Been reading some studies to build more confidence in my short trading in these sorts of stocks
Heres 2 interesting ones:

The first finds that stocks that are likely to be bankrupt(according to predictive model the authors invented) have really poor stock returns
The second finds that companies that are likely to fail(their definition of failure is delisting due lack of performance in different areas) earn very good stock returns
So what do make of this?the key there is the difference in definition, the first study(along with other studies that are similar that I haven't read) look at really bad companies that are likely going to bankrupt, in this situation it seems that there is an edge. The authors speculate the reasons for it
I agree with a few of them
1 - Prospect theory, the fact the returns are skewed to the positive gives a lottery ticket effect to these stocks, which leads to mispricings due human errors
2 - Little or analyst coverage, institutional ownership, illiquidity and difficulty shorting makes those mispricings not go away easily
The 2nd study since it has a broader definition of failure doesn't capture those effects. Being delisted due performance reasons seems to encapsulate more 'corporate uncertainty', that is business that are going to transformations, tough periods, management suspicion etc. In that case its not surprising that are good returns in the stocks. Its just not horrible enough that people's denial could lead to mispricings and hopes/dreams, in this case its just bad and people tend to sell the stocks to bellow their fair values leading to excess returns for longs
At least this has been my interpretation of the studies
