""Biggest problem I find with shorts is that they tend to have more tenacity and stick-with-it than longs. Short don't bail out as much as longs do when stock goes against them." - Long Ways"
You stated that your wife bt & kept stock for a year and made 80% profit. Congratulations to her (and you) on both counts. Unfortunately, majority of long investors get shaken out when investment goes against them. Shorts tend to stay the course - as we see here with wgo now challenging 30 instead of 50.
