Chasing Value: S&P 500 adds Intuitive Surgical

Last night Intuitive Surgical (NASDAQ: ISRG )reached a historic milestone in its meteoric company life when Standard & Poors decided to add it to the S&P 500 index. It will be replacing Bear Stearns (NYSE: BSC) after J.P. Morgan Chase (NYSE: JPM) completes it's acquisition in the next couple of months.

After a tough day yesterday Chasing Value: Intuitive Surgical confounds Wall Street and closed down to a recent low of $274.75. It opened up today on the news and is currently trading up about 4% to $285 per share, in a market that is trading down across the board.

The following five-year chart illustrates the rapid rise of this highly specialized company that produces a robotic surgical device called the "da Vinci System". They own all the patents for the hardware, software, replacement parts, and service contracts too. That is one big moat around this company.

If you were following my post last year you might have read Serious Money: You asked about Intuitive Surgical? when ISRG was trading in the low $120's. Since that time it has reached $359.59 -- not a bad return. I have been following ISRG since the beginning and own shares at $7.70 the lowest entry point possible post IPO.

The irony of this story is that I also recommended Bear Stearns last year so my best stock pick ever is replacing one of my worst. Intuitive Surgical belongs on your watch list, and if it dips again during the sumer doldrums perhaps there might be another buying opportunity.

UPDATE: ISRG finished the day at $284.77 up $10.02 (+3.65%)
