Whoever believes the fear driving prices higher is even stronger than the fear that drives prices lower ... is smoking something.
Stocks/bonds/options/index futures/forex/Pet Rocks, don't matter.
Majority are buyers: Mutual funds, the public, long term investors. Hedge funds and traders (defined as those of us who actually trade both directions - gee what a concept) are the minority. Not in pure dollar amounts maybe. I don't know the breakdown nor do I care. The majority panic often when a top sets in. While the inverse a bottom often takes forever to get out of its own way.
Though I do agree commodities (softs, energy and metals) can often move up or down equally fast.
