2005 was a good year for my guru strategies. If you had bought all 89 of the stocks I wrote about on the same day I touted them, you would have had an average gain of 7.7% at the end of 2005. This compares with a gain of 3.3% from investing in the

S&P 500

over a comparable period.

Let me explain how I did the math. I took the closing price of each stock on the date I recommended it and compared it to its closing price for the year. Taking all the winners and losers, the average gain per recommendation was 7.7%. Each recommendation was given equal weight.

Then I sought to find out how much investors would have made if instead of buying my picks, they had put the same amount of money in an S&P 500 index fund instead on the date of each recommendation. The average gain from investing in the S&P 500 would have been 3.3%.

Fifty-two of my picks (58%) went up and 37 (42%) went down.

By way of comparison, the

Dow Jones Industrials

dropped 0.61% for the year, the

Nasdaq

rose 1.4% and the S&P 500 gained 3%.

I recommended

Google

(GOOG) - Get Report

in my

April 25 column when it was trading at $223.53. It closed the year at $414.86, gaining 85.6%. During that same period, the S&P 500 gained 7.4%.

In addition to Google, some of my better calls were:

Holly ( HOC): 125%;

Western Digital : 57.6%

; and

Southern Copper ( PCU): 48.4%.

My biggest losers included:

Movie Gallery ( MOVI): -85.6%;

Toll Brothers : -29.4%;

and

CNS : -25.1%

My investment strategy is simple but rigorous: I have distilled the strategies of some of the greatest investors in history into discreet, quantifiable steps (these investors include Warren Buffett, Peter Lynch and Martin Zweig). Using a computer program I created, I screen all publicly traded stocks. Those stocks that receive a strong recommendation from at least one of these strategies are eligible to be written about in my column. Usually, though, I wait until a stock earns a strong thumbs-up from at least two strategies before I write it up. There is no emotion behind these recommendations, no prognostications -- nothing but computer-generated calculations.

Below, I've listed all my recommendations from Jan. 1 to Dec. 30, 2005. All the data are split-adjusted. The returns cited don't include dividends or transaction costs.
