<dd>Subject:</b> [CANSLIM] Alpha vs. RS<br>
<br>
<font size=2>
<dd>Never paid much attention to Alpha until recently. Been wondering how it correlates to RS. I just did a screen on DGO looking for stocks with alpha greater than 3 and used no other criteria. Zero stocks showed up. Then I lowered alpha to 2 and got 1 stock. Then I lowered alpha to 1 and got 41 stocks also with no other criteria selected. Then I added a second criteria of RS of 80 to the alpha of 1 and that reduced my list further to 29 stocks. <br>
<br>
<dd>Here's DGO's definition of RS: '</font>Understanding the price data for stocks is the first step in becoming a smart investor. The next step is learning how to compare a particular stock's price performance with all the other stocks in the market. The Relative Price Strength (RS) Rating measures a stock's price movement over the last 12 months and compares it to all other stocks on the NYSE, NASDAQ, and AMEX markets. The results are ranked on a 1-99 scale, 99 being the strongest. For example, XYZ Corp. has a RS Rating of 98. This means that during the past 52 weeks, XYZ's price outperformed 98% of all other stocks. Stocks rated above 80 in RS Rating can be considered strong performers, and stocks below 70 in RS Rating can generally be considered laggard performers. The Relative Price Strength Rating lets you compare any stock's price performance against the rest of the over 10,000 stocks tracked in the William O'Neil + Co. Incorporated database.'<br>
<br>
<dd>Here's DGO's definition of alpha: 'An expression of how much a stock would have appreciated or depreciated on average every month over the last 12 months, assuming the S&P 500 remained unchanged during the period. For example, an ALPHA of 1.0 means the stock's price would have appreciated at the rate of 1% per month over the last year, assuming an unchanged S&P 500 Index. At least 260 days of price history are needed to compute the Alpha data item. It is calculated at the end of every trading week.' <br>
<br>
<dd>Am I wrong in assuming that a high RS stock should have a high alpha. Do they only correlate during a bull market. Now that I think about it I think Yes. I wonder if I had done the above screen 3 years ago how many stocks would have had alpha greater than 2. Is there any methodology that tracks alpha for the stock universe and flags that conditions are optimum if, say, the average alpha is greater than 1? Just wondering. Or maybe I'm just being obtuse. <br>
