The Dow Jones Industrial Average on Wednesday notched a psychological milestone at 22,000, highlighting a steady record ascent for the blue-chip benchmark.

The 30-component Dow industrials DJIA, +0.51% hit its 32nd record close of the year on Wednesday, powered by a rally in shares of Apple Inc. AAPL, +1.57% , which ended at an all-time high following better-than-expected results late Tuesday

The Dow last hit 21,000 on March 1, but has advanced in fits and starts over the past five months amid growing doubts about how quickly President Donald Trump can implement pro-growth policies pledged during his campaign for the White House. A defeat last week in passing a bill to revamp the Affordable Care Act, known as Obamacare, underlined those fears.

The close above 22,000 represents the seventh fastest such move to a 1,000-point milestone for the Dow at 107 trading sessions (excluding the day it hit 21,000 in March and Good Friday on April 14 when markets were closed), according to WSJ Market Data Group. The blue chip average has now hit three 1,000-point milestones, or moved at least 3,000 points, in a single year. Of course, the higher the DJIA rises, the smaller each 1,000 point move is in percentage terms.

The blue-chip gauge has enjoyed a relatively steady advance, powered by stellar moves in shares of plane maker Boeing Co. BA, +0.28% , which has been a key driver of the price-weighted average over the past six months and notable over the past week. Boeing shares have climbed 53% so far this year, making it the best performer in the benchmark and the fifth best year-to-date performer in the broader-market S&P 500 index SPX, +1.05% .
