Where will PESI be tomorrow vs. 12/31/13? Tomorrow is the last day to buy shares and still be able to sell any losing lots in 2013 without creating a wash sale.
YTD 2013 about 1.8 million shares traded on days when the low price was above Wednesday's close ($3.40). About 3.0 million shares traded on days when the high price was below $3.40, and 1.0 million shares traded on days when $3.40 was between the day's high and low prices. Prior to 2013, PESI traded at or below the split-adjusted price of $3.40 on only 3 days -- November 21, 2008 and the last two trading days of 2012.
I don't believe the wash sale rule will come into play at all.
Individuals will sell right through the end of December to book their gains/losses and the extremely high majority aren't concerned with wash sale rules thinking they want to repurchase.
I sold on the last runup over $4 and will begin repurchasing soon as we get into mid/late December.
With the current loss and no real reason for near-term enthusiasm, I think there is a higher probability the shares trend lower through year-end rather than higher. It is possible that the shares go back to gatr55's $2.50 post-split price by Jan 1. We'll see.
