LeapFrog Enterprises (NYSE: LF) reported a decent quarter, but I won't be buying the stock. I just think there are better ideas out there in this sector. First, let's play around with the numbers.

For Q2, LeapFrog saw its top line increase by 22% to a little over $68 million. The net loss was 32 cents per share versus a net loss of 44 cents a year earlier. According to Earnings.com, analysts were expecting the loss to be about 44 cents per share. There was, however, a little help from a tax benefit in the quarter; last year, the company recorded a tax expense. LeapFrog not only scored on the bottom line, but it also expanded its gross margin. So, the quarter seemed all right. But, I then look at the cash flow statement and see that LeapFrog has been using cash for operations the last six months. In the similar time period a year ago, LeapFrog reported positive operational cash flow.

LeapFrog's stock was up over 5% in after-hours trading on Monday after the earnings release. The stock has been strong in a bad market according to the AOL Finance snapshot, and the pop in the after-hours session placed it close to a 52-week high. Again, though, I think there are better ideas out there. Hasbro (NYSE: HAS) is a toy company I'd much rather align my portfolio with. I could even look at Mattel (NYSE: MAT) and JAKKS Pacific (NASDAQ: JAKK).

I know that the stock may be signaling better times ahead, and toy companies certainly make their profits in the latter part of the year, but I still am cautious on this business. When I wrote about the company's fiscal year, I also noted bad cash-flow characteristics, as well losses on the bottom line. So, in the end, I just don't want my portfolio to play around with this low-priced equity.

Disclosure: I don't own any company mentioned; positions can change at any time.

My eldest child spent a lot of her young childhood with a LeapPad on her lap. Introduced in 1999, the LeapPad was an overnight hit that catapulted the maker of the reading device, LeapFrog (NYSE: LF), into stardom with a rocket of a stock to boot.

According to the company, LeapFrog went on to sell 30 million LeapPads and related products worldwide, as well as more than 70 million companion books. In 2003, the LeapPad family of products brought in $330 million, nearly half of LeapFrog's revenue. Since then, the company has suffered at the hands of lower-priced competitors, lack of another blockbuster hit (although the firm has has launched critically-acclaimed products), and video games.

So, today's New York Times article, "LeapFrog Hopes for Next Hit with Interactive Reading Toy", may be what the company needs to help an ailing stock. The Tag certainly looks cool. It is a thick, white-and-green plastic stylus that turns paper books into interactive playthings. Like the LeapPad, kids can tap a word with it and the stylus reads the word, or its definition, aloud. They can tap on an image to hear a character's voice come alive.
