Procter & Gamble stock is near all-time highs as its turnaround efforts appear to be taking hold.

Shares peaked just 30 cents below $100 last week, which begs a welcome question that investors haven't been able to ask in 15 years: When will P&G stock split next?

Usually, when P&G stock crosses the century mark, the consumer products giant doubles the number of shares outstanding with two-for-one splits. Since 1970, P&G stock has traded for several weeks or a few months north of $100 before shares split.

The longest time the shares traded above $100 was for about a year in the late 1990s when the stock traded above $150.

With 10,000 P&G employees in the region and legions more retirees, P&G is one of the most widely held stocks in Greater Cincinnati and Northern Kentucky.

P&G officials generally don't comment about the company's stock price and didn't offer one when asked about splits by The Enquirer last week.

Still, the last time, P&G's stock closed above $100 for just over one month in early 2004, the company announced a two-for-one split.

While the swiftness of the split announcement suggests there might have been some automatic benchmark, it might have been the result of a previous split plan that had been put on hold.

P&G's stock also closed above $100 several times in late 1999 and early 2000, but a split wasn't declared and the stock market saw a major downturn in March 2000 when the dot.com bubble burst. Also wreaking havoc that spring: the implosion of CEO Durk Jager's short tenure.
