Buying only stocks announcing splits, Neil Macneale has developed a leading long-term track record. His latest buy in his 2-for-1 newsletter is biotechnology research products firm Invitrogen (NASDAQ: IVGN).

"Wow, investing today is like riding a ping-pong ball; last month I was feeling quite glum about the market and cautioned that we were in for an extended period of below normal portfolio growth.

"That may still be true, but now, as we go to press, the portfolio is at its all-time high and there is reason to believe most stocks we have picked are going to do much better than the overall market.

"Meanwhile, with splits so few and far between these days, one thing is certain; companies that do announce splits deserve a very close look. Our latest selection is Invitrogen. Its primary business is assembling and selling kits used in biotech research.

"I view this as selling the shovels and tents to the gold miners. During the California gold rush, it was the storekeepers that got rich while most of the miners went broke.

"IVGN is not ideal in that it pays no dividend and carries a moderate amount of debt. However, this is a strong business with a history of good earnings and good growth. The healthcare sector has been on the outs for a while now and it's probably a good time to get a biotech company into the portfolio."
