The pattern seems consistent but is slightly shifted due to the dividend.
Now is perhaps the down-trending period before ER/D. I actually don't think the result ER will be highly correlated to the trend although it gives a hint to the overall direction.
BTW, I believe the ER will be super good, but the market reaction will be whether the company has plans to convert the supply crisis to real profit.
As a long-term investor, I believe the best entry point will be 4-6 weeks after the dividend date if you are inclined to own this company stock with the averaging buying strategy. Adjusting point for exiting might be a few days before the MACD converge point (+0.25 or above) after the dividend date.
