According to the company's most recent proxy statement, Stewart owns about 30 million shares, or about 61 percent of the total number of shares outstanding. The company's stock has soared in advance of Stewart's release, closing yesterday at $33.95, up $1.91, after falling as low as $5.26 on Oct. 9, 2002, when Stewart's ImClone stock sale scandal was in full flower.
But some Wall Street analysts and professional investors view the shares as overhyped and overpriced. Some say the stock has been boosted by a "short squeeze" in which investors who bet that the stock they had borrowed would fall have been forced to buy shares to limit their losses.

Video: Wasting no time, Martha Stewart left prison early Friday and quickly set her sights on rebuilding her homemaking empire after serving a five-month sentence for lying about a stock sale.

On the positive side, anecdotal reports suggest advertisers are warming up to the company's flagship magazine, Martha Stewart Living. But it will be at least a couple of months before it becomes clear whether the title can fatten up to its pre-stock-scandal size. That won't be easy, as magazine racks now teem with good-living guides such as Real Simple and O, the Oprah Magazine.
And, in addition to her "Apprentice," Stewart will host a daily lifestyle show that will air on most NBC affiliates. Stewart supporters cite high demand for the show as an indication that the public will warmly embrace a post-prison Martha. Unlike the "Apprentice" spinoff, which will be unaffiliated with the company, Martha Stewart Living Omnimedia will receive much of the advertising revenue from the daily syndicated show, which is to begin airing in September.
That would also boost a sagging part of the company's balance sheet. With Stewart in prison and off the air, television revenue in the fourth quarter dropped to $1.1 million from $5.9 million a year earlier.
Among bright spots cited by Lyne and others, the company launched the "Everyday Food" television show on PBS in January, building on the success of Everyday Food magazine, which Lyne said was growing quickly.
Lyne also said she would focus on packaging the company's "evergreen" media products, such as how-to cooking and entertaining videos for delivery over multiple media devices.
And Lyne said Stewart's "Apprentice" show would draw more people to the brand and bear little resemblance to the current version, with Donald Trump's signature boardroom firings.
"Within the basic format I think there is a lot of leeway for her to create a show that is comfortable for her tonally and features tasks that are more in keeping with the creative work of a company like ours," Lyne said.
If Stewart were allowed to become chief executive again, some corporate consultants say it would be a bad idea, especially with an executive as talented as Lyne already in the slot and because it might derail the company's efforts to make itself about more than just Martha.
Instead, consultants say, Stewart should give up control of day-to-day operations and allow the company to chart its post-Martha future.
