Millennials tend to get a bad reputation from older generations as entitled, self-centered, and periodically lazy. Not all millennials fit those categorizations, however. In fact, 3.2% of the ultra-wealthy global population falls within the millennial age range – not bad considering their relatively young age and the time it takes to accumulate such great wealth. These 30 millennials did not inherit a business from his or her family – they are all self-made entrepreneurs.

Mark Zuckerberg is the quintessential example of a now wealthy millennial who hit the ground running from an early age and ended up scoring big. Creating Facebook in the comfort of his dorm room at the age of 19, Zuckerberg is now worth some $74 billion — he is not only the richest millennial, but also the fifth richest person in the world. Several other booming businesses such as Airbnb, Instagram, and Snap Inc. were created by millennials who are now world-renowned billionaires.

To identify the richest millennial entrepreneurs in the world, 24/7 Wall St. reviewed a slew of credible sources, most notably Forbes, Bloomberg, and Wealth-X, to find people with the greatest to-date net worth. We used Pew Research Center’s definition of a millennial — those born between 1981 and 1997. Those above the age of 36 years old were not considered.

401(k) investors should break out their rally caps and root for stocks to keep going up in January.

The reason: How equities fare in the first month of the year often signals how they will perform for the full year.

And, so far in 2018, stocks are in rally mode.

They have closed higher the first four trading days, raising the hopes of 401(k) investors for more gains ahead, following a 25% return for the Dow Jones industrial average in 2017.

The gains have been powered by optimism that the economy and corporate earnings will benefit this year from tax cuts engineered by Republicans. Those positives are offsetting challenges, like a pricey market, an expected rise in interest rates and signs that investors are getting too optimistic about the market’s prospects.

Getting off to a good start on Wall Street is often the difference between full-year success and failure, according to The Stock Trader’s Almanac.

In fact, 401(k) investors’ odds of making money in stocks again in 2018 will rise dramatically if the market can notch what the Almanac calls a performance “trifecta” this month.

We’re not talking about a horse-racing trifecta, where bettors win when they correctly pick the order of the first three finishers in a race. A Wall Street trifecta is when the stock market does three things: It posts gains in the seven-day “Santa Claus Rally” that straddles December and January; it rises in the first five trading days of a new year; and it ends January with gains.

Of the 29 times since 1950 in which the S&P 500 stock index rose in all three of those periods, it finished the year higher 27 times, or 93% of the time, according to The Stock Trader’s Almanac. Following those trifectas, the large-company stock index posted average full-year gains of 18%.

Those statistics back up the saying coined by the Almanac, “As January goes, so goes the year.”

So far this year, odds favor another good year for stock investors. The S&P 500 was up 1.1% during the Santa rally, which ran from Dec. 22 to Jan. 3. And it has risen the first four days of January, gaining 2.6%. If stocks stay in the black through January 31, it would be a bullish signal.

“A positive first five days and January would certainly boost prospects for full-year 2018,” noted Jeffrey Hirsch, the Almanac’s editor.

The first five days of the year is dubbed an “early warning system,” while the full-month market watch is known as the “January Barometer.”

There are a few reasons why a strong January often leads to further gains, says Sung Won Sohn, professor of economics at California State University Channel Islands.

Stock price trends and investor psychology are big factors.

“Once the bullish sentiment builds, it does not dissipate right away,” Sohn tells USA TODAY.

Still, Sohn warns that too much of a good thing might eventually be a negative.

“The market always overreacts in both directions, creating booms and busts,” Sohn says, adding that investor enthusiasm is getting overdone. “We are in the ninth inning of the (rally). I would be cautious and raising cash.”

There are two key reasons why stocks tend to rise early in a new year, says David Kotok, chief investment officer at Cumberland Advisors, a Sarasota, Florida-based investment firm.

Investors that were selling stocks late in the prior year for tax purposes finish that process, he explains. In addition, fresh cash becomes available for investment as the calendar turns.

Kotok expects the early-year stock strength “to continue for awhile.”

He sees stocks being bolstered for the rest of 2018 by tax cuts.

“Short-term, I’m bullish,” he says.

Funny thing about our federal system of government: There’s that complicated tax code that Uncle Sam keeps and the IRS enforces.

Then there’s an even larger patchwork of taxation schemes crafted by 50 state legislatures, all coming up with new ways to extract coin from their citizenry (or create social policy through tax breaks). Some of these regimens are, well, quirky.

We’ve found ten of the strangest ways states tax you and cut you a break—plus a few creative tax dodges—from across the land.
