in April this year and is up roughly 17 percent since then. It also reclaimed its position recently as the world's most valuable company after briefly losing it to Exxon Mobil earlier this year.
Here's a look at APPL's returns during the WWDC for the last five years:
Year to date, both assets have moved in tandem and by similar magnitude, each gaining over 14 percent in the same period.
However, with the downside momentum gaining, will the greenback drag down the Dow further?
Tuesdays have been exceptionally good for the Dow Jones Industrial Average and if the index finishes higher today, it will mark the 20th consecutive positive Tuesday close.
The current streak is the longest Tuesday in history and the second longest ever for any day of the week. The last time Dow Jones even got this far was in 1927 when it closed up for 15 consecutive Tuesdays from June 1927 through September 1927.
In 1968, the the Dow rose for 24 straight Wednesdays from June through November.
So far this year, Tuesday has also been the best day of the week for Dow Jones, with an average gain of roughly 0.50 percent. And the second best? Friday, with a gain of 0.33 percent.
On the other hand, Monday has been the only negative day, with the Dow falling an average of 0.23 percent in 7 of the last 10 instances.
While the Dow already broke the most number of consecutive positive Tuesdays, if Nasdaq closes positive today, it will tie with 10 consecutive Tuesday close that occurred between September 1972 through December 1972.
The Dow Jones Industrial Average set an all-time high Thursday and is now up nearly 22 percent since mid-November.
The market has not closed down for more than two straight days this year, while the percentage of stocks hitting new 52-week highs Wednesday surged to the highest level in nearly 25 years.
Those numbers have led many investors to believe the market is overdue for a pullback.
According to Wall Street research firm Stratega, however, a long-trend market can persist for years. The firm notes that there were no 10 percent corrections between 1962 and 1966, 1984 and 1987, and 1990 and 1997.
Other clues may be found in the strong correlation between this market and the one in 1958.
CNBC's Analytics team went back to 1900 to find other times when the Dow traded in a similar pattern. The market performance in the last 100 days closely resembles the period between July and November 1958, with a correlation match of 97 percent.
Back then, the market took a brief pause, pulling back about 5 percent before rallying 14 percent through the first quarter of 1959.
Here's a chart displaying the correlation between the current bull market and the one in 1958.
Despite gold prices bouncing off their April lows, investors continue to pull money out of the precious metal and plow it into equities, as the stock market keeps climbing to new highs.
Since bottoming at $1,321.50 on April 16, gold prices have stabilized and rallied more than 11 percent, but the SPDR Gold Trust ETF has had more than $4.4 billion in outflows, according to IndexUniverse.com.
The exodus from the biggest commodity ETF is nothing new. Last month, the GLD experienced $6.8 billion in outflows, putting the total figure so far this year at $14 billion.
As fund flows decrease, the GLD is no longer the sixth-largest holder of gold in the world. For the first time since the second quarter of 2008, the ETF's bullion levels fell below China's gold reserves.
The Dow is up 20 percent since the most recent low on Nov. 15, but 12 stocks that have been kicked out of the index over the years have risen an average of 30 percent. These are all stocks of companies (or their descendants) that are former Dow components, comprising the ones that still trade in some form.
As a comparison, CNBC looked at the performance of the 10 new Dow members since November 1999, when Intel and Microsoft became the first tech and non-NYSE traded stocks to be included. Those 10 stocks had an average gain of 24 percent between the November low and now, better than the overall gain for the index but still shy of the 30 percent increase chalked up by the ousted stocks.

Here is a look at the performance of the stocks in the "rejects" club since mid-November.
In a relentless rally, the S&P 500 is up 19.3 percent since mid-November, breaching 1,600 for the first time ever on Friday and settling at a record close of 1,614.42.
Since the low last November, five S&P sectors are already in bull market territory: financials, health care, consumer discretionary, utilities and consumer staples are all up more than 20 percent.
More than 86 percent of the S&P 500 stocks are trading above their 50-day moving average. Some of those companies, however, have significantly broken out from their trading range.
Price momentum is a relatively short-term occurrence, and as it starts to wane, the stocks that have deviated too far from their respective averages tend to revert back to their means.
Case in point: First Solar. Although FSLR lost almost 9 percent on Monday's trading session after missing first quarter estimates, the stock has moved more than 31 percent away from its 50-day moving average.
Similarly, Gamestop is trading more than 27 percent away from its 50-day moving average. Gamestop and First Solar are among the most shorted stocks in the S&P index, with more than 30 percent of their float sold short.
The S&P 500, which has also gained significant upside momentum since the beginning of the year, is up more than 4 percent from its 50-day moving average for the first time since mid-February.
Here are some additional names trading at "overbought" levels.
After a temporary drop in the second half of March, short interest is back on the rise.
The NYSE recently reported that in the first half of April short interest rose to 13.36 billion shares from 13.23 billion on March 28, a one percent increase.
Likewise, NASDAQ also showed an increase of 1.4 percent in short interest during the same period.
According to data from FactSet, more than 58 percent of S&P 500 companies saw a spike in short interest in the first two weeks of April.
Short interest measures the total number of shares of a security that has been sold short, expressed as a percent of total tradable shares.
Investors track short-interest levels to gain a sense of where a stock might be headed, along with some insight into whether any positive news might force short traders to cover their positions, pushing stocks higher.
J.C. Penney, Gamestop and First Solar, for example, have some of the highest ratios in the S&P 500 index, with more than 30 percent of their float sold short.
