Citigroup Inc. (NYSE: C), Office Depot Inc. (NYSE: ODP) and Gap Inc. (NYSE: GPS) were three of the top stock ideas mentioned from long-time value investor Bob Olstein in this weekend's Barron's Magazine.

Olstein, who is portfolio manager of Olstein All Cap Fund, likes Citigroup for its 4.8% yield and good earnings power when adjusted for the big hit it is going to take from private equity deals it has committed the financing for. The huge international financial services firm should be able to earn $4.50 per share when all the trouble is past, ergo selling for just 10x earnings. Citigroup is also popping up on Eddie Lambert's holdings these days.

Office Depot is another name the value investor likes. After having a great run earlier this decade, increasing from around $12 per share to $43 by early 2006, the stock has since crashed hitting $24. Olstein believes the office-supply retailer can earn $2.50 per share, implying about a 10x price-to-earnings ratio. Office Depot has recently hired management that drove the success at Autozone and the retailer already generates a ton of free cash flow. Olstein has a $35 price target.

One point comes clearly across from Olstein: he is finding some good bargains following the recent stock market correction.
