I realized as I was backtesting some of my two-way (long short) strategies that my results may be somewhat skewed because delisted stock data was not included.

For instance, how can you determine the overall success of backtest during the 2008 downturn without Bear Stern and Lehman short trades included...

Any thoughts?

+1 on this. Is there an official word on delisted stocks?

+1

or maybe more importantly long trades on bear stearns and lehman.

I wouldn't hold my breath waiting for this, though.....
