objective evidence and fundamentals are not enough for day trading , often the market is in a risk off mood and the only way to make money is to short , this means even rock solid companies go down in price , ive tried trading in and out of stocks in the past and made money for a while but eventually i realised im not smart enough to beat the likes of a long term hold index fund
I think you misunderstood me. I wasn't asking if day traders are using objective evidence, but whether there is objective evidence that the "chartist" approach works for them. That's just a matter of collecting data about people using it and how they fared. It seems to me that any approach that is not in some way "value-based" must be a zero-sum game for all market participants. So then it becomes an arms race to find the best algorithms. Even if you find them, somebody's eventually going to come along with better ones and eat your lunch.
Day trading is gambling, not investing. If you go to the casino and keep putting everything on red or black, someday your luck will run out. Daytrading, gambling on irrational market movements, is the same.
I think that's the wrong analogy. There are two reasons why you might lose all your money by betting on red or black: 1) in a random sequence there will be arbitrarily long runs of any given value (i.e. wins or loses) so unless you have an infinite amount of money, you will be wiped out, 2) the odds are tipped against you because every now and again the result comes up green and everyone loses.
I think the first of these is the one covered by the adage that "the markets can stay irrational for longer than you can stay solvent". The second does not apply to markets -- they go up in the long run, otherwise even people who engaged in buy-and-hold would eventually lose. A roulette analogy would be if everyone
wins when green comes up, so there is a slight edge in staying in the game.
I guess people who do anything other than buy-and-hold are trying to extract more value from the market than just the average increase. Does anybody manage it, and how is it done? Even if we dismiss day traders, there must be people who believe it can be done, otherwise there would be no fund managers and people willing to buy into their funds. (I'm aware of the statistic that most fare no better than market indices).
One hypothesis I'm interested in is whether a less aggressive approach to finding value is possible. Day traders, according to the previous poster, have to short stocks if they can find nothing to go long on. Fund managers have to keep trading -- that, after all, is what they are paid for. I've even read about ones that know the markets are generally over-valued but "it's the only game in town". With one or two notable exceptions, none of them ever say "right, it's time to exit the market for the time being".
I, on the other hand, can take it or leave it. So far I've bought things that look to have dropped for reasons that have nothing to do with value. I wouldn't be an expert on valuing a stock, but I know when something goes down without any apparent associated bad news. I don't fixate on 50 day moving averages etc. If I can't find anything to trade, I'm happy to stay away completely and that's what I've done for 50% or more of the time. I'm in the lucky position of having low income requirements compared to my assets.
I feel more comfortable dipping in and out. If the market is -- as some people claim -- generally overvalued, isn't it the buy-and-hold approach that must suffer in the medium term for new entrants? (For anyone who's read the whole thread, that brings us right back to where the OP began).
