Price to Free Cash Flow was >60 times! But now there is NO FREE CASH FLOW! Throw in heavy insider selling and watch out for "air pockets" because I don't think this valuation is sustainable. Long term holders will wait until next year to bank capital gains, so make sure you are short at the end of the year. January should be a big one on the downside, if the historical pattern plays out. Sell call spreads and buy puts with the credit to manage risk, because the 'greater fool theory' is still the way the market works. In other words, the market can still go up despite being in "fools only territory".
