Any thought on buying GM before ER?

So tomorrow are GM's ER and I was thinking of buying because if you look at the chart there is some RSI divergence. So maybe this is signalling that there is going to be be good earnings.

I've never bought any company before their ER because of volatility and seeing how the market is over reacting lately it may be a bad idea.

I believe GM is going to be the next EV giant, so now seems like a good time to get in.
