Hi Leslie,
I appreciate your email.
After the bug was fixed in the data I created a blog post regarding the update, and updated the documentation on the model. I should have sent a global email.
I will provide the details but for reference I am posting links to the blog post and the updated reference.
Blog Post: Stock Market Timing Model - Update
Reference Section: Market Timing Model - Read Section II and III
Taking Long or Short Positions
1. Buy or Short: The Reference Section discusses using a MidCap 400 ETF for a simple ETF strategy. A MidCap 400 ETF more closely mimics the Value Line Index. The only other alternative to match the performance would be to buy Futures Contracts or Options on the Value Line index at Kansas City Board of Trade.
2. When To Buy Or Short: All the calculations for the model (posted in the reference section) were done at the next day opening price.
Lets say the model gave a market up call. Buy next day at the opening BUT always use a limit order. Trading market orders is dangerous, plus most brokers charge the same for market or limit orders. I use Interactive Brokers and pay $1.00 per trade. Also I ran tests for buying the next day only if the price trades above the high (for LONG) of the prior day. This would indicate that the market is moving in the direction of the signal. This results were not good so next day at the open with a limit order is the way to go.
Overall the MTR-TM as the 4% Model is supposed to be used to time the overall market. It can be used in this manner (to buy stocks), but just as we have seen this past week the DOW, S&P 500, and NASDAQ do not all perform the same over the short term so for an ETF strategy a MidCap 400 ETF must be used.
I want to make one final note about market timing. Leslie Masonson, the author of "All About Market Timing" reviewed many marketing strategies in his book. The 4% Model, a 4% Daily Model, a 6% NASDAQ model and others. One very important piece of advice he gave was this "No matter what system you use trade each signal." He said this because, as we have seen with the MTR-TM sometimes a signal maybe very short in duration, some longer. So when the signal fires, trade, and use stops.
Leslie please let me know if more clarification is required.
Thank you,
Patrick
