he Internet is hot, and CMG Information Services of Andover, which has its fingers in 22 Internet-related companies, is quadruple-hot.

Chalking up a 378 percent gain in share value for the 12 months ended March 31, CMG landed squarely at the top of the Globe 100 list of market bulls - for the second time in three years.

That torrid pace by a company best described as an Internet incubator was more than triple the growth posted for the period by two major Internet-based mutual funds - and nine times the growth recorded by a third such specialty fund.

Most of this rapid rise occurred after Microsoft Corp. and Intel Corp. each announced they were buying 4.9 percent stakes in CMG, valued between $10 million and $11 million. Sumitomo Corp. later chimed in with a similar investment.

Other milestones during the year: the purchase by Framingham-based Lycos Inc., a big CMG-backed Internet search-engine company, of Tripod Inc. of Williamstown ; and a new chief executive at another CMG enterprise, GeoCities - seen by some as the final step before GeoCities goes public.

And the beat kept on. Wrapping up the Globe 100 survey period at 57 15/16 as of March 31 , up 45 19/32 since March 31, 1997, CMG shares this month topped 100, and last week hovered in the high 90s. For the 12-month period ending March 31, 1996, the stock was up 508 percent.

Andrew J. Hajducky III, CMG's chief financial officer, laid most of the recent boost to the buzz generated at an investor meeting at which the company explained itself, starting with its management of three venture capital funds that hold positions in 15 Internet-related companies.

That's in addition to seven companies CMG owns outright.

''The CMG story is a complex and complicated story,'' said Hajducky - and a far cry from the company's beginnings, in 1969, as a marketer of educational publishing materials.
