It was the lack of the uptick rule that left so many financial institutions open to shorting attacks last fall. It worked fine for years with the uptick rule.
Be very clear. The problem is NOT naked shorts. The problem is the spreading of lies by people with short positions. The problem is that the SEC have almost never enforced 33 Act sec17 The problem is that the legislature has eroded the balance of powers of the constitution and prohibited private lawsuits against the people who commit this crime.
