Ok, ok, ok, "this is like the tech bubble in 2001", "tech bubble, tech bubble", "overvaluations" , etc.
I get it, I personally would be cautious to take the ride further up, some people might say, ride the wave with the fed, with the bubble and that's cool but do it with very very smart SL positions as it can come crashing down fast as fuck.
Now, Elliot wave people would know the expanded and running flat corrections. You have wave B higher than start of wave A and then you have a wave C either lower than end of wave A (expanded) or higher than end of wave A (running). Afterwards, you would have a trend continuation move up with a move similar before the correction.
On the chart, I have circled possible zones for end of wave B and C but this is channeling the crystal ball too much - it is best to trade after confirmation. So on the daily chart we will start noticing divergences with the indicators - that's a good spot to short, check other timeframes as well for confirmation. Perhaps even wait for the first wave down of the wave C to go short.
Then ride it till you take some profit somewhere above end of wave A as a precaution and check price action there. I personally think it will do a expanded flat to trap more shorts before going up and continuing the trend.
Then again, the bubble could just swell further up parabolically but it doesn't look like it has much time - it is going freaking vertical each day. There are definitely some troubling stats: the top mega-caps are up 32% YTD while SPX remaining companies are -6.6% YTD, the NDX is about 70 companies in green YTD but you can definitely say that the mega-caps are pushing this up but it is too much tbh.
End game: short then long.
