New Studies in Relative Price Strength Charles D. Kirkpatrick II, CMT www.charleskirkpatrick.com kirkco@capecod.net
What I’m Going to Cover • Look at old studies from book “Beat the Market” • Assess how the triggers developed then have behaved since • Review market direction methods • Show new market direction methods • Show new factors • Adjust old and new factors for new data base
Old Tests • Period 1998 – 2006 • 8,073 stocks weekly • 290,594 weekly observations • Projected relative strength percentile out 3, 6, and 12 months into the future to measure performance of stock’s weekly relative price and price-to-sales percentile. • Summarized results. • Decided on optimal buy and sell triggers.
Old Studies Best Screen from book: “Beat the Market” • Best list from all stocks that have a market cap > $1billion. • Price above ten, and relative price strength only calculated on stocks that have traded about $5 for 26 weeks. • Relative price strength percentile > 97 for buy, < 52 for sell (price screen). • Relative price-to-sales ratio < 42 to buy, > 67 to sell (value screen).
Old Tests for Relative P2S 3-month results
Old Tests for Relative P2S 6-month results
Old Tests for Relative P2S 12-month results
Old Tests for Relative P2S Rising market
Old Tests for Relative P2S Declining market
Old Tests for Relative P2S Results: • Relative price to sales was a viable selection criteria with statistically useful results. • Stocks with relative P2S percentiles greater than 42 and less than 17 were the best picks. • Stocks with relative P2S percentiles greater than 67 should be deleted from any portfolio.

Selection and Deletion Criteria • Selection: (all necessary) • Relative price strength percentile >= 97 • Relative P2S percentile <= 42 or >= 17 • Market cap >= $1 billion and Price >= $10 • Deletion: (only one necessary) • Relative price strength percentile <= 52 • Relative P2S percentile >= 67 or <= 7
Bargain List 2001-2008 Results (period 3/31/2001 – 10/25/2008 Russell 3000, price $5, mkt cap $1000 mil, RS buy-97, sell-52, P2S buy-42, sell-67 • Total Return 9.13% • Russell 3000 Return -19.78% • Annualized Return 1.16% • Annual Turnover 192.86% • Max Drawdown -48.03%
Market Risk • Can use moving average crossovers • Sliding in and out • 25% on cross of 13-week sma • 25% on cross of 26-week sma • 50% on cross of 52-week sma • Golden cross • 100% on 50-day crossing the 200-day sma
Problems • List performance (equity curve) – flat • Number of stocks fluctuates with signals • Too few stocks and too high initial price (done to limit number of stocks in list to a small number) • Price limit for RS calculation too high (s/b < $5) • Many stocks not deleted soon enough • Comparison to market not equivalent (apples to apples) • Drawdown still large • Market risk not sensitive (sluggish to turn)
Solution Market Risk • Use Russell 3000 as the universe and performance comparison. • Run random selection of Russell 3000 stocks and test market risk avoidance methods. (Result should be method that can be used in any portfolio selection model). • Make criteria sensitive to market turns.
Solution Stock Selection and Deletion • Lower minimum price to $2 • Lower minimum market cap to $100 million • Lower back testing price to $0.01 • Adjust RS selection and deletion triggers • Adjust P2S selection and deletion triggers • Add a percentage stop to cover periods between weeks
