Simulations by Sector



We have run back-test simulations for over 2000 tickers in various sectors from 2000 to 2008, and most of the results are linked here for representative purposes.  Please call or write for a current dataset.  Access database files collect results from various simulations that can be read into other systems more easily.  Comma separated text files are also available.  If importing into your own systems from the Simulation Result table, your interest would lie in the Ticker, Monthly, Market Price On, and Model Price columns for monthly rebalancing, and Earnings Release Date and Release Date Price columns if you choose to update positions intra month during earnings season.  A number of additional columns are available for convenience and testing, including Market Price, Long Short which signifies if our simulation was long the stock (1) or short (-1) for that month,  Market to Model ratio which determines whether the stock is cheap (if under 1) or expensive and to what extent, Exit, which signifies that the simulation exited the position that month, which can occur at month end or earnings release either by approaching model value or hitting the stop loss. 

All simulations are run in 4 year batches, long/short, -10 to +30% net exposure which varies as an aggregate of long and short positions, but is typically positive and close to the upper bound.  The rebalancing is monthly, individual stocks can trade at the close after earnings release (with additional 2.5% slippage in that event.) Transaction costs are 12.5c roundtrip including commissions and slippage. The point of entry is when a stock is about 25% cheap (long) or expensive (short), exit is at 10%.  This is determined by the ‘Market to Model’, or MM ratio.  Please see further notes below.

N.B. Dividends,  interest and short rebate are ignored, although a portfolio built on the methodology tends to be net positive on all three. Stocks are traded until an ‘event’ takes place i.e. merger / acquisition / bankruptcy etc., at which point the simulation stops allocating capital to the ticker. This is also somewhat naďve, in that certain events should not exclude the stock from further trading, but ensures no survivor bias.

In the absence of availability of an earnings release date history the lag between end of quarter and filing is assumed to be 30 days. This is conservative because actual earnings are released anywhere from a week to 45 days (SEC limit) after the end of the quarter. If the assumed Filing Date for 8k falls on a weekend, the Market Price for trade execution is the Market Price On date of the next Monday. If the rebalancing Market Price On date is on the weekend, the prior Friday’s close is assumed to be rebalancing.

The entry/exit valuation band should really be adjusted for mega caps e.g. the most effective band for just Dow stocks is 15% and 0%, but we have not done that yet. The ‘net’ returns towards the bottom of the summary page of the spreadsheets are after an assumed fee of 1.5/20%.
