发帖数: 2000 | 1 Can I say the probability of a random guess that price of a stock
will rise or fall tomorrow is 0.5, given in the long run stock price
almost always go up? | a****g
发帖数: 8131 | 2 you know some people can read charts to gain some probabilities favoring his
bets, in that case, it is not a 50/50
and in a long run, markets are generally going up, which means the
probability of rising is higher than falling
however, this time period should be long enough to digest the noise of bear
markets
