For questions about this article or underlying research, email [email protected].

Parker Hannifin (PH) operates two businesses, Diversified Industrial and Aerospace Systems, and its stock has beaten the S&P 500 in each of the last five years. While a record like that looks like proof of an exceptional company, hundreds of other large companies had the same five years to beat the same index. Out of nearly 490 large U.S. stocks, how many do you think did the same?

How Rare Is Parker Hannifin's Winning Streak?

Parker Hannifin's share price outperformed the S&P 500 in each of the five years to November 10, 2026. All price changes shown here exclude dividends.

Only 7 of the 486 stocks measured, today's S&P 500 members with five years of prices, beat the index in all five years. Parker Hannifin is one of the seven. One good year is common enough: in the latest twelve months, 53.3% of them beat the index. Five in a row is rare.

Could A Streak Like This Be Luck?

With this many stocks, a few will have long streaks even if no company is any better than another. In a typical year of the five, about 43% of these stocks beat the index. Now suppose it were pure luck which ones. Each year you put all 486 names in a hat and pull out that same share of them as that year's winners.

Do that five years in a row and about seven names come out every single time. On average, seven companies would have a five-year winning streak with no skill involved at all. In fact seven companies have such a streak, about as many as luck alone would give. That does not make all seven lucky, and some may be there on merit, but you cannot tell which from the share price.

Did Parker Hannifin's Profit Grow Through The Streak?

Parker Hannifin makes most of its sales in Diversified Industrial, with Aerospace Systems bringing in about a third. Its twelve-month profit, defined as net income including one-time items, rose in four of the five years of the streak. Over the entire stretch, profit rose 98.4%, while the stock climbed 219.7%.

The exception was the first year, from November 2021 to November 2022, when profit fell 33.3% and the stock still beat the index. Profit growth also slowed to 2.3% in the latest year. So the streak had rising profit behind it in most years, though the share price climbed faster than profit did. Profit, unlike a share price, measures the business itself.

What To Watch Instead Of The Streak

Sales are growing faster now. In the September 2026 quarter, sales from existing businesses rose 11.5%, a figure management said on the November 5, 2026 call was the first double-digit organic growth in over three years. Management also raised its fiscal 2027 forecast for that growth to 9% at the midpoint, from 7%.

A share price streak is a record of the past, whereas profit measures how the business is doing now. Parker Hannifin's net income growth from a year earlier, 9% in the quarter to September 2026, is the figure to watch when the company reports in January 2027.
