The public's become bored with "Playing Stocks." I have no idea why; but those things happen. Perhaps it's related to the recent broad decline in gambling... casinos, lotteries, horse racing (which is nearly dead). There's a fad element to "flipping" stocks (although making real profits NEVER goes out of style LOL!).
IMO the reason for all of these is people have moved on. Most people go with whatever is the fad of the day. Doesn't matter if it is stocks, golf, Nascar, motorcycles, or guns. Of course losing their money always plays a role.
