Parece que todo mundo é devoto de DCA hoje em dia

It's a valid point. DCA works best for steady, upward-trending assets. For something showing persistent weakness, it's fair to question if the underlying thesis is still intact, or if more active management might be warranted.

I hear you. While DCA is fantastic for long-term consistency, there's definitely a point where you have to wonder if a company's fundamentals have shifted. It's not always about timing the bottom, but knowing when to re-evaluate your thesis.

Good point. DCA makes sense for a generally upward-trending asset, but for something showing persistent weakness, it can definitely feel like catching a falling knife. There's a fine line between averaging down and just bleeding capital.

DCA definitely has its place for long-term accumulation, but for something like $MRVL with its recent price action, I agree it feels more like catching a falling knife. I'm still a believer in technical analysis for entry points, especially with this kind of volatility.
