NEW YORK (CBSNewYork) — Seconds after trading began on the New York Stock Exchange Wednesday, the Dow Jones Industrial Average crossed the 22,000 benchmark for the first time ever.

As CBS2’s Alice Gainer reported, hats were even made to celebrate the 30-stock index breaking above that level.

But what does 22,000 really mean?

“Ultimately, it’s just a number,” Robert Fuest, CEO of Fuest & Klein Wealth Advisors said. “Some assets are going higher and it’s dragging the entire Dow, Nasdaq, and S&P up. It’s very heavily weighted in specific names.

One of those names is Apple, which boosted the Dow as its stock soared on the news that earnings beat Wall Street expectations. The company reported stronger than expected iPhone sales.

There’s also the anticipation of their 10th anniversary iPhone, coming out this fall.

So what does the Dow surge mean for you and your portfolio?

Fuest says says it’s best to stay the course.

“In their retirement accounts if they’re under the age of 55, they’ve got plenty of time, so continue to purchase and purchase, max out your 401(k),” he said.

Experts also suggest you invest in mutual funds versus specific companies.

At the closing bell Wednesday, the index sat at 22,016 — a gain of 52 points and its sixth record-high in a row.
