Well, I say let the stock market tank. It'll adjust itself to a realistic level at some point.
Stockbrokers and day traders are the wussiest bunch of people on the face of the planet. Take these headlines:
"Stocks fall on oil supply fears"
"Stocks fall on interest rate fears"
"Stocks fall on fears there's something hiding under my bed"
Here's how to put a stop to the volatility.
First, stop the practice of "short selling" altogether. Nobody cares if you have your Tupperware or Avon orders drop-shipped to the purchaser, but if you're selling something like a commodity or a stock, you should at least OWN it and not just be BORROWING it. I believe in the real (not stock market) world, selling something that's being used as collateral for a loan is called "disposing of property ;under lien." It's illegal in real life. If Enron had been required to actually OWN what it was SELLING, it wouldn't have tanked - nor would it have grown into a behemoth that took so many people down with it.
Second, new rule: If you buy a stock, you have to keep it for at least 60 days before you can sell it to somebody else. Doesn't matter how much whining Baby Bob and Jocko the Clown are doing while trading stock on E-Trade and deciding what to do with their extra coins. (Rumor has it that Jocko's been laid off, by the way, and Baby Bob was spotted on the corner selling apples to tourists earlier this week.)
Third, make it illegal to go public with a stock representing a company that is nothing more than the ILLUSION of profitability. Back during Clinton's term and at the start of George Bush's term, companies were going public and suddenly having billions of dollars in market capitalization even though they had never shown an actual profit. You buy into that kind of illusion, you deserve everything you get ... or lose ... or whatever.
Fourth, diversify. If you have a good money manager, and the stock market starts plummeting, he'll put more of your investment in the futures market. If that's falling, he'll put it in gold. If that's tanking, he'll take $400,000 of it for a trip to a spa resort and put the rest of it in a mayonnaise jar under his bed. Relax. If it doesn't work, you can be one of penpals while he serves a nice term in a cushy Federal prison - unless you can get to him with a Louisville Slugger before Federal marshalls find him.
That's a good start. I'm sure I'll think of others.
