October has historically been the most profitable month considering median (not average) percentage performance, the best in terms of average performance is November.
The problem is almost everyone expects the price to follow that trend, but the market likes to move in the opposite direction to what the majority predicts. We somehow broke the trend and September (historically a losing month) finished with a positive growth, so there's nothing stopping October to also break the trend but in the opposite direction. And when things don't look good around the middle of the month, a panic might kick in and some investors might be heading for the exit.
All in all, I'm staying positive and think there are more signs indicating we might start an upward trajectory soon.
