Nothing wrong with that. The hard part in investing is admitting your analysis was wrong and redoing it. It's far too easy to cling to a failed theory instead. On the flip side, it is important to cultivate your own theories and not rely on people with axes to grind. I have made plenty of mistakes following people with an emotional like or dislike for this or that. The best advice will come from someone who is completely unemotional about the situation.
“It’s far too easy to cling to a failed theory instead.”
That’s the crux of the matter I think. Emotions can be fatal in trading. Personally, I get into “analysis paralysis”. Stops are critical for me so that the emotion is removed from the trade and I take the loss before it becomes catastrophic.
